wario + shadow both know their way around a gat
mario + sonic are both overrated
luigi + tails are both in the shadow of the main character
peach + rose both pink
yoshi + knuckles both portrayed as stupid
daisy + blaze both pretty irrelevant
waluigi + silver both will never be in smash
bowser + eggman both fail constantly
bowser jr + metal sonic both created by constant failures
donkey kong + alligator dude both fan favorites for reasons I cannot comprehend.
I guess this checks out.... I guess
