He first appeared during the Pokémon Tag Team tournament where he was partnered with Dawn. Conway is an incredibly intelligent trainer and often plans strategies ahead of time in order to make sure he has the upper hand in battle. He appears to have a crush on Dawn and often appears out of nowhere, startling Dawn in the process. The second time Conway meets Dawn, Ash and Brock he follows Dawn all the time, so everyone thinks that he still has a crush on her. He is said to be strange and random. During the Sinnoh League when he was about to face Ash he wasn't studying him, he was studying Tobias. He has a very similar appearance to Max.
Most of Conway's Pokémon were seen during the Sinnoh League.
Slowking was Conway's main Pokemon and was often seen outside its pokeball.
