Mongoose

A genetically engineered mongoose created by the High Evolutionary, Mongoose was granted humanoid form and enhanced physical abilities — including superhuman speed and agility — and has repeatedly clashed with Thor and Spider-Man as a mercenary agent.

A creature of the Copper Age with claws in two worlds, Mongoose debuted in The Amazing Spider-Man #283 in 1986, courtesy of the legendary team of Tom DeFalco and Ron Frenz, before finding a natural home in the thunder and mythology of Thor and even the wild courtroom corridors of She-Hulk. Affiliated with the Asgardian Gods and the Warriors Three, this Marvel villain keeps genuinely elite company — sharing pages with Thor Odinson, Hogun, Volstagg, and Fandral — which tells you everything about the cosmic weight of the world Mongoose inhabits. A character who crosses from street-level New York to Asgardian grandeur and back again over a twenty-plus-year publishing run is one worth tracking down, and with appearances spread across three marquee titles, there are some wonderfully eclectic back-issue hunts in store for the curious collector.
