Never really stuck to a theme, although I do have perma nicknames for some Pokemon. If I ever have an Ampharos it is to be called Cleopatra. If I ever have a Nidoking, it is to be named Scaramanga. If I pack a fire type with me, which I usually don't, I call it Burnace, which I wince at now but, meh.
One time I named a Grimer Valdez and made it fight a Wingull. I felt remorse for my actions.
