Igor (Hi, Spy!)

Igor was a short-lived assistant to Boris Brainyov.

Physical appearance
He was a large Caucasian man who appeared to have a shaved head. He wore a green military uniform.

Personality
Literally too dumb to live. Ordered not to throw a bomb, he instead held it until it exploded.

Scooby Doo... Where Are You! (Charlton Comics)
He was supposed to assist Brainyov, but instead was a spectacular failure.
