Jon Jones. It's so simple yet so dominant.
Wanderlei Silva. His name used to mean a lot of terror.
Werdum; except for his first name.
Dan Severn. It sounds like a name of a boss character.
Robbie Lawler. Again, not so much his first name, but his last name sounds pretty cool.
Brock Lesnar. His name fits his character, so perfectly.
And names like Takanori Gomi and Kid Yamamoto sound pretty cool, too.
