Kings Ranking Pokemon Any Ghibli Hi Score Girl Kotaro Live Alone (It's sad but kid friendly) The star wars anime (disney plus) Astro Boy Somali and the Forest Spirit Sleepy Princess in the Demon Castle (its weirdly fun for both boys and girls) Kotaro Live Alone (It's sad but kid-friendly) The star wars anime (Disney plus) Original Bayblade (Start there) Detective Conan

Somali is a pretty cool choice, short, interesting and without much that can bother

Unless you count crying like a fucking baby to the story as something that's bothersome.. then it's great!

Somali is a heartwarming one but every episode makes me cry tho lol 😂

> Any Ghibli Princess Mononoke is perfect for a 10 years old kid!

Ok. I just started high score girl last night. It’s adorable. I’m only 2 episodes in I also saw kotaro lives alone. Seems like an interesting premise.

OG beyblade started airing when I was 10. Life-changing stuff! But I'm not sure how much of that was the toys.

Astro boy isnt anime

What? Astro Boy? Osamu Tezuka's Astro Boy?

If Astro Boy ain't anime, what the fuck is?

Cells at work! is a really cool scientific anime if your kid is interested in biology

Took me a long time to see this. This is perfect

Just the original version. Cells at Work Code Black is a little scarier for kids.

Wait you think sexy jutsu is bad but one piece is okay. Wtf? Imo one piece has way way more fan service than Naruto.

This is an... Odd post, right? So he's too young for Naruto but OP thinks he might be old enough for stuff like Vinland Saga? Whether he's not sensitive to it or not ain't the point dude. You definitely shouldn't be showing that to a 10-year-old.

Well yeah while what u said is true but in my own experience children are not as immature as ppl think while yes imo vinland saga might be too dark for 10 yo but i'll still recommend something like death note when he becomes 12 or something. My sister also watched it at that age and its ok. Though again vinland saga might be too much especially for a 10yo. Also naruto is a pretty good anime for a 12 yo. The thing is there are very few anime specifically for ages 10 imo. The op's brother is just too young for most anime period. Also if you read it they say he is a horror fan and has watched horror stuff. Now i dunno about u but a 10 yo watching horror anime or movies is a bit much.

Yeah exactly. Death Note and Naruto are perfectly fine at 12 I think. If at 13 or 14 and my son was watching Vinland Saga, I wouldn't bat an eye, just think he's going through an edgy phase of puberty. But 10?? Yeah, no way.

I mean that's a pretty typical American mentality. Boobies bad but decapitation is fine.

while i agree , in general the level of violence might be inappropriate for that age, i think the message is a good one and an age apocopate, so if watch with an older person / adult to add context , i think it could be fine . they might lose interest in season 2 , lol ​ edit for really bad spelling

Hard disagree. No way I'm letting my own son watch Vinland Saga at ten, even supervised. Thirteen, fourteen, sure - they might just see it as an edgy show. Vinland Saga sends the *worst* kind of message to a kid that age. Are you insane? Sure he *eventually* learns that he has no enemies and the path of vengeance is wrong and so on, but it's a full season of him being a brutal murder machine before that happens. Season 2 sees him course-correct after seeing the error of his ways, sure. You know what the average 10-year-old is gonna think of Season 2? "Huh? Where's the action? I'm bored, dropping this now." You even said it yourself.

I had the same reaction ☠️🤣

Naminaminaminaminaminami

Naammi swaaan indeed! ( dies from peak fiction)

See, its less of a he's too young for sexy jutsu, its just we are watching anime in the family room on a 55" tv. Plus naruto has way more fan service upfront that one piece. The character designs are sexual, sure, but its not as bad atleast in the beginning. By the time he gets to time skip when it starts going a lot harder on it, he will be a little older. Naruto is just way more blatant than one piece. Also, the naruto anime is like 1/4th filler, so id rather just have him read the manga. He's totally mentally able to comprehend stuff like vinland saga. And again, he likes horror, so he's seen a lot worse when it comes to violence.

