Following on from Space Sheriff Gavan came the second installment of the Metal Hero series: Space Sheriff Sharivan.  Running from March 1983 through  until February 1984, Sharivan was a direct sequel to Gavan maintaining its continuity and assorted characters.

This continuity started in Space Sheriff Gavan,where Den Iga is attacked by a monster called Buffalo Doubler, member of the Space Mafia Makuu. Den is seriously injured in the attack when he is found by Gavan, who takes him to Planet Bird for medical assistance. Qom, leader of the Galactic Union Police, is impressed by Den’s courage.

Den returns in the final episode of Gavan, saving Gavan himself in his newly acquired form of Space Sheriff Sharivan during Gavan’s final battle.

After Don Horror is defeated, Sharivan is assigned to Earth and is partnered together with Lily from the planet Bird as he deals with the threat of the Madou Space Crime Syndicate on Earth.
