▶ VISUAL: The thing about Red vs Blue is that the only characters who have canon appearances are characters who were either introduced or expanded upon after RT had the mocap technology to do faces. Meaning, anything I say here is going to be entirely headcanon simply because Tucker's canon face is his helmet. That said, I like papanorth's Tucker a lot, although his ESH picture is from electricgale. Presently, I imagine that he cut his hair while he was in the desert, but that it's grown back out to something to match his profile picture. Basically his pb is more of an expressions/body reference than a hair length reference.
Also, since he's shirtless so often, I should note that he is littered with scars. The two biggest ones are on his back and his stomach, though. The big one on his back looks like some kind of impact/explosive burn from where he was shot with a rocket launcher, and the one on his stomach (the newest scar and one that he doesn't remember getting) looks like he was knifed. Also, around his stomach and hips he has faded, paler stretch marks that have an unnatural cyan shine in the right light.
▶ AURAL: Here is a montage of his catchphrase, since I linked a best of seasons 4 and 5 and his character song on the voice meme.
▶ OLFACTORY: Tucker has a general smell of spicy cologne, despite the fact that he's been in the military for years and no matter how cheap it is his access to cologne has probably been fairly limited. It's cheap and generic, and it can be kind of overwhelming if you're not used to it (Tucker, one spritz is enough). It also rubs off on everything and everyone he touches, although to a lesser extent.
▶ DEMEANOUR: Tucker is a loud, crude, obnoxious prick with an oddly endearing side. He doesn't really seem to have much in the way of a filter, and he's very flippant about things that should probably seem a lot weirder than they are.

▶ PHYSICAL AFFECTION: Tucker is basically a cat with people he deems worthy of physical affection. ...It doesn't take much to get to that point, either.
▶ PHYSICAL VIOLENCE: ABSOLUTELY fight tucker. why WOULDN'T you fight tucker??? have you MET tucker???
He is the best fighter out of the blood gulch crew, however, so if you do fight Tucker just make sure that he doesn't get mad enough to put up a real fight back.
▶ RELATIONSHIPS: Tucker talks a big talk, but physically he's in his 30s and mentally he's at least old enough to not skeeve on high school students.
▶ PSYCHIC & PSIONIC INFORMATION: Not really a concern in DRRP.
▶ MAGICAL INFORMATION: Nah.
▶ MEDICAL INFORMATION: He has lots of old (and new) scars, as well as magical alien stretch marks from his magical alien pregnancy.
▶ OFFENSIVE SUBJECTS & TRIGGERS: Nope not really, he's more likely to BE offensive than to actually GET offended, and he doesn't have any real triggers.

▶ BACKTAGGING: YES I will backtag forever. If I accidentally stop replying to an old thread, feel free to smack me about it because sometimes I forget or accidentally delete the notif.
▶ THREADHOPPING: If it makes sense in context, go for it! If it's plot stuff or otherwise seems somewhat private, let me know or ask first before you jump in.
▶ FOURTHWALLING: Unlikely to come up, but the only kind of fourthwalling I'm really against is the OOOH YOU'RE FIIIIICTIONAL kind so o7
▶ OFFENSIVE SUBJECTS & TRIGGERS: Nope, got nothing.

▶ ANYTHING ELSE? Tucker getting alien pregnant is played for laughs, and he is downright nonchalant about it so I will definitely never play it up for drama, but it is an important part of Tucker's character because he cares so much about Junior. If you want to avoid this subject, I totally understand.