Dr stone is really good as well

I could see some parents having issues with some of the more violent scenes. But I, personally with zero kids to my name, would say it’s well worth it for opportunity to get them hooked on science early on. Dr. Stone gets me as jazzed about science as Bill Nye the Science Guy, Neil deGrasse Tyson, or that zany Texas A&M physics professor (Tatiana Erukhimova for those curious)

Multiple butt booty naked characters

SpyXfamily😊 wish my Sister would watch anime with me😆

Ahh, frrr. My sister makes a point of not watching any animes... Although, she did watch the first season of Demon Slayer and kinda enjoyed it. Refused to admit it tho--

Yes I think they just feel its wierd or whatever because of stereotypes so theyre afraid to like it/try it, my sister watched like 1 episode of AOT and said its so bad... like bro u havent even started watching😆

Yeah, it also sucks that when they do sometimes watch it, fan service would just come up out of nowhere. So now, my sibling has this whole idea that anime is for weirdos--- I don't like fan service, but I was watching One Piece, so like, kinda hard to get past it--

Inazuma Eleven and Dinosaur King are pretty cool. Zero sexual stuff from what I remember

1. Hikaru No Go, 2. Magic Knight Rayearth 3. Almost all Studio Ghibli films 4. Pokémon 5. Digimon

Gurren Lagann? If sexy jutsu is too much fan service Gurren Lagann isn’t appropriate

[удалено]

A bit? lol.

I would substitute all on the list for the anime with the toy products like Pokémon, Digimon, Bakugan, and Beyblade. It’s all towards kids. Pui Pui Molecar. It’s stop motion and it’s good. It’s not anime. Demon Slayer doesn’t count even though most of the characters are of adolescent age.

I second Rayearth

G Gundam

Going to make my brother a gundam chad now, thanks lol

Honestly, show him some Gundam stuff, I mean iron blooded orphans and Gundam 00 are very good and one of them is more bloody and the other one more political which is inevitable in Gundam but ykwim

Doraemon

>Anime to watch with a 10 year old Boy My hero academia Black clover

Came here to say both of these. Very power of friendship (black clover more so). The ONLY suggestive themes would be 2-3 characters wearing some suggestive outfit but… there’s not really a show that doesn’t do that. Even back in the day.. we’d be ogling favorite characters as a kid.

>Came here to say both of these. Very power of friendship I saw people who reccomended op Berserk or Highschool of the dead but thats not somthing a 10 year old should watch imo. These felt more safe

Naked witch

I don't know about My Hero Academia. If OP doesn't want an anime series with sexual innuendo, then they are really going to have a problem with Mineta and Midnight. Although, if they are bothered by sexual innuendo then why are they letting their kid watch One Piece is beyond me.

>I don't know about My Hero Academia. If OP doesn't want an anime series with sexual innuendo, then they are really going to have a problem with Mineta and Midnight. True enough but op will have a problem finding shows without fanservice >Not to mention some of the really messed up stuff later in the series. Op said that the kid was fine with horror and i rather reccomend My hero academia then somthing like Beserk

Sexy Jutsu is pretty tame compared to most ecchi, and I was 10 when I first watched Naruto. A lot of Shounen Jump is gonna be your best bet, Pokemon, Yugioh, and Bakugan were also Saturday Morning staples for me

Hunter x hunter

Noragami - action comedy with a bit of drama and it has ghostlike monsters (ayakashi), fanservice very tame: there's one lady in a bikini riding a flying lion and that's it. [Here's a trailer.](https://www.youtube.com/watch?v=IQnnwUXd_0U)

run with the wind Another Natsume book of friends Sword of the stranger

Yu Yu Hakusho is great!

One Punch Man is a fun show. Mob psycho too. Spy X Family is great too for the family to watch.

Berserk

Based, but unfortunately not yet lol. Im waiting until hes in highschool for that one

Zoids

While it’s not out yet Delicious in Dungeon is an upcoming show that’s perfect for younger audiences. While not anime also consider Toku shows like Kamen Rider and Super Sentai! I’ve got an 11 year old myself who’s into manga and anime so I know the woes of wanting to show them stuff but there being so many good series that are hard nos because of lewd shit. Other stuff I’ve let my daughter watch/read that she really enjoyed: - Blue Lock - Spy X Family - Girls Last Tour - Komi Can’t Communicate ( though that one stalker girl is kinda borderline) - Ranger Reject - Full Metal Alchemist - Silver Spoon

The Promised Neverland is pretty good

Stop

Related to horror (possibly): Death Note (more of a thriller but it’s got that cool feel?) Normal: Spy family and Frieren

Dragon ball z

Big-O Cowboy Bebop Yuyu Hakusho Ruroni Kenshin DragonBall and DragonBall Z Any of the Gundam shows Jojo's bizarre adventure Yugioh Any of the pokemon series Digimon

Demon Slayer would probably be a good mixture of horror and shonen tropes fit for a 10yo, without any sexual themes (apart from the occasional fan service-sized pair of boobs)

Urmmm tengen slaps the girl on her bum

True, the Pleasure District Arc in general has most of that stuff.

