Hayato is absolutely going. This is a personal fight for him. Ignoring what Gigas did to him personally, he won't stand for letting Gigas continuing to do to Sanctuary what they wanted to do to Caldera. He won't rest until he's punched that place to freedom. That said, he, like the other Calderans, are a lot less concerned about not taking life in this instance. Be prepared to see him do what has to be done for the mission.

Also he will come with a Taki. He will not be taking pokeballs, not because of issues with pokeballs but because he'd rather rely on his own two hands more than anything so he will just be taking his Marowak, Goro.

Eiji Will also probably be going because I've wanted to do something combative with him for a while and he might be close to evolving his final time SO THERE'S THAT. I've got no plans with him other than he'll be on the Union side of this and not want to kill anyone at all. Eiji is also of the no pokeball mind but because of Union reasons. He'll be taking Hina and his Glaceon, Yumi.
