He is one of the stupidest characters, but he has shown brilliance insight on many occasions that Brain hasn't
He makes up for his lack of science and math with his pop culture knowledge
He alongside Brain was the 2nd newest character to debut and help the heroes in The Great Time Travel Adventure.
He and Brain have a similar relationship to Maka and Soul