Bakugan, Kuroko no Basket

maybe bleach? I don't remember anything sexual about it at least

There's Kon and Keigo in the first part for perviness, some fanservice with Yoruichi in the SS arc, and if Sexy Jutsu is too much for OP, he probably wouldn't like a lot of Bleach's outfits lol.

Man forgot Kon.

Kuroko no basket, Ranking of Kings and maybe FMAB?

Dinosaur king, I second. Before I left my girl watch naruto (its rated PG btw) she watched the whole of the pokemon orignsl series, yugioh then dinosaur king (it has the same cast as OG pokemon) My neighbour totoro, haikyu, my hero academia (not the recent series its quite dark), fairy tale (bit touch and go for the "sexy" stuff but I also watched this with my daughter and she loved it), spirited away, howls moving castle, ponyo, avatar the last air bended (technically not an anime but a great show), digimon... If I think of more I'll come back

- One Punch Man - Blue Lock

i mean as far as Naruto goes, it originally aired on cartoon network and is mostly y7. i watched the broadcast and dubbed version so i dont know if theres a version that is more revealing but i didnt find that show inappropiate to watch in front of my really conservative Babtist foster mom . lol as far as the shows with the least sexual content at all that would appeal to that age . most battle shone =n are perfect. FMA brotherhood. attack on titan, HXH wil get you pretty far

Pokémon or Yugioh or Bakugan. 100% kids show with a product placement. They are technically anime.

I wish I watched around that age "Uninhabited Planet Survive!" / "Mujin Wakusei Survive". It would be my favorite. It's a truly children's TV series, but it has surprisingly strong story plot.

Hikaru no Go is a great one Megalobox Season 1 might be good for him, but I don't think Season 2 would be appropriate for a 10 year old. If you're open to movies, there's a bunch of Ghibli films that are good for that age: Castle in the Sky, Nausicaä of the Valley of the Wind, Spirited Away, Ponyo, The Secret World of Arrietty, and many others. Just steer clear of Grave of the Fireflies (and maybe Only Yesterday, The Wind Rises, and Princess Mononoke) until he's older. Depending on your ability to watch older anime that aren't on streaming services, Treasure Island and Future Boy Conan are also quite good.

Looking for some that haven't been mentioned yet. I think HunterXHunter would be a good one.

Sexy Justus is nothing compared to the fan service of one piece my guy

Mob Psycho is a good one though he won't understand it's social themes School babysitter is also a good light hearted slice of life and if you want an anime free of fan service than romcom/slice of life would be your best bet

kaitou joker!!! i enjoyed it so much despite it being aimed at preteen boys. it's a bit niche but so so so cool and has neat fight scenes!!! the OP is also an insane banger

Obviously, it's your kid, so parent however you see fit. I will say that Naruto should be fine imo. The Sexy Jutsu doesn't appear too often and is still pretty tame. Chances are you'll be more uncomfortable about it than your son will.

Demon slayer

There are so so many awesome anime but As far as 10 years olds go there is one anime that reigns supreme, it's easy to follow, easy to understand but isnt too childish, this anime is of course. Dragon Ball Z - your brother will thank you. DBZ may be the most "overrated?" Anime ever but it's for a reason, it's extremely easy to watch for a kid.

Since he likes horror, perhaps higurashi (no naku goro ni)

I really enjoyed watching BlueLock but I did warn my son a head of time that they do curse 3 times. But he knows he’s not allowed to curse.

Cursing isnt too big of a deal, and its handled the same way in our house. I dont even curse in my 20s around the house, but the entire family does. Just a respect thing As for blue lock, absolutely a good choice, adding it to the list

Trigun (Just a good show, and if you watch the reboot their is absolutely nothing. i think it's the sane for the original, but I just haven't watched it in a while) Hunter x Hunter (my favorite show) (Will scar the child deeply from dark moments and has the character named hisoka, who is a very passionate guy about fighting and "potential" power. but otherwise lacks most forms of fan service, just be careful with it due to it potentially scaring more timid children)

\*\*Natsume's Book of Friends\*\* has some thriller and horror, plus no content that a 10 year old or watchful parents couldn't deal with. \*\*Detective Conan\*\* as well, but that's a commitment.

Dragon ball z has basically zero sexuality in it and the violence is pretty cartoony. One piece is similar. Edit: also reading through the comments this is clearly a bad place to ask for recommendations for kids. Unsurprisingly when half the sub loves lolis they have no idea what's appropriate for children.

