Evac, also known as Live Prime, is dedicated to protecting life. Charged with guarding Earth's Cyber Planet Key untold centuries ago, Evac has watched humankind grow and evolve, and does what he can to help them while maintaining the existence of the Cybertron race a secret from them. It's a balancing act, but one he gets a real kick out of. He's tough but fair, steadfast but never overly rigid, and never panics. Evac and Crosswise are old friends, having hunted down the rogue Ancient Decepticons for the duration of their stay on Earth.
