Luke

A quiet but intriguing presence in Marvel's Ultimate Universe, Luke made his debut in Ultimate X-Men #15 in 2007, brought to life by the acclaimed team of Robert Kirkman and Salvador Larroca during the Modern Age. His brief but notable run places him in electrifying company — sharing pages with the likes of Logan, Ororo Munroe, Bobby Drake, and Alison Blaire across Ultimate X-Men and the cataclysmic Ultimatum crossover. With only a handful of appearances, Luke is one of those intriguing corner-of-the-universe figures that dedicated Ultimate Universe completists will want to track down.
