Ava is the blonde-popular-cheerleader Pink Ranger who doesn't really want to save the world, but does it anyway because someone has to. Seriously, universe, does she have to do everything herself? B( (She is also most likely the real leader, regardless of the color of her spandex. Pink is just lightish-red, after all.)

Wyn would be a rather misunderstood enemy scientist who ends up doing a heel face turn and helps the Rangers by being their expospeak person advisor.

Since there's no archetype for 'actual pacifist', I think Hunter's stuck being a bystander.
