Tyger Pax

Tyger Pax is a location on Cybertron in the Movie continuity family.

The lynchpin battle between the Autobots and Decepticons on Cybertron happened at Tyger Pax. It is both a battleground and a key feature to a strategy devised by Optimus Prime, wherein the All Spark would be blasted into space to remove it from Megatron's grasp.

The battle served as bait to distract Megatron as final preparations were made to launch the All Spark; it was the last time he was seen on Cybertron. Many Autobots gave their lives to ensure the plan worked.

It was here that Bumblebee became a hero. He and his squad held off Megatron just long enough for the Allspark to be launched; Megatron tore out Bumblebee's vocal box by way of retribution.
