Teletraan II

Following the destruction of supercomputer Teletraan I, the Autobots constructed its successor, Teletraan II. Able to be accessed with equal ease from both Autobot City on Earth and the Autobots' headquarters on Cybertron, Teletraan II takes on roles such as coming up with solutions to problems the Autobots encounter, recording Autobot activities for later analysis, and keeping educational files on both the Autobots and Decepticons. It likely has Sky Spy technology.

The Transformers cartoon
Teletraan II played back the battle between Metroplex and Trypticon several times over for Grimlock's amusement. When a request was made of Teletraan II to show the moment when Metroplex finished Trypticon "forever," the computer informed the Autobots that such was impossible, as that had never happened. Thus did the Autobots learn that Trypticon had not actually been destroyed, as they had previously believed to be the case. Thanks for waiting to tell them that after Trypticon had left.

When the Autobots on Cybertron started glitching, they consulted Teletraan II to find out the cause. The computer informed them that the new power generator was sending strange force waves up to the planet surface, causing the malfunctions, and suggested that the generator should be repaired or else they'd have to abandon the planet.

When Twincast received a message from Optimus Prime coming from deep space, Scamper linked him up to Teletraan II in order to display the message onscreen.
