Do you have more Quackity head canons? Maybe pumpkinduo?
Yes actually!! I'll start with quackity headcanons. please be warned there will be substance mentions, also mild-servere gore (I guess??), physical trauma like scaring talked about, and possibly violence as well. There is also talk of Cannibalism.
Okay so I'm just starting off right away with the headcanon that Quackity is always wearing between elbow length and like mid upper arm, like bicep area length gloves. The reason he does this is not only for appearances in las nevadas but because he has severe burn scars completely covering his hands and forearms up to just below his elbows. He also has severe burns his legs to about his knees that are more severe than his arms. These scars are from when he jumped in the lava after Charlie slimecicle fell in.
Quackity being trans masculine, I know a lot of people say this but I think it fits him. Especially in presentation in the server/ fannart alot of the time, kinda actually reminds me of myself. Start of the server- sweatshirt sweatpants / cargo shorts, short hair and a beanie. Then kinda finding himself more comfortable in a role of power, and with the suit as VP in manburg, and when he finally finds full power of his own, really leaning into the suits, and button ups/more formal look.
Quackity I think has perpetually sharp teeth, maybe not like sharp and serrated like sharks, but pointer then normal teeth.
Okay onto ones that are a little more pumpki1n duo related
If jambo is real in the dsmp canon (I think he is) quackity took him after schlatt died.
Schlatt wasn't great to quackity, it was definitely toxic yaoi. But when he was in his more sober moods, when things are going well politically schlatt would be better to quackity, like complimenting him, their shittily dancing together In their schlatts study or quackitys office.
Schlatt got quackity a pair of cufflings he still wears occasionally in las nevadas. This was a flirting attempt from schlatt. The cufflings are gold, each engraved with a cursive "Q".
Quackity is a clothes stealer. Any and all of his relationships, he has at least one item of clothing from each that he took.
Quackity mostly smokes cigarettes, but sometimes when he's feeling nostalgic or has an old craving, he smokes the same brand and same type of cigars schlatt would. Schlatt used to occasionally share his cigars with quackity, and while quackity didn't used to be a fan, and they're still not his favorite, they give him a specific nostalgic feeling back.
When Q drinks he mostly drinks wine, or champagne, but there are occasions, mostly schlatt's death date and birthday, as well as anniversary of them becoming president and VP, he'll drink whiskey.
When Schlatt died, Quackity ate his heart. It was partially of rage and partly of grief. Quackity was pissed at how he managed the country and when Schlatt treated him poorly, but he did care for him, he was abandoned that day. I think Quackity also keeps schlatt's skull, cleaned and on display in his las nevadas office with two of schlatt's old rings with big gems in the eye sockets like he's watching.
Honestly I probably still have more headcanons but these are just the ones I can think of rn :]
