  • Took a Level in Badass: Early episodes, he gets beat up easily each appearance he makes, Ryuuwon once just walked into his lair threatening information of out of him.

An ancient once-human adventurer who transfigured himself into a dragon after being betrayed by his comrades. He despises humanity, and wishes to create a world where only the truly worthy may survive. Often fights against Akashi, due to their similarities.

  • The Dragon: Literally. In respect to the trope, though, he's not a straight example (seeing as he works independently), but he's one of the stronger villains in combat, often takes to the battlefield himself and is the next to last villain to bite it.
  • Homage: His design is based on Daizyujin from Kyoryu Sentai Zyuranger.
  • Mook Maker: Is able to create his Jaryuu soldiers from samples of his own body.

  • Unexplained Recovery: Gets exploded in Task 29, but is back a few episodes later with no reactions.
  • Was Once a Man: used to be a human, and briefly turns back into one before being killed off.

Dark Shadow

A group of Japanese-based thieves who are out to make big bucks by stealing Preciouses. Consist of Maboroshi no Gekkou (owl), Kaze no Shizuka and Yami no Yaiba.

Maboroshi No Gekkou

  • Devil in Plain Sight: When the Boukengers actually meet him, justified since they haven't seen or even heard of him prior to that point.
  • Make My Monster Grow: Gekkou is the most reliable source of this trope with his 'Oogami Henge no Jutsu.
  • One-Winged Angel: During the only time he personally fights the Boukenger, turns into a huge, monstrous bird. However, he didn't do it on his own free will: Yaiba forced him to, and Gekkou was unable to controll himself in his monstrous form.
  • Orcus on His Throne

Yami no Yaiba

  • Arch-Enemy: Yaiba is this Masumi.
  • The Dragon
  • Dragon-in-Chief
  • Knight of Cerebus: Yaiba, the first completely serious villain we get in the series.
  • Token Evil Teammate: Gekkou and Shizuka can be sympathetic and look like 'just doing their job'. Yaiba is the only straight up villain as he is a darkness-worshipping guy who ends up betraying the whole team for the power of darkness.

Kaze no Shizuka


A group of Ashu demons out to make humans suffer and take over the human world. It has a whole army, but only two are in the world: Rei and Gai. They were quickly defeated but came back more powerful and mechanized when Gaja gave them the Godom Engine. They quickly broke out of Gaja's services and worked on their own. They're Eiji's Arch-Enemy.

  • Evil Counterpart: They were made into Questers by Gajah using research on the Boukenger's Parallel Engines. Their Quester forms and Swiss Army Weapon also look vaguely Rangerlike. And to top it off, they also use Humongous Mecha during each of their appearance, instead of going for human sized monsters that grow bigger upon defeat.
  • Evil Is Not a Toy: Gaja revives them with the Godom Engines, but didn't actually come up with a plan to control them.
  • Homage: To nearly all the mecha of Gosei Sentai Dairanger. Gai is Ryuuseioh, Rei is Won Tiger, Quester Gai is Dairenoh, Quester Rei is Kiba Daioh, and Hyoga is Daimugen.
  • Humongous Mecha: The Quester Robos, most of which were designed specifically to use a particular Precious.
  • Knight of Cerebus: Are treated as the biggest threat in the show and tend to be the toughest to fight ironically are the first to die.
  • Not Quite Dead: Their apparent status between being killed as Ashu and revived as Questers.
  • Offscreen Villain Dark Matter: Where do they keep getting those mecha?
  • Sealed Evil in a Can: Rei was trapped in a mirror, along with the rest of the Eastern Ashu, until Gai and Hyouga found a way to bring Rei back.
