In the year 3037, an attractive young scientist named Kiva has built a mecha robot called the Megas to go back in time to change the outcome of a war started two years prior by an invading by a race of cthulhu-looking aliens called the Glorft from invading Earth. Unfortunately for Kiva, the plan backfired and her robot was sent back to 1936 where it lay abandoned in a junkyard in New Jersey until 2004 when two late twenty-something slackers named Coop and Jamie made some cool modifications to the robot such as replacing the head with a hot rod, simplified the complicated futuristic controls with a steering wheel and a Playstation joystick, replacing the manual overide with a Dance-Dance-Revolution arcade machine, and painting the blue exterior with hot rod flame decals turning the robot into the Megas XLR. Kiva finds her robot in the past and to her chagrin finds that two dimwitted boys have overhauled her robot. To make matters worse, she can't go back to her time because Coop destroyed the robots time travel device without knowing what it was. However, Kiva is impressed with Coop's ability to pilot the Megas. Ironically, Coops piloting abilities, and his big stature, was from playing hours upon hours of playing video games.

During the first episode, Coop attacks the alien mechas with an energy weapon in its chest. This is, in fact, the tip of the Yamato from "Uchû senkan Yamato" (1974), firing its primary cannon.

Kiva:
I should have stayed in the future.
