Very little is known of Mongoose’s past, before he came to New York City. He was smuggled out of his country of origin by Baron Zemo and the Masters of Evil. He was apparently supposed to join the Masters of Evil on their assault on the Avengers Mansion. The Absorbing Man and Titania, in disguise, were supposed to pick him up at the airport, but they became involved in a battle with Spiderman. Mongoose, now that he was in America, decided to forget about the Masters of Evil and set out on his own.
Mongoose was next seen attacking Thor, who was at a construction site in his civilian identity. Apparently he had been hired by someone to kill Thor, for an unknown reason. The Mongoose, using his cellsmograph, had tracked Thor down while he was in his Sigurd Jarlson identity. Spiderman intervened, giving Jarlson enough time to get his hammer and turn into Thor.
Spiderman and Thor fought Mon goose to a stand still, but Mongoose escaped after creating a diversion. Mongoose broke the support beams holding up the building where they were fighting. Fearing for the lives of the construction workers on the building, Thor held up the building long enough for Spiderman to fashion some temporary support so it wouldn’t collapse.
The current location of Mongoose is unknown, though he is probably still somewhere in New York City.
