Swarm (real name Michael Tan) is a replicating nano-bot behemoth, and a former employee of Stark Industries.


Michael Tan is a disgruntled employee of Tony Stark who develops in a swarm of self-replicating nanobots after his projects were turned down by Tony Stark and ended up fired. Michael activates his device and scatters his molecules vowing that Tony Stark will regret this.

Michael ends up assuming his "Swarm" form where he had replicated the Spider-Tracer that Spider-Man was perfecting into attacking Iron Man and Spider-Man. Iron Man and Spider-Man eventually finds out that Michael is now Swarm. Iron Man contained parts of his different armors to help Spider-Man defeat Swarm as they wonder how to get Michael out of the Spider-Tracers. Swarm then splits into two to attack Spider-Man and Iron Man until he combines again. Spider-Man uses his Spider-Tracer's interface in order to amplify the frequency with the Arc Reactor as he is thrown into Swarm by Iron Man. Upon the frequency being activated, Swarm is neutralized as Iron Man has confiscated the Spider-Tracers back together in order to put Michael back together again.[1]

In the episode "Sandman Returns", Swarm attacks a S.H.I.E.L.D. facility to assimilate the technology, resulting in a fight with Spider-Man and Sandman. Swarm targets Sandman's containment suit which forces Spider-Man to get the containment suit off Sandman. Sandman then pummels Swarm into submission.

In the episode "HYDRA Attacks" Pt. 1, Doctor Octopus, upon his capture, unleashes one of his miniature Octobots into Swarm's cell to have his nanites recreate the S.H.I.E.L.D. Tri-Carrier into HYDRA Island. This causes Swarm to explode, killing him in the process.
