Bulldog Denny was really Denny Dunsan, a relative of Dr. Frankenstein. He took it upon himself to capture/destroy his relative's creation Frankenstein.

However after being summoned to Washington D.C. for a defense contract, Bulldog put his fight on hold and asked Green Lama, Black Owl, Yank & Doodle, Dr. Frost, and the General and Corporal to fight the monster in his absence.

The name Bulldog Denny comes from the fact Denny was said to have the tenacity of ten bulldogs.
