Oh boy.

Okay so he has no fucking rizz at all and he acts entitled (if it's post comic 6, he uses God's excuse to manipulate them which is not believed). He's definitely and very obviously intruding on his obsession's life. He TRIES to be subtle and quiet by following them but knocks shit over ALL the time so they know it's him. He'll also pop in and intrude on conversations his obsession is a part of. He's unintentionally rude bc of his obnoxious nature and ego.

Scout gets REALLY fucking enraged when his obsession is leaving him in any manner, doesn't matter if it's one sided or established relationship. He will throw a FIT and stalk behind them angrily. Out of impulse, he may end up attacking them which either knocks them out/harms them grievously OR just pisses his obsession off MORE and gives them more reason to leave.

10000000% focused on impulse. Sure, he takes notes from time to time on important stuff like his obsession's favorite things but it's usually in the context of a impulsive and not thought out well plan. He acts entirely on emotion, logic is GONE. When he first goes berserk, it's after his obsession made him very very angry and so he just. killed everyone they loved bc he couldn't deal with his anger properly LMAO.

Scout when he's captured his obsession locks them in a room. He's not smart so they escape a few times before Scout gets ideas on how to reshape the whole living space. He doesn't do restraints but DOES use threats of force and sometimes force when his obsession attempts fighting back. He guilt trips them while having them in a chokehold of how he's just "trying his best" to make everything work. Of course, he only makes shit worse bc he'll end up breaking a bone of theirs and HAS to take them to the hospital. Also sometimes Scout treats them like a fucking child i.e spoon feeding them while having them tied down (Spy taught him how to properly knot when Scout told him about how he found another person to love again but Spy was unaware of the entire context RIP).

Engineer - Fascinated by the art and animation and tech that goes into it.
Pyro - Adores the concept and persona aspect. Has own Vtubersona.
Scout - Thinks it's cool as hell and tried to apply to an agency (Admin forbade him and maybe shot the whole agency). Also spent an embarrassing amount of money on them.
Spy - Doesn't want to admit it but adores sitting down for a cup of tea and watching a Vtuber's livestream.
Medic - ADORES the designs and draws a ridiculous amount of monstrous looking Vtubers. Shows them to Heavy who doesn't get it but supports him.
Demoman - Confused as hell by the concept but respects them like a online radio or TV host.
Soldier - Confused as hell and thinks it's witchcraft.
Heavy - Vaguely gets the idea of how someone might wanna present as cute when they're not physically. Doesn't understand half the terms Medic says but nods and agrees.
Sniper - He thinks Vtubers means vlog YouTubers so he "tries" to become a homemade Vtuber (as in posts literal vlogs of him in the wild) to own the mercs who're obsessed with them.
