Floyd Mayweather

Floyd Mayweather, is a featured fighter in the Def Jam series and playable in Def Jam Control.

Def Jam Control (Prologue)
Mayweather is seen in the prologue fighting with Ludacris before training Justin Bieber on how to fight. Although Bieber is shown to be brash and almost incapable of being accurately trained, after being told to focus on everything at hand and analyze it, breaking it down as if it's one of his own songs, Justin comes back and proves his worth to Mayweather. In the end Luda signs him to the crew, with Mayweather looking over him.

Def Jam Control (Road to Control)
Mayweather has very little relevence to the actual story and is fought once by Playa and a few other times by Redman, Joyner Lucas and Katt Williams.
