Dr. Simon Lorch is obsessed with concocting a potion that will turn a man into one that possesses primordial strength. After five tries, he drinks the sixth one himself and turns into not only a man who has primordial strength, but is also a primordial beast! He goes on the usual killing spree until he is stopped (aka killed) by one of his previous experiments. Poor Dr. Lorch, he should have stopped at five tries!
This one's from Ace's WEB OF MYSTERY #3 (June 1951) with pencils by Mike Sekowsky and inks by Vince Alascia.
NOTE: I've began to go back into some of my earlier posts and started adding labels that are descriptive of some of the common themes found in pre-Code horror comics, such as today's "mad doctor" trope. I'll be including things like cannibalism, hanging, etc. when I come across them. This will be a work in progress for a while.
