Like many people, when I first heard about Megas, I was skeptical. I have never been a huge fan of giant robot shows (Voltron, Gundam W, Big O, and G Gundam being the exceptions) so I figured this would be nothing special.
Boy, was I ever wrong when I finally started watching the show.
Megas XLR is about a super robot from the future built by the destructive race known as the Glorft. With their next target being Earth, a human girl named Kiva steals the robot and sends it back in time. It's found in a junkyard in Jersey City by a slacker/gamer/anime fan/wrestling fan/gearhead named Coop and his girl-obsessed sidekick Jamie. Coop completely rebuilds the robot, using his car and various video game controls to pilot it. When Kiva attempts to reclaim Megas, she finds that she can't even pilot it anymore! Kiva then recruits Coop and Jamie to help her fight the Glorft, who have also traveled back in time to reclaim Megas.
The show parodies nearly everything from the 1980's to the present, be it movies, anime, video games, or whatever else the creators think of that day. The blend of action, comedy, and even some serious moments cause the show to be downright entertaining on nearly every level. If you have not watched Megas XLR yet, I advise you to give the show a try.
