Brain

Few comic companions are as quietly essential as Brain, the canine hero who made his four-color debut in Marvel UK's Inspector Gadget Annual #1986 (1985), right in the thick of the Bronze Age. Across a compact but charming run through the late '80s, Brain shares the page with the bumbling Inspector Gadget himself, the resourceful Penny, Mad Cat, and Chief Quimby — distinguished company for any character. With appearances spread across the Inspector Gadget series and its annuals, Brain may have a modest catalog footprint, but for fans of Marvel UK's licensed adventures of this era, tracking down these issues is a genuine treat.
