"Number 6: Chronomaly Machu Mach!!!"
III's hidden trump card—his strongest Number. The instant the Dieguang Network formed, it was as though the number "Number 6" burned in the void. The distant horizon began to warp, and a golden pillar of light piercing sea and sky shot straight into the heavens. Within it, the giant's outline gradually emerged: first its knees covered in coral and seaweed, then its thick thighs flowing with magma. The lines of every muscle resembled dried riverbeds.
When the giant fully rose, it seemed to blot out half the sky. Above its waist rested an entire miniature continent: to the north were mountains blanketed in primeval forests, with pterosaur-like shadows circling among the treetops; to the south was what looked like a volcano ready to erupt at any moment, orange-red lava flowing through rocky ravines and onto its bronze-colored arms. The magma dripped through its fingers, instantly evaporating into hundred-meter columns of steam when it hit the sea.
The hundred-meter-tall giant stood like a pillar holding up the heavens. Even throughout the World of GX, monsters this massive were extremely rare.

"It's so huge!"
Even Judai, who had seen plenty in his time, was stunned.
Judging by its size and appearance alone, it could practically rival a god—perhaps even surpass one.
Still, that was a feature of the ZEXAL Dimension. Giant monsters were more common there than in any of the other generations, and Machu Mach was not even close to the biggest.
