Brain

Brain is the highly intelligent secret agent dog belonging to Penny, niece of the bumbling Inspector Gadget. Despite appearing to be an ordinary pet, Brain covertly assists Penny in foiling the schemes of the villainous organization MAD, often in disguise.

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.
