On the trip, a trainer confronted Liam, wanting to battle him. The trainer boasted about how he was going to beat me with his 'super powerful' Pokemon. He called out a Rattata. Liam felt bad about this. Unless this Rattata was absurdly strong, any Pokemon Liam has on him would leave it in critical condition. Liam sent out Croconaw. A single Power Up Punch  KO'd the Rattata.
