Raoul: Piplup
Carlotta: Primarina
The Managers: Serperior and Armaldo
Madame Giry: Umbreon
Meg: Eevee
I considered making Mme. Giry an Absol, but Umbreon fits her look better, and that way Meg can be an Eevee.
Serperior is apparently based on French nobility. I had no idea when I chose it for this.
This turned out surprisingly well for me having never drawn half these Pokemon before....
