I know nothing about Critical Role. These are some characters' impressions I got based on fanart
• fabulously dressed lavender tiefling ready to slay
• twin(?) elven siblings with long-ass generic pill names. I think archwizard Xanax and magister Ibuprofen are an actual part of their bloodline.
• unhinged little goblin that laughs in the face of gender identity
• that one two-colored half-orc that is tuskless(?) for some reason so I'm assuming Trauma™
• pink-haired Greenpeace firbolg
• that one ginger human wizard (?) that gets shipped with EVERY. SINGLE. CHARACTER in this damn fandom. Seriously, he gets passed around like a blunt. Also, I've never seen a single fanart of that man where he doesn't look absolutely MISERABLE, so I'm assuming he's some kind of depressed Victorian child.
I love DnD and I'm about to watch Critical Role for the first time after years spent seeing fanart made by the fandom without having any context. This are the characters I know about so far, and I've got no idea if this is the right impression or not. NOBODY CORRECT ME, I have to figure it out on my own. ( Btw I've no idea how many campaign this has or what season each character is from.)
