Coil

Coil slithered onto the Marvel scene in 1999, born from the creative partnership of Chris Claremont and Salvador Larroca in the pages of Fantastic Four — a striking late-Modern Age debut that quickly drew this character into the orbit of some genuinely compelling company. With appearances spanning Fantastic Four, X-Men, and X-Men Universe, Coil moves through corners of the Marvel universe where heavy hitters like Kurt Wagner and Raven Darkhölme also tread, alongside enigmatic figures like Gyre, Helix, and Ringlet. It's a brief but intriguing footprint — the kind of rare, limited-appearance character that makes dedicated collectors and continuity enthusiasts sit up and take notice.
