On Pearl I'm naming a lot of my Pokemon after composers; Ludwig the Turtwig, Johann the Buizel, etc. I want to name the Lake Trio Alnitak, Alnilam and Mintaka, after the three stars in Orion's belt, and I'm thinking of using names of artists for my White team.
Does anyone else use a specific theme when nicknaming their team? The possibilities are practically endless; capital cities, mountains (Everest the Arceus?), or even presidents (George for a Grass type!).
