Maguma taishi

This is one of those pre-power rangers shows that Mr. Turner got the bright idea of bringing over for the american kids. This show is a real blur to me, but I do remember liking it ALOT! There were 3 robots, a big golden one (about 50ft) his wife, who was normal height (go figure that one out) and their son who was the generic best friend of the little boy who would summon them in times of danger. All of them transformed into planes and fought the big monster aliens.

this show was kewl, Turner was a genius at one time

A wacky fun TV series which beat Ultraman to the air as the first color tokusatsu (special effects) series. Osamu Tezuka is more famous for Astroboy but I grew up watching Space Giants every day after school as a kid. The series featured a family of three living robots: Magma, the title character, his wife Mol and son Gam. They were probably the first ever "transformers". They befriend a boy named Mamoru Murakami and gifted him with a supersonic whistle with which he could summon them if there was any trouble. As you can imagine, he seemed to find a lot of trouble.

In the US version the character names were changed to DIFFERENT Japanese names. Magma became Goldar, Mol was Silvar and Mamoru was Miko. Each of the characters had different powers. Goldar could shoot rockets from his chest and become giant to battle the monsters when needed.

The series was called "Monsters from Space" (or the Spanish equivalent) and I vividly remember watching it on Spanish television as a child.
