Relf
Relf made their entrance in the pages of The Savage Dragon / Destroyer Duck #1 in 1996 — a Copper/Modern Age debut that already signals something delightfully offbeat about this character's comics pedigree, brought to life by the legendary Steve Gerber and Chris Marrinan. With only three catalog appearances, Relf is a rare find, and the fact that one of them carries key-issue status makes tracking them down genuinely worthwhile for the dedicated collector. Their adventures unfold in some eclectic company — sharing pages with the likes of Spider-Man, Peter Parker, and Princess Python — and their presence in the All-New Official Handbook of the Marvel Universe A to Z confirms Marvel considered them worth enshrining in canon. Small in footprint but rich in curiosity value, Relf is exactly the kind of hidden corner of the Marvel universe that rewards the fan willing to dig a little deeper.
