Incredible Hulk #5 (Marvel, 1963) is the first appearance of Tyrannus, from the original six-issue Hulk run by Stan Lee and Jack Kirby. With the original series cancelled after issue #6, these first-run Hulks are all low-supply books — every one of the six is a key in its own right, and mid-grade copies are the sweet spot of the market.
