Fenris

Debuting in 1989's The Mutant Misadventures of Cloak and Dagger #8, Fenris is a Marvel villain who emerged right at the heart of the Copper Age, when the X-Men corner of the Marvel Universe was crackling with dangerous new threats. With a publication history stretching across nearly four decades, this character has proven surprisingly durable for a figure with a relatively focused appearance count — a testament to the impression Fenris leaves whenever they turn up. The company Fenris keeps is impressively formidable: Wolverine, Beast, Emma Frost, and Warren Worthington III are among those sharing the page, placing this villain squarely in the thick of mutant-driven drama. For collectors hunting through Generation X back issues or diving into the underappreciated Mutant Misadventures run, Fenris is one of those rewarding discoveries that rewards the deep dig.
