The names don't help much. Looks like they are "Citron" and "Zakuro"(Pomegranate). :P
citron and pomegranate? maybe we could see gym leaders all based around fruit names? idk.
All the Gym Leaders have names that make puns on their type and a flowering plant.
Also, I think that rockclimber might be female. It appears to have a feminine wasit:hip ratio and what could be small breasts.
Oh. I didn't even think to consider that. It's been quite a long time since I actually saw new Pokemon characters I guess. I only looked at the head and accessories. Zakuro does seem to have a feminine shape. I guess Miss Pomegranate might be our first female Rock Gym Leader?
