Yeah, Team Rocket's introduction speech probably sent all the Jagers into fits of laughter. The Heterodyne knows better and after the first try, Team Rocket never bothers them again. One day after Team Heterodyne beats another gym, someone stands up and accuses them of cheating. "Those aren't real Pokemon!" Said person gets hustled out of there by security while everyone else apologizes to the Heterodyne.
The jagers have a great deal of fun acting very offended at the accusation. The Heterodyne, in the middle of a chorus of offended “Jager jager JAGER!"s, wonders if bringing the jagers along was really worth it.
