The Super Smash Bros. series is a crossover between tons of different video game franchises, many of which have art styles that greatly differ from each other. However, the minimal, blocky aesthetics of Minecraft Steve manages to stand out even amongst all the other oddballs in the game, as best shown on the "EVERYONE IS HERE!" character art mural.
