Mongoose

Mongoose is a fictional character, a comic book supervillain from the Marvel Comics universe. Apparently, Mongoose was a real mongoose before his powers were genetically engineered by the High Evolutionary to serve as his agent. At one point, the Mongoose arrives in New York where he is invited by Baron Zemo II to join his Masters of Evil. Mongoose later battles both Spider-Man and Thor, and this confrontation eventually causes Thor and Mongoose to become mortal enemies. After his first defeat at the hands of Thor, Mongoose flees. During his escape, he causes a fall of girders which injures Erik Masterson, better known as Thunderstrike. In a later plot against Thor, Mongoose teams up with Quicksand and Count Tagar to obtain cell samples...
