His Themes (yes plural\*); his adorableness; his time with Chara; being: THE GOD OF HYPERDEATH!; being a good brother; and Flowey still being affected by even a small fragment of his soul.
\* His Theme, Hopes and Dreams/Save the World, etc. :)
Everything from the soundtracks tied to them to his entire story, when he met Chara, became Flowey, and revealed himself as God of Hyperdeath. I love this goat brother.
lore, also the hyperdeath design looks epic (not a furry i just think it looks cool)
His design, boss theme, personality, lore, and OMG furry sighted YAHHHOOOOO!
Music, character design, story, his Royal fluffiness 💚 (I wanna hug him)
Since this is about me, I would say my compassion is one of my most key factors of, well, being me.

Add in the hug and his likable personality and you got yourself the greatest character of all time
Same with me :3
His cuteness and connections with Frisk. I just don't love it when they ship Asriel and Frisk...
I know. The Undertale community forgets that Frisk is a CHILD.
But gotta say, they do look cute as siblings. ((No, I'm not a pedo and you surely know the reason))
yeah, don't worry. they do look cute as siblings tho.
His design, his story, his theme, his cuteness 
all of those are exactly what I chose too.
