Half-Orc

A half-Orc is exactly what it says on the tin - an unholy fusion of man and Orc. Typically they get bonuses to physical stats (STR and DEX in 4e, for example) and tend to lean towards evil.

Basically, if you want to play a big, dumb, "I hit it with my axe" pure combat class, half-Orc is the race for you. Though in 4e, they make pretty good monks.
