Ariel

Ariel is a mysterious alien mutant who joined the offbeat X-Men-adjacent group the Fallen Angels. She possesses the ability to create teleportational doorways between locations, and her true motives for befriending the young runaways she encounters remain deliberately ambiguous.

Stepping out of the Copper Age with a debut in Fallen Angels #2 (1987), Ariel is one of Marvel's more intriguing cult figures — introduced by the creative team of Jo Duffy, Kerry Gammill, and Tom Palmer in a series that carved out its own offbeat corner of the X-Men universe. Over a publishing span stretching all the way to 2021, this character has kept genuinely fascinating company, sharing pages with the likes of Boom-Boom, Warlock, Roberto Da Costa, and Gomi — a roster that signals just how wonderfully unconventional Ariel's world has always been. With 14 catalog appearances including a collector-significant key issue, Ariel is the kind of hidden gem that rewards the dedicated fan willing to dig into Marvel's deeper cuts.
