Teletraan-1 was built by the High Council during the Golden Age of Cybertron and was maintained by the Hall of Records. During the civil war, Megatron sought the Plasma Energy Chamber to poison Cybertron's core with Dark Energon. Entering through an energy tunnel from Kalis that was barely spacious enough to fit his largest gladiators, Megatron fought Sentinel Prime for access. Retrieving the Code Key of Justice from Sentinel's body, Megatron opened Teletraan-1, but the computer awoke Omega Supreme and ordered him to fly the Chamber to safety. Sadly, the Decepticons shot down Omega and still corrupted the core.
When the Autobots left Cybertron on the Ark, Alpha Trion had the computer moved on board, explaining it would give them the knowledge they sought in his stead.
Teletraan-1 was disassembled within Autobot City and reassembled on board the Ark before it departed Cybertron. Various nodes across Cybertron offered weapons and systems upgrades to either Autobots or Decepticons, as it was blind to allegiances due to a flaw in its programming.
- Teletraan-1 is also the name of Transformers: War for Cybertron and Transformers: Fall of Cybertron's in-game menu.
- In Grimlock's Fall of Cybertron gameplay segments, Teletraan-1 upgrade nodes can be found in several places, but will inform the Dinobot that his body type is not compatible with the upgrades. Amusingly, the nodes in these stages are destructible, so Grimlock can smash them in frustration if he wants to.
