History: When Crosswise needed help, he went to find Evac. Crosswise was followed by Sideways, but Evac had already sensed this and attacked Sideways. They then went to defeat Starscream, but broke off the attack when Optimus Prime blocked a blast meant for them. Evac went alone to retrieve Earth's Cyber Planet Key so the Autobots could leave Earth. On his way back he was attacked by Starscream, but managed to return. Starscream managed to steal the Key from him and went on to steal the Omega Lock as well.

Official character text from packaging... 
EVAC loves flying on Earth almost as much as he loved soaring over the epic skylines of CYBERTRON. He's been in hiding on Earth since guardianship of the Planet Key was passed on to him millions of years ago. He feels a keen affection for the people of Earth, whose history he has observed from its very beginnings. It frustrates him that the TRANSFORMERS must keep their presence on Earth a secret, because he recognizes the potential value of the humans as allies. Courageous, determined and gentle, EVAC avoids fighting when he can, but if forced into combat, he can be a very tough opponent. He is dedicated to the protection of other life in all its forms.

Cyber Key Code: v49u
Evac is commander of the hidden Earth Cyber Planet key and he and his partner Crosswise have been hiding here on Earth for hundreds of years! Evac has changed his vehicle mode at least a dozen times over the years so he wouldn't be found. He has taken the form of a bi-plane, a small army jet, a super-fast stealth jet, a propeller plane, a blimp and at lest 14 different types of helicopters! Talk about being a robot in disguise!

Earth Planet: Now under the protection of Jetfire, Scattorshot and the other Autobots, Earth is a front line in the struggle for domination of the universe. With their home world of Cybertron under threat by the super giant black hole left by the destruction of Unicron, the Autobots and the Decepticons have secretly moved their bases of operation to Earth. 

With the help of Vector Prime, and a few humans that have discovered their presence on Earth, the Autobots must race against time and battle an unbelievably more powerful Megatron and his new army of Deceptions to recover the lost Planet keys, ancient artifacts missing for eons. What few realize is that this little planet called Earth has played a vital role in the history of Cybertron for millions of years.
