Nobody who has ever fought in the UFC can claim the accolades BJ Penn can.
Double champ.
MMA debut with the UFC.
Fought in five different weight classes.
Penn will always remain one of the most interesting fighters with one of the most interesting careers in a sport full of interesting characters.
Penn shot immediately to the top of the pile when he took on Jens Pulver for the lightweight strap at UFC 35. After losing a close decision, Penn hung around until he grew bored of the lightweight division. Despite having success in the division, still with only one loss on his record, Penn threw himself into the welterweight shark tank and beat Matt Hughes for the 170-pound belt.
