Yatsude Saburo

Yatsude Saburou 八手三郎

This is probably not an actual person, but a pen name for a group of people. In Japan, his name is usually pronounced Yatsude Saburo, but there are times like in the Power Rangers where he's credited as Saburo Hatte. This pen name has existed as far back as the 70s (even being included on the Japanese Spiderman series).

Trivia

In Kamen Rider Decade episodes 24 and 25, which is a crossover between Kamen Rider Decade and Samurai Sentai Shinkenger, Yatsude Saburou was not displayed after Ishinomori Shoutarou in the original creator (during opening theme) before he was displayed in both Super Hero Taisen and the net movie Super Hero Taihen.
In Hikounin Sentai AkibaRanger episode 12, he is the main antagonist, since the story had become a meta story about the characters in the show fighting off the creator trying to end the series.
In Jyuohger's Super Doubutsu Taisen 03, Hatte Saburo appears as a stinky half man in a box. The Jyuoh girls touch him as part of their test of courage.
Name means "Eight hands, three sons".
