With Xia You there, he naturally would not let Kenta fight alone.
In fact, Xia You and Team Rocket had long been bitter enemies, each eager to be rid of the other. Unless these people suddenly found some kindness in their hearts, turned over a new leaf, and did something good for the people of this world, he would take them on whenever he saw them.