I cant confirm or deny your edit, but DBZ is definitely good. Shame though, id prefer to start him on the og dragon ball, but, you know, its a little bit out there sexually.

Yeah, I thought about it a little more and Dr stone is a fantastic one for kids. Minimal violence almost no sexuality and no super twisted moments.

kiss x sis. gotta teach em young

Digimon, Spy x Family, FMA: Brotherhood maybe even?

FMAB I think is too violent… maybe around 12-13

I'd second this! FMA/FMAB has some horror that is, while not very graphic, pretty disturbing in a psychiological way. The part with the girl and her dog - you know what I'm talking about - that's outright nightmare fuel.

Here are my suggestions...a mix of modern classics and some newer stuff! ​ ​ Mob Psycho 100 One Punch Man Spy x Family Hunter x Hunter (2011) Fullmetal Alchemist Brotherhood Code Geass Samurai Champloo Fate/stay night Unlimited Blade Works Megalo Box Gundam Iron Blooded Orphans Saga of Tanya the Evil

dark gathering megalo box

Meglobox, if i remember correctly, is exactly something i was looking for. Thanks for the reminder!

Re:zero? That is definitely not appropriate for kids. Nor is hunter hunter. Full metal alchemist also has its moments (the chimera comes to mind and resurrecting mom)

Fma:b is not for children

Redo of Healer

Inuyasha

The pervert monk going around groping women kinda sinks Inuyasha for kids.

I watched it with my little sister when she was 8. Nothing really inappropriate ever happened and it was played off as jokes so I think it would be fine.

I watched Naruto with my now 7 year old when she was 6, she's completed it and is now watching Boruto 😅🤣 Like to the point my child is obsessed with naruto, only mentioned sexy jutsu once and never again aswell

Show him Baki

I already beat him, im the yujiro to his baki. Ill make sure to brew him imaginary tea while we watch it

Hunter x Hunter I think you guys will really like Hisoka.

Rosario + Vampire High school dxd Fire force Seven deadly sins

Hunterxhunter da best.

Let him watch the promise neverland

Stop

Why

He’s 10. That’s a pretty dark watch for a 10 year old

Jojo

Detective Conan Bakuman Doraemon Card Captor Sakura Haikyu!! Kuroko no Basket My Hero Academia Dragon Ball Z Avatar: The Last Airbender (although technically not an anime) Any Ghibli movie Digimon Beyblade Yu-Gi-Oh! Pokemon Sailor Moon ​ Personally, I think that Detective Conan and My Hero Academia is the maximum of violence a 10-year-old should be exposed to and that Vinland Saga is not suitable for that age.

Try Naruto it does have blood and a few swears if your okay with that.

They specifically said Naruto was too sexual for what they're looking for.

Ah snap my bad, I only skimmed over it. I guess dbz is out of the question then that can get quite brutal and bloody. It’s a shame but all the good animes do tend to have some sort of perverseness in them.

well they specifically mentioned horror as a fave genre for the kid so blood and brutal is probably fine. at least as far as the broadcast edit for dbz it aired on a kids channel in a kids timeslot and was rated y7 so that should be fine for a 10 tear old. but the uncut version which would probably be what htey hve access to now online might have a few more adult elements like alcohol use and more blood, but then again , if the op doesnt feel og Naruto is apocopate then idk LOL. that also aired on kids station here on the states. heck Shippuden aired on the Disney channel and you know how picky they used to be about having a squeaky clean family friendly image lol.

Yeah but I also feel like there's no avoiding dragon ball z. My nephew is 8 and all of his friends are talking about dragon ball pretty regularly.

Yeah but it kinda makes sense. Adults don't like most kid shows for a reason. So most kid appropriate shows most adults won't consider good.

FMA brotherhood. There’s no fan service but there’s one scene around the end it’s not major though. Mob psycho 100 is 100% no fan service

[удалено]

Promised neverland is not suitable for a child nor is fma:b

[удалено]

Honestly I was like you what... for kids! I think the eff not 🤣🤣

Watch Naruto My man. Naruto was playing after school daily when I was 7 It was the talk of the playground

I don't really like sports persay but haikyu is one of my favorite shows. Another one that's almost as good is Kurokos basketball and all of it is dubbed on Netflix if you have yet to watch it.

fullmetal alchemist brotherhood.

