OKAY, so. Full overthinking Doise (and Peddito) headcanons incoming (assuming they're real and not just fictional characters made up for Noise's movie):

I have this idea that Doise is actually from an alternate universe, and he's that universe's Noise equivalent. He's been fleeing for years through tower secret portals and gates to various other universes in an attempt to escape Peddito (aka his universe's Peppino equivalent turned vengeful cosmic horror ghost, obviously), specifically by trying to lure Peddito to kill Doise's alternate universe counterparts / doppelgangers / whatever to try and cheat the curse. It doesn't work, obviously, but he's selfish and willing to try anything at this point (despite superficially acting like a far nicer guy than Noise).

This is also why he appeared on the NTV movie set-- maybe he actually signed up for the role and made it seem like just a funny acting gig while hiding his ulterior motives, or he appeared to fight Noise completely unscripted and Noise and the others just shrugged and left it in, brutal murder and corpse and all.

Doise brought this all upon himself in the first place by being responsible for Peddito's death in a certain incident that may or may not have involved messing with supernatural / cosmic horror forces. They used to be good friends in their home universe, but that's long gone. Doise refuses to take responsibility for any of what happened and would rather spend the rest of his life desperately running from the consequences of his actions.

In addition, through Doise doubling down and continuing to mess with forces he shouldn't in his attempt to avoid Peddito, he has granted himself a limited form of resurrective immortality as another way to cheat death. As implied through his boss battle background (and, although it's just a silly noncanon thing, the pre-update DOOM mod stream having two Doises also inspired this idea), Doise can body-horror mitosis and bud off into another Doise that has all of his memories, so him getting brutally murdered in-game does not mean he's gone for good, as long as he remembered to create another Doise beforehand. However, his soul is divided equally between all his bodies despite them being mostly autonomous beings from each other, so not only does he struggle to use this ability beyond creating two or three extra Doises, Peddito can sense and hunt down all of them the same.

Peddito, meanwhile, has been utterly fucked up and transformed into a true supernatural horror by whatever happened, and by this point he will not rest until Doise is dead and dragged down with him. He will brutally kill whoever is in his path to murder Doise, but assuming Doise isn't currently present, he's creepy but surprisingly benign to everyone else-- albeit uninterested in socializing. He follows most vengeful ghost rules with a dash of creepypasta logic, and just because he isn't currently manifested doesn't mean he's not watching.

(Also Doise and Peddito's home universe is probably home to a full cast of knockoff "original character do not steal" counterparts relative to the Pizza Tower universe, which is really funny to think about. I imagine Peddito was a pasta chef and Doise was a Broadway actor.)
