There are two different versions of the Octobots, the main one is a little metal ball with eight legs, which are controlled mentally by Doctor Octopus via a remote control. They can also be used to attack, to perform different tasks and attached to a person, they can make him/her obey its orders.
The other type of octobot is a giant metallic robot, which can be used to attack huge constructions.
Spider-Man refits all the Octobots confiscated from Doctor Octopus and kept in the New York Police Precinct to carry an antidote able to reverse the mutations turning all the New York population into Man-Spiders, he humorously renames them his own "Spider-Slayers".
