This has been bugging me forever, but uh...
WTF IS A TIER

 

[Rad Dudesman]

A tier is a ranking that fighting games have. Tiers are seperated into groups. The higher the tier, the better the character is. Tiers are listed from best character to worst. It also confirms that:

Dr. Mario > Mario
Fox > Falco
Link > Young Link
Captain Falcon > Ganondorf
Marth > Roy
Pikachu > Pichu
