Boomer brought them to his gym. Mike was feeling generous and let Carson battle him first. Boomer said that only 2 people were allowed in the gym because the gym was newly renovated and some parts are still sensitive. Mike and Georgia were forced to stay outside in the hot town. They were walking around the town until they saw a Team Boom Grunt harassing a 6-year-old girl. The Team Boom Grunt wanted to steal her little Jigglypuff. Mike ran up to the Team Boom Grunt and demanded a battle!
Mike sent out Litwick and the Team Boom Grunt sent out a Tirtouga. Litwick used an Ember but just faded off on the Tirtouga. Tirtouga used a Water gun which did some damage, Litwick came back with an astonish, then Tirtouga used Rock blast, which knocked back Litwick, then Litwick started to have a blue aura, it was evolving! Litwick had evolved into a Lampent, and it had learned Shadow Ball. Lampent was able to defeat the Tirtouga with a Shadow Ball.
The Team Boom Grunt left in defeat. The 6-year-old thanked Mike and gave him a big hug, she then ran off in the distance. Then, a Riolu who was watching Mike in the background came up to him demanded that he joined a strong team like Mike's. Mike brought the Pokeball up to Riolu and it entered. Mike had got his 4th team of his Master Team. Georgia said that Boomer was a rock-type specialist, so Riolu would have an advantage. Mike went to Route 11 to train with Riolu. An hour later, Georgia came with Carson and found Mike and Riolu training.
Carson said that he had defeated Boomer. Mike congratulated him and now it was his time to battle Boomer. Carson congratulated Mike back for catching a Riolu. Mike went to enter the gym and went for his 4th badge...
