Doublas M2 (ダブラスM2) was one of the first Mechanical Beasts fought in Mazinger Z alongside the Garada K7. After their initial appearances, both the Doublas and Garada appeared in different media of the Mazinger franchise.


The Doublas M2 resembles a bipedal dinosaur with two horned heads and sharp claws, the navel area exposes three pairs of electrical emitters.

Abilities and EquipmentEdit

The Doublas' heads can fire heat beams to attack enemies and obstacles, the beams can also be combined for a more powerful blast of energy. Its necks can be extended certain distances to attack and restrain enemies using its heads as spearheads. At times, it even discharges electricity from the panel on its stomach.


The Garada K7 and Doublas M2 were sent by Baron Ashura to attack the Photon Power Laboratory. While both Mechanical Beasts managed to overpower the lab's defenses, the arrival of the Mazinger Z turned the tides, Doublas tries to attack the opposing robot but it's attacks can do nothing to it. As Mazinger Z fought against the Mechanical Beasts, Doublas M2 got into a grapple with Z. When Garada threw its scythe, Koji used the opportunity to cut one of Doublas' heads off. Koji then used the Koshiryoku Beam to ultimately destroy the Mechanical Beast in its weakened state.


  • Along with Garada, Doublas has had the most appearances out of every Mechanical Beast appearing in nearly every version of the Mazinger franchise.
  • His concept art design was later used for his Mazinkaiser counterpart.
