Goupemon Legion Mode

The result of Goupemon absorbing the data of all of his soldiers, becoming no more than fuel for his dark powers.

In this form, his body is entirely self-sufficient, no longer needing dark energy to survive - instead, that dark energy is constantly produced by the absorbed data, through unknown means, providing a steady stream that's more than enough to boost his stamina to the maximum.

His power, agility and even his intellect are greatly increased, to the point that his dark influence on other Digimon can be effective regardless of their Attribute, with just his gaze and his voice, now joined by the lifeless voices of all the Digimon that he has absorbed.

His ability to teleport by entering one solid object's shadow and coming out of another is now limitless, since everywhere he goes, everything will be instantly shrouded in darkness.

The distortion in spacetime is such that permanent electric storms surround him all the time, and any further disturbance in the veil between dimensions will easily rip it apart, even bypassing the protective seal placed on the Digital World in December 2002.
