Choriki Robo Galatt

 is a comedy-science fiction anime series by Sunrise. It is also known as "Super Robot Galatt" and "Change Robo Galatt". 
It consists of 25 episodes and was originally broadcast on the TV Asahi network as well as some Fuji TV, Nippon TV and TBS affiliate stations. Sunrise produced the series with the cooperation of Asahi network affiliate Nagoya TV. It was the follow-up series to "Ginga Hyōryū Vifam", using many of the same production staff (including Toyoo Ashida as character designer and Kunio Okawara as mecha designer), and was made to purposely be lighter and less serious than its predecessor. The series was a debut role for both Katsuhiko Nakagawa (as Michael) and Yoshino Takamori (as Patti).
According to Jonathan Clements and Helen McCarthy's "The Anime Encyclopedia", the series spoofs the classical mecha genre, with the battles between robots serving as "a topic for gag and parody".
Plot.
The story takes place in a future version of Earth where war has been outlawed and owning weapons is forbidden. A galactic real estate syndicate arrives to carve the planet up into subdivisions. To combat the invasion, a genius inventor, Dr. Kiwi, recruits young Michael Marsh, his girlfriend Patti Pumpkin, and rich classmate Camille Cashmere Jr. as fighters by upgrading the kids' robot helpers (known as Janbu, Patigu and Kamigu respectively) into powerful robot fighters. Michael's robot sidekick Janbu becomes the titular Galatt. 
Much of the humor in the series comes from Dr. Kiwi's pedophilia, as he demonstrates an attraction to 13-year-old Patti. This subtext may be part of the reason the show was never sold internationally.
