i feel like kabu and brassius would get along well. they both are very passionate about what they do and they are both pretty cool-headed/strategic while still hating to lose (i mean look at both of their losing poses). they both also break the mold of what people think of when they think of trainers/gym leaders of their type (fire-type trainers usually being hot-headed and impulsive and grass-type trainers usually being cheery and peaceful).
