>>13275640>Or at least go back when they saw this shit was going on?That all depends on how his plans unfurl.
He could either
1)Do a slow political takeover and pass some law that says that pokemon must stay in designated areas where he can easily detain or eliminate them.
2)Do a full scale take over. Depending on if he has the help of Colress or not this could be the easiest option as no one would be there to stop him from freezing all of Unova with Kyurem's power, that is if he has Kyurem. With this plan the fusion of the dragons can be a last resort.
Either way Ghetsis is an evil mastermind and would most likely find a way around that.
