And last but certainly not least, their mecha! The Monstranger's individual mecha are called DaiMons, from "dai" meaning big/great, plus mon from monster, and a play on the word demon.

- KowaiOh, the combined robo of the initial three Monstrangers, it's built slimmer and more flexible than most combined robos. Its arsenal includes a sword formed from the Cobra DaiMon's tail and a sonic screech fired from its chest.
- Bat DaiMon, Drack's personal mecha, it forms KowaiOh's head and chest.
- Cobra DaiMon, Cleo's personal mecha, it forms KowaiOh's arms, back and sword.
- Gorilla DaiMon, Sparky's personal mecha, it forms KowaiOh's legs and lower body.
KowaiOh can also equip one of the later Monstrangers' mecha in place of its right arm to gain a new weapon. In these forms, the sword arm moves to the back and acts as a scarf-like decoration.
- Wolf DaiMon, Canis's personal mecha, it forms an arm with large claws, upgrading the combination into Howl KowaiOh.
- Shark DaiMon, Mirage's personal mecha, it forms an arm with a built-in crossbow, upgrading the combination into Splash KowaiOh.

- Daikaiju KowaiOh, the combined robo of all five Monstrangers' DaiMons and Gigant Webster. The Bat and Gorilla DaiMons keep the same positions, but the Cobra moves to reinforce the legs, while Gigant Webster forms the back and shoulders along with a new helmet, with the Wolf and Shark each forming an arm. It can use both the claws and the crossbow, or combine them into a greatsword called Kowai Scimitar.

- Armored Hunter, Hikaru's personal mecha piloted with TA.I.yo's help, it can transform between the humanoid Battle Mode armed with a heavy cannon, and the supercar Pursuit Mode powered by a rocket engine. In Battle Mode it can equip the Wolf or Shark DaiMons onto its right arm to form Howl Hunter or Splash Hunter, and after being severely damaged, it's rebuilt and upgraded into Shining Armored Hunter.
