Space Sheriff Sharivan is the second of Toei's Metal Heroes series, and the second of the Space Sheriff trilogy.
As told in an episode of his predecessor's show, forest patrolman Den Iga was attacked by a monster of the Makuu Empire and gravely injured. He is saved by Gavan, who sends him off to Planet Bird for treatment. Den returns the favor in the last episode when it's revealed, off screen, that he received Space Sheriff training from the Galactic Union Patrol and is now Sharivan!
Sometime after that, the evil Madou Empire, led by the evil Demon King Psycho, arises to conquer Earth. To defeat them, Sharivan and his sidekick Lilly must take action.
Space Sheriff Sharivan provides examples of the following tropes:
- Action Girl
- Lily becomes one starting from the second third of the series onward.
- Helen Bell is one as soon as she is introduced.
- By the Power of Grayskull!: "SEKISHA!"
- Cool Bike: Motosharin
- Cool Starship: Grand Birth
- Finishing Move: "SHARIVAN CRASH!" A powerful Laser Blade slash that can split the monster diagonally and cause them to explode.
- Fridge Horror: Unlike other tokusatsu monsters of the week created by Toei, the Space Sheriff trilogy's monsters of the week are outlandishly powerful in context with a rather horrific tone. Most of them never talk or emote, but still have human level intellect, much like a serial killer, and in addition to at least one melee weapon their standard powers include size changing, teleportation, invisibility, some bodily weapon, and shape shifting. Add Religious Horror for more atmospheric effect.
- Gag Haircut: General Gyrer has one, although his Badass Mustache balances it out.
- Human Aliens: The Madou has a few in their ranks, Makai Beasts usually have human disguises, the Iga Resistance qualifies, Billy and Helen Bell as well as their former commrades, and Den and his family are actually part alien, being descendants of people from the planet Iga who settled on Earth two thousand years prior to the events of the series.
- Humongous Mecha: Grand Birth transforms into the 400-some meter robot Battle Birth, making it a Transforming Mecha as well. Its arms are plasma cannons and each shoulder has a similar weapon called the Grand Buster.
- Laser Blade: Like in Gavan, it is the Trope Namer
- Meadow Run: A rather bizarre one caused by Reidar.
- Monsters of the Week: The Makai Beasts who can transform between two different faces. They also come with telekinesis.
- Morally Ambiguous Doctorate: Doctor Polter, somewhat subverted as she is sane.
- Names to Run Away from Really Fast
- Demon King Psycho, fitting since he often gives at least one Nightmare Sequence for his target(s) of the episode.
- In the last episode, Psycho Horror.
- Nature Lover: Den was originally a park ranger before becoming a space sheriff and continued to be one during the series, naturally this is part of his character.
- Ominous Pipe Organ: Often used when Demon King Psycho is on screen.
- Ray Gun: Sharivan's main weapon, the Crime Buster, which comes with various types of laser beams.
- Shinigami: Reidar as well as one of the Makai beasts.
- Space Police: It is in the title.
- Surreal Horror: Main motif of the Madou.
