>>58106473At least during his tenure as Champion, Garchomp would be a solid team member both because he sees it as a strong pokemon on a strong trainer's team, but also because it isnt weighed down by rain, unlike incineroar. The angry, violent Hydreigon could also fit in, acting similarly, but not as unpredictably, as Porygon-Z.
I just like dragons, and though I can't see him running a full team of them, they're definitely the type that exudes Power and Strength, and I can definitely see him trying a few of them out before he realizes he isn't yet built for their shit.
