Grandeo

Grandeo is a dark living planet in the form of a giant asteroid composed of a large mass of Minus Energy that was brought by Grand Witch Grandiene from the depths of space in order to impact it against the earth to be able to absorb it and thus recover its complete form.

To hide any knowledge on the part of GoGoFive of the arrival of the asteroid, Grandiene orders his son Dragon Dark King Salamander to inhibit his communication network and keep Grandeo's existence a secret. Salamander then orders his Beast Psyma Papetongu to attack the Astronomy Institute to control and manipulate the staff with their vines and inform GoGoFive that no asteroid had been seen. However, Sayuri Iwakura, an astronomer and friend of the friend school of Nagare Tatsumi (GoBlue) who had been the first to discover the asteroid getaway from the place with the information about Grandeo stored on a CD. Despite Salamander's efforts to destroy the disk, Grandeo's information reached GoGoFive.

With the knowledge of Grandeo, GoGoFive used Max Victory Robo to destroy the asteroid with the Max Nova, but Salamander using the power of the Dark King's Star created a dark energy field around the fuse to cut off its solar energy and prevent it from destroying the asteroid Professor Tatsumi then uses his new creations the Mars Machines, a quintet of five spacecraft for the GoGoFive to travel into space and destroy the asteroid.

Once inside the space, the GoGoFive with the Mars Machine deploy from the GoLine to then form Beetle Mars, which assembles the asteroid and begins to place explosives to destroy it. However, before they could take off, Grandeo comes alive and grabs Beetle Mars and GoGoFive. To escape, the GoGoFive transform Beetle Mars into Mars Victory, which plunges its spear into the ground and detonates the explosives, destroying Grandeo and escaping just in time for the explosion.
