Mechalong is Mandra's mecha and one of P.H.O.S.A.K.'s main weapons.
To combat the kaiju threat, P.H.O.S.A.K. specially trained warriors to take down the monsters. However, the daikaiju grew larger and larger, until they were a huge challenge for soldiers to defeat. P.H.O.S.A.K. created a robot, Mechalong, to defeat the more powerful kaiju.
Later on, P.H.O.S.A.K. allied with some of Earth's kaiju that aid Humanity, hoping to defeat the ones trying to destroy humanity. Mechalong now sometimes fights alongside the benevolent kaiju.
Mechalong, being a mecha, has no personality of its own. However, when used by its owner, Mandra, his battle tactics and behavior resemble that of its controller.
