Vivian:
Shrinking Violet - Describes Vivian perfectly. It doesn't help that he's violet anyway. Unsurprisingly, also tied with
Apologizes Alot.
All Girls Want Bad Boys - Secretly, Vivian kind of has a thing for the
Troubled But Cute. Which is not to undermine the following.
Sickeningly Sweethearts - Vivian and Lop are full of happily-ever-after diabeetus. Case in point: They have "you're cuter" exchanges ALL THE TIME.
The Woobie - In game canon, at least.
The Chew Toy - Has always been so for his sisters as
The Un Favorite, but has recently surfaced anew in other areas of his life.
Gender Bender/
Wholesome Crossdresser - The only other thing that makes Vivian interesting.
Honorable mentions: Cute Witch, Perky Goth, Troubled But Cute, Adaptation Decay, Canon Sue
DK:
Everything's Better With Monkeys - 'Nuff said.
The Big Guy/
Gentle Giant - DK is a very good example of this role. He likes to use his strength to help out.
Raised By Wolves/
Wild Man - Really, DK plays way too many tropes painfully straight. Elaborating is difficult, especially since he hasn't really been around the school much.
Honorable mentions: Book Dumb, Fish Out Of Water, The Brute, Flat Character
Pikachu:
Mon - Obvious.
Older Than They Look - Very much applies to Pikachu, though I know I play this trope badly. I'm workin' on it.
Genki Girl - Need to lay off the sugar much?
Cool Old Lady - Not as old as most, but probably more incompetent.
Badass Bookworm - She is a nerd about the art of battle, after all.
Every Year They Fizzle Out - Pikachu has never won a battle, have you noticed?
Glass Cannon - The reason Pikachu sucks, in SBG and in game canon. She's all talk, but she can't play her strength well.
Honorable mentions: Cool Old Lady, Non Human Sidekick, Hot For Student, The Chew Toy
General:
Old Shame - I have, on multiple occasions, gone through old sketchbooks and flushed every other page down the toilet one by one. This theme pervades every area of my artistic life, including RP to some extent.
Generic Cuteness - I'm pretty bad with this. Both when I draw, and in my choices of characters and depictions of said characters.
Ambiguous Gender - Applies to everyone. Vivian is obvious. Pikachu is pretty ambiguous because she's a Pokémon. And. Have you ever looked at DK's crotch in Brawl? ...Poor dude.
