RSFF

From Board 8 Wiki

Reverse Same Fanbase Factor (or rSFF for short) is the theory that the "weaker" of two characters (using indirect statistics) can sometimes win a matchup by dominating the voting block shared by the two opponents. The idea behind rSFF was first brought up during the Summer of 2004, when it was suggested that, because the Chrono Trigger fanbase prefered Magus to Crono, the wizard would be able to rSFF his way to victory. He did not.

Though the debate is still out regarding the existence of rSFF, some claim its first proven case took place in 2005, when Samus, a character who had outperformed her Nintendo counterpart Mario indirectly in two of the previous three years, was nevertheless crushed by the Nintendo icon in a direct matchup (Mario earned 59.79% of the vote).
