Rainbow Squadron Robin

A distant planet, far off in space named Palta is facing the doom of extinction. There are only two years left until their ultimate demise. Palta looks to Earth to cultivate resources and begins attacking it in hopes of taking over. Earth turns to a boy named Robin, who owns many robots. Robin's father is an alien from Palta who was sent to Earth as a spy, but fell in love with a human. Robin's father, Dr. Polto, and mother, Sumiko, are forcibly taken back to Palta, but his father makes numerous robots for him before they leave. The robots are named Lili, Wolf, Benkei, Pegasus, Professor, and Bell, and all have unique superpowers of sorts. (Source: Wikipedia)