Death note 😂

pokemon, dragon ball / DBZ, ghibli stuff, ATLA stuff, maybe samurai champloo / cowboy bebop / megalobox

Naruto drangon ball z

Dr Stone, Jojo (part 6 is where it starts to get a bit explicit), Mob Pyscho, Durarara, Ya Boy Kongming, Handa-kun, Haven’t you heard? I’m sakamoto. Those are the anime that I don’t think have anything bad in them, and they are all very enjoyable.

Fairy tail

Bruh fairy tale has so much fanservice

Prison School

Are you trying to be funny

Grand blue while im at it

Made in Abyss

naruto is fine but beside naruto maybe beserk?

Definitely he needs to watch attack on titan 10/10 highly recommend

Monster, Elf lied, and Bible Black

Monster by Naoki Urasawa

Highschool of the dead This was the first anime of my little brother and even now is one of his favourite! He was 5 or 6 when he watched it for first time!

????? why reccomend High school of the dead and not something more appropriate

You let a 6 year old watch highschool of the dead? That's really gross.

You’re acting like most of us anime fans weren’t watching weird anime at 10. Toonami had some weird stuff and we all came out good 🤣 it’s not even that bad of an ecchi. No nipples are seen.

Oh he didn't even noticed the ecchi part that much! I mean my mother likes in home is very often naked. And in my country this is not unusuall!

Why the fuck did you let him watch that

Ah, my first anime was in 6th grade. I watched kissxsis. Id prefer my brother go down a different path lol

And the other animes he liked were Shingeki no Kyojin, Kabeneri, D gray man and Avatar ( its not anime but)

> horror Dark Gathering [sexual themes]>!Has a love hotel episode at episode ~17. Pretty safe otherwise.!<

[удалено]

I bet they wiped that episode from their mind. Was pretty damn traumatic shit and i'm an adult.

King's game, Shangri-La frontier BTOOOM (it has some echii scenes but not too many and the action and the story are very good, you can watch it alone) High rise invasion MASHLE (has some blood) And maybe rent a girlfriend

If hes fine with death and horror stuff maybe give aot or parasyte a try. Id double check on parasyte tho cause i havent watched it in ages.

I recomend you watch Aot

Fate/Zero and Fate/stay night: Unlimited Blade Works

Goblin slayer, berserk, zom 100

Most older anime fans were watching some weird anime at age 10. Let him watch whatever he wants.

[удалено]

😂

Aki no Sora Interspecies Reviewers Redo of Healer

"anime to watch with a 10 year old boy" ​ **what do you mean by that?**

Quite clearly mean stuff thats suitable to watch with their brother... why you gotta make things weird

Maybe some gundam

gintama

Future boy Conan

Kaiji? It sort of meets the horror criterion (more like psychological horror than anything else, though), and it doesn't really have much in terms of fan service. It can get a bit graphical violence-wise, but based on your description it might not go too far for the kid. I would also recommend Hunter x Hunter (2011) and Full metal Alchemist: Brotherhood - both very good shonens with little to no fan service that I can recall, and with some parts that get pretty dark.

made in abyss

Ghost Hunt

Best horror IMO is Junji Ito Collection. Anything by Junji Ito really except Gyo: Tokyo Fish Attack though since a chick briefly gets double teamed in that one for some reason (but not in the manga)

ranking of kings is as wholesome as it gets and still has plenty of action

Toyko Ghoul is up your street I think along with Death Note and Berserk. D-Gray man, Soul Eater.. Fairytail could work. It has a little bit subtle fan service at times but overall it’s pretty acceptable and will keep him busy for a while. One of the movies is bad for it though. Demon slayer would also be good

Ranking of Kings, Megalo Box, and Blue Lock

Ghibli movies!!

AO Ashi is an amazing sports anime

If he likes any other sports and is enjoying haikyuu, you could show him other sports anime. Mob psycho is good. Hunter x Hunter. Honestly, I'd go onto MAL or anilist and just search/sort by the shonen demographic and sift through what you think he'd like and what you'd find appropriate.

I loved watching Yo kai watch with my son. He also loves Naruto (oblivious to sexy jutsu), Digimon, Pokemon, and most of the others already mentioned. I'm itching to get him into DBZ. See what used to be on Toonami back in the day that might give you some good suggestions too. Edited to add CardCaptor Sakura, Esacaflowne, and Gundam Wing

What kinda horror has he seen? The shining is one thing. higurashi when they cry is a whole other level. Something supernatural and with horror elements and yet still ok for kids like stranger things would be little witch academia.
