Tyger Pax

Tyger Pax is a location found on the Cybertron depcited in the 2007 movie's continuity. It is both a battleground and a key feature to a strategy devised by Optimus Prime and it was made historic for several reasons: 1, Many Autobots gave their lives to ensure the plan worked. 2, It was the encounter that served as bait to distract Megatron as the Allspark was launched into space. It was the last time he was seen by any Transformer. 3, It is where Bumblebee was made a hero, distracting Megatron just long enough. The cost was his own voice box.
