So I have some headcanons for Delta

!!!MY AU!!!

- Delta knows all the languages (he got bored one day, decided to see how many languages there were, and just straight up learned all of them)

- Mainly speaks Spanish

- Very overprotective

- Has the ultimate resting b*tch face

- His angry smile and his normal smile are the same thing; the only thing that differentiates them is his body language and his tone

- He's really intimidating when you first meet him, but he slowly warms to you

- Usually polite until someone makes him upset (ex; he's nice until someone says something sexist or misogynistic. Then he'll be ready to beat you)

- Doesn't like cussing (he will only do it in really specific situations)

- When he gets really mad, he starts going off on people in Spanish and it is terrifying

- He can see and hear ghosts (since he's fused with a Soul, I think he can see and hear other ghosts)

- He has hallucinations (in my AU, Delta had PTSD from all the things he's seen both from the surface and from the Multiverse)

- He can't see in the dark. At all. (He can see his hallucinations clearly, though)

- His senses are really good; he notices everything. Even the slightest change around him (ex; if someone changes their hairstyle even just a little, Delta is the first to notice)

- He can't sleep at night for two reasons. One, some of his hallucinations are murderous. Two, he usually has nightmares when he sleeps. So he just prefers not to sleep, ever.

- Casually says "fight me"

Let me know if you want more!
