The Shuichi effect refers to a common inconsistency that can be seen in fanart for the character Shuichi Saihara, specifically the fact that his eyes have radically different colors from fanart to fanart.
This term can also be used to denote similar occurrences in other kinds of art/fanart
Jon Smith: Dude don't you find it weird that every time I search for fanart of Shuichi his eye color is different.
Harrington: Oh are you talking about the 'Shuichi effect'?

An emo hat that looks like it was copy and pasted onto each sprite, then adjusted with a perspective tool as needed.
