Gigantus

Gigantus lumbers out of the early 1990s Copper/Modern Age courtesy of the legendary creative pairing of Walter Simonson and Arthur Adams — a pedigree that alone makes any appearance worth tracking down. This Marvel monster cuts an imposing figure in a compact but compelling catalog of just three appearances, rubbing shoulders with titans like the Hulk, Iron Man, Spider-Man, and Daredevil across titles including Earth X and Marvel Universe. Rare doesn't begin to cover it — for collectors who love their Marvel monsters massive and their back-issue hunts genuinely challenging, Gigantus is a find worth celebrating.
