Colossusus

A pint-sized powerhouse of the Copper Age, Colossusus burst onto the scene in 1988's X-Men Annual #12 under the imaginative hands of Chris Claremont and Art Adams — and if that creative pedigree and the company this character keeps (Sugah, Wolvie, Li'l Longshot, and the dimension-hopping showman Mojo) tells you anything, it's that Colossusus inhabits the wonderfully weird, satirical corner of the Marvel Universe where the X-Babies roam. With appearances anchored in Excalibur: Mojo Mayhem and X-Babies: Stars Reborn, this is a character born from Marvel's gleefully self-aware, anything-goes era of cosmic absurdity. Rare in the catalog with only four recorded appearances, Colossusus is a genuine curiosity for collectors who love the stranger, more playful edges of X-Men lore.
