Burke

Debuting in the pages of The Uncanny X-Men #282 in 1991 — a landmark Copper Age issue brought to life by the dynamic creative team of Whilce Portacio and John Byrne — Burke is one of Marvel's quietly persistent background figures, surfacing across nearly three decades of mutant-universe storytelling. With appearances spread across Uncanny X-Men, X-Force, and collected editions, Burke keeps genuinely exciting company, sharing pages with the likes of Domino, Bobby Drake, and Boom-Boom. Five catalog appearances may be a modest tally, but the fact that one of them carries key-issue status speaks to the significance of the moment Burke first stepped onto the Marvel stage — and for devoted completists tracing the full tapestry of the X-Men's modern era, that's more than enough reason to take notice.
