What is a "Genius Bruiser"?

Do You Know whats worse than an Opponent who is eaither Brains or Brawns?

Having an Opponent who is BOTH AT ONCE!!!

A Big Guy who is also a geek or tech-head. Often coupled with Gentle Giant in a dual subversion (not to be confused with a Double Subversion).
Basically what happens when you put Brains and Brawn in one character.

The complete opposite of Dumb Muscle. This guy has not only huge muscles and fists, but a very bright brain! There is, however, a difference between "especially smart" and "not a total moron".

A character who is strong but displays frankly average intelligence is simply not an idiot. But if they constantly spout endage in very long sentences and are considered an expert in some scientific field, that's especially smart. Similarly, if they're especially smart, they must also be unusually strong to qualify. "Beats people up" or "very physically fit" don't exactly count.

This character well portrayed. I feel the James Bond, Bourne Legacy etc. have that as their character Strong and very Smart.

I like the example you gave-
