So, I made an Error Asriel/Flowey.
Basically, he’s like a parasite who can take over people’s bodies (and part of their minds too) to spread chaos upon the Undertale multiverse.
While he can only take over bodies in Flowey form, he uses his standard form to lure people into a false sense of security so they trust him. He can switch forms at any time.
As part of his facade, he speaks in a very cursed verbal diabetes. He’s not afraid of saying things like “UwU” and “Onii-chan”. He acts like a very innocent, slightly suggestive soft boy. It makes people unconfortable as heck, but he doesn’t care, because they’re all potencial “pawns” to him
