First Inter Galactic Peace Conference

They must not have high expectations for the peace conference if they are already anticipating the need for a second one.

The First Inter Galactic Peace Conference was held on Cybertron. Delegates from around the galaxy gathered to discuss peace. The delegates appeared to be all organic humanoids. The Decepticons were not in attendance.

The conference was threatened with destruction when Cyclonus set the Autobot Storage Asteroid on a collision course with Cybertron. While Ultra Magnus was fighting with Cyclonus, Wheelie snuck into the control room where the large red "Auto Destrut Sequences" button was kept and pressed it. The Autobots escaped on Sky Lynx before the asteroid was destroyed. The conference was saved, but a wealth of Autobot knowledge was lost, including, most unfortunately, the date of Ultra Magnus's birthday. Surprise Party
