Best wrestling nickname?

What are you thoughts?

I’m sure a lot nostalgia plays into everyone’s thoughts.  But I would think it would have to be a nickname that when you hear it you think. “Dam- sucks no one else can use it today”

The Hitman

The Enforcer

Mr Perfect 

Nature Boy

Lunatic Fringe (just kidding)

Come to mind.

My personal favorite is The American Dream

What say you?

Conversely. What is the worst?

Apex Predator is pretty fucking stupid. 
For the good ones, the Russian Nightmare was a badass nickname.  Tells you everything about the character and the gimmick during the ring introduction. Also acted as a foil to the American Dream.
