Character History

Powers and Abilities

  • Burn Blacker (バーンブラッカー Bān Burakkā): Mecha Smog Jouki can generate black flames from the Jouki Jaws that can damage even the Mashins, causing them to crack.
  • Strength: As the Crystalia Royal Train, Smog Jouki's power is high in combat and is one of the strongest machines of the Crystalia Kingdom, able to easily overwhelm Kiramaizin.
  • Laser Vision: In its train form, Mashin Jouki can fire purple laser beams from its red eyes.
  • Rift Creation: In its train form, Mashin Jouki can create a portal to travel from Earth to Yodonheim and vice versa.


  • Jouki Jaws (ジョーキージョー Jōkī Jō): Smog Jouki has powerful jaws.
  • Jouki Chainsaw (ジョーキーチェーンソー Jōkī Chēnsō): It has a chainsaw blade at the end of its tail.


  • Mecha Smog Jouki is the second Mashin after Mashin Fire to have three different forms, and one of which is based on an animal (In this case, a dinosaur).
    • Unlike Fire though, Jouki is capable of transforming into all 3 of its forms in a single transformation while Fire's 3rd form is actually separate from his main and stone form.
  • Its roar resembles a train whistle.
  • Mashin Jouki is the first onscreen Mashin to not have its alternate forms (with the exception of King Express) given by Juru.
  • Smog Jouki bears a striking resemblance to GoZyuRex.
  • Transforming into a train and traveling through portals makes it similar to the DenLinerIcon-crosswiki.png in Kamen Rider Den-OIcon-crosswiki.png.
  • Smog Jouki's Burn Blacker attack also resembles KillerOh's Bakuryuu Hissatsu : Death Combustion attack, with the difference being Burn Blacker was fired from its mouth, while KillerOh's Death Combustion was fired from its eyes.
