Due to my obsessive-compulsive need for the game to be as "canon" as possible, I use whatever the default name is (Blue, Silver, Barry, and Hugh). The same rule applies for the player characters, except in the case of Hilbert/Hilda because I think that those names are disgustingly bad (the former more so than the latter; Hilda's alright, but I still don't think it fits). For those two, I tend to use Black/Blair/Touya and White/Whitlea/Touko, respectively.
