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.
Living Brain later appeared as a member of the Sinister Six when they fought the Superior Spider-Man. Following this, he has it delivered to Horizon Labs, where its reprogrammed to serve as his new lab assistant.
Living Brain later preps Otto's lab for a "Parker-Ectomy."
When Spider-Island II is attacked by the Goblin Underground, the Superior Spider-Man gets Living Brain out and rides it away from Spider-Island II while evading the pursuers from the Goblin Underground. The Superior Spider-Man later uses Living Brain to help fight Monster (the Goblin form of Carlie Cooper).
The Living Brain could think and reason faster than any human being and could learn and adapt its behavior. The Living Brain had ball bearing rollers for feet and had pincers for hands. It could spins it's arms and body like a top.
