Alastor vs. Alastor (HH x OC Headcanons)

                                    

                                          
A03 request: Alastor from HH meets my OC Alastor
I don't usually do headcanons here (most are on my tumblr) but since it's a crossover I felt a little more inclined to do this instead of a full out one-shot.

So it's easier to differentiate, I'll be calling Hazbin's Alastor "Al"

-Their initial reactions to meeting each other would be to size each other up
-Both are powerful, though Alastor isn't the type to fight just to prove his power—it takes a lot to make him use his powers outside of luring victims and even more to bring out his full strength
-If they did end up exchanging blows it would be more out of the fun of causing chaos together than to actually kill the other one
-Causing fear in others is something both would enjoy doing
-Alastor however, isn't too keen on gore though so Al's way of doing things can be a little too messy for him
-He enjoys using full immersion hallucinations to attack his victims and if they die it's usually their own fault or their body just can't take the stress/fear and shuts down
-It'd be even worse if kids got involved
-Al doesn't mind seeing children suffer and isn't much of a fan of them
-Alastor on the other hand claims to dislike children, though has actually raised an adopted son, Luck, who was a half-demon half-human kid and loves him dearly. He may not have attachment to any other kids but he does have some moral code against it due to how it would remind him of how he'd nearly lost Luck in the Slender/Zalgo war
-Al likely wouldn't be impressed by him though
-He enjoys looking classy while Alastor mainly goes around in a loose fitting cloak, simple black pants, and boots to "show off" his looks
-Alastor also claims shirts are uncomfortable and hard to get on/off with his horns
-If Al made comments about it Alastor would probably get offendedAlastor's rather vain for someone with an obvious lack of style
-Al is also very passionate about food so if they met up to eat he'd definitely talk about his favorite dishes, or ones his mother made
-This wouldn't be so bad if Alastor could actually eat food, as doing so makes him feel sick
-This is attributed to the fact he was never human and while he's labeled as a demon, he isn't a classic demon like Al and is more labeled as such because he looks like one
-Alastor is actually a type of operator like Slenderman, The Operator, and Zalgo (who is also labeled as a demon)He's sustenance comes from feeding off fear and sanity of others, which doesn't always mean his victims die but it is likely
-They'd both totally be up in each others personal space
-Al would do so because he has no regards or care for it, plus many find it unnerving
-Alastor does so because his power over others can increase with physical contact, even after the contact is broken
-A real breaking point to their meeting, if the gore bits didn't do it, would be the flirting
-Alastor wouldn't necessarily find Al attractive or want to be with him but since he enjoys getting close with some of his victims it can be a sub-conscious thing he'll start doing until shown/told it isn't appreciated
-Alastor, while inspired by the demon from mythology, also takes inspiration from the Incubus
-To be honest, he'd probably like Angel Dust a little more since the two would have a more similar interest in this area
-These actions have also died down since he got into a poly open relationship with Ethan and his girlfriend, Emma (two other ocs) but he's immortal and old habits can be difficult to break
-Al may tolerate him at the end of the day if the two could figure out the boundaries each have but a friendship is unlikely, as the two can have very different views on things. The fact they both have a lot of power would also be something to drive a wedge between them given they'd never fully trust the other not to turn against them
I have a few more  on my tumblr (drrealityslenderverse), I tried to tie some into this but a few may have slipped through. There's also some headshots of him to get a better idea of what he looks like
