It didn't take a lot of time for Allen, Realius, John, and Axel to decide which country they would take care of first.
Allen decided to let his artificial warriors eradicate the aliens in Japan. Allen himself would take care of the aliens in the Philippines since he felt at home there. After all, Allen was half Filipino since his mother was a Filipino while his father was an American.
That was why Allen decided to eradicate the aliens in the Philippines and America by himself.
As for Axel, he decided to go to England and Canada while John would go to Australia and India to purge all aliens there.
As for Realius, he would use his reality manipulation to target all of the aliens in the remaining countries. And since he didn't want too much trouble such as causing a reality paradox, he decided to not erase the existence of those aliens and just kill all of them.
