Meaningful Name/Professional Wrestling

It is a long-standing tradition in Professional Wrestling for gimmick names to let fans know exactly what they're in for.

Kharma, who beats up heel Divas. In other words, Kharma's a bitch, and it comes back to bite you in the ass.
Sin Cara means No Face. This has a double meaning; not only does his mask completely hide his face, but due to legal necessity, he left his previous identity as Mistico behind when he signed with WWE -- in other words, he is now without the "face" he has wrestled under his entire career.
A man of mystery: Rey Mysterio, Jr.. Doubles that in Spanish his name is King Mystery or King of Mystery.
Pompous Brit: Stephen William Regal
Insane woman: Luna
Destructive giant from India: The Great Khali [sic]
Pain-bringing Wild Samoan warrior: Umaga ("The End")
Corrupt taxman: Irwin R. Schyster [sic]
Evil dentist (yes, dentist): Isaac Yankem
- Who later became jealous, murderous brother Kane.
Angry Scotsman: Roddy Piper
Japanese silent warrior with facepaint: The Great Kabuki
Adult film star: Val Venis (Rhymes with...)
Texan cowboy brothers: Billy and Bart Gunn
Gothic vampire: Gangrel (They even gave White Wolf credit for the name when licensing it!)
Little Richard-style flamboyant rock'n'roller: Johnny B. Badd
That said, that heel with all the pizazz was really born Ric (Richard) Fleihr, and the egotistical Ravishing Rick Rude was actually named Richard Roode.
Buffed out hero. Hulk Hogan (Licensed from Marvel, even.)
Treacherous Brother: Judas Mesias
Mexican wrestling legend Dos Caras (Two Faces) was so named because he was one of Lucha's first prominent tweeners; on any given night, he could be a Face or a Heel.
Though the same height as Kane, but The Big Show is called that rather his birth name, Paul, for a reason. He’s about seven feet tall and a super heavyweight… enough to break the ring upon a superplex. Just ask a former NCAA amateur wrestler and a Olympic weightlifter that… they learn about it the hard way.
