General Holter has his own understanding of what a union of galactic civilizations should look like. The problem is that his vision isn't shared by the rest of the leads of these civilizations, mainly because what he speaks of as a union sounds more like an army at his mercy for most. Therefore, if he wants to make his project come true, he'll have to do it by subjugating all those galactic civilizations by force.
Fortunately for him, now he has a starting point called Astronite, a resource that has allowed him to transform into a more powerful self, Brigadier Holter! Those unruly civilizations will have more trouble being disobedient to him now.
Brigadier Holter is a Metal and Dark Attacker with Double Damage, Shield Removal, and Nanovirus abilities.
