Mandora have come to Earth and infested the planet with his alien minions and also revived ancient beasts from Earth's past. Unable to fight back the invasion, the Earthlings were forced to move to the bottom of the sea, leaving their weapons protected in hangars on the surface, awaiting for when the time came for them to be able to fight Mandora and its minions.
After a few years, the Earthlings formed the Terra Cresta organization with the objective to retake control of Earth, having successfully developed the Wing Gamiver airship which they send to the surface to fight against the invaders. The Wing Gamiver fights Mandora's monsters and recovers the weapons on the hangars, using them to power itself up and fight Mandora himself, who ends up defeated and forced to retreat.

Terra Cresta 3D
This is a remake of the original Terra Cresta. During the boss fight the POV shifts from 2.5D to 3D. So Players will engage Mandora and other bosses in 3D POV. But unlike the first two series, This game only features aerial characters.
Mandra makes appearance in another video game from Nichibutsu named Sky Robo (Fight! Big Fighter in Japanese) not as a boss but several mid-level minions. As it turns out, Mandora has been nothing more than an underling of the bigger bad that calls itself 'Empire of the Dark'.
