Dr. Snodgrass

A Marvel supporting player with roots in the Copper Age, Dr. Snodgrass first stepped into the X-Men's world in 1989 courtesy of the legendary creative team of Chris Claremont and Marc Silvestri — as strong a debut pedigree as the era had to offer. This is a character who keeps distinguished company, sharing pages with luminaries like Storm and Alison Blaire across titles including The Uncanny X-Men and Wolverine and Jubilee: Curse of the Mutants. What's quietly remarkable is the staying power: a presence stretching across roughly 35 years, from the Copper Age all the way to 2024, is no small feat for a figure with a modest appearance count. For the dedicated completist, Dr. Snodgrass is one of those understated threads woven into the rich fabric of X-Men history — blink and you might miss them, but they're genuinely there.
