The Doublas M2 resembles a bipedal dinosaur with two horned heads and sharp claws, the navel area exposes three pairs of missiles.
Abilities and EquipmentEdit
The Doublas' heads can fire heat beams from the mouth area 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. The missiles on the abdomen could also be used to attack enemies, but were never used.
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 coil its heads around the Mazinger but it uses its Rocket punch to smash through Doublas chest and then as it goes back round it goes through the back of the neck of one of the heads ripping it off and ultimately destroying the beast.
- 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.
