Brutus

Brutus crashed onto the scene in 1991's The Incredible Hulk Annual #17, brought to life by the acclaimed creative team of Peter David, Paul Ryan, and Ron Wagner — a Copper Age debut that planted this Marvel figure squarely in the thick of some seriously heavy-hitting company. With Thor, Captain Marvel, Iron Man, and the Hulk himself sharing those pages, Brutus clearly wasn't rubbing elbows with the B-list. Though appearances in the catalog are select, the character earns a spot in Marvel's All-New Official Handbook — a mark of genuine universe significance — and one of those issues carries key-issue status for collectors. A compact but intriguing corner of the Marvel tapestry, Brutus rewards the dedicated fan who loves hunting down the hidden connective tissue of the universe.
