The Living Brain is a robot that was an enemy of Spider-Man. By feeding the Living Brain all the available facts about Spider-Man, it might have been able to find out his secret identity.

It was created by I.C.M (International Computing Machines Corporation) and was exhibited at Peter Parker's high school. It was supposed to be the greatest computing machine ever built. It could answer any question which is fed to it, basing its answer on the vast storehouse of information which it possesses. Unlike a human brain, it never forgets a thing. Two technicians tried to steal it and use it to figure out horse race winners, elections, etc. When Mr. Petty of I.C.M. tries to stop them, one of the technicians bumps the control panel and the robot went on a rampage. Spider-Man was able to stop it by readjusting the Living Brain's controls and deactivating it.

Spider-Man later battled the Brain again, when a nerd sent it on a rampage to nail a bully.
