Friendbringers has assimilated Spirit Animal into itself and copied or absorbed a powerset-generating ability of yours, evolving greatly in the process: In exchange for the minor drawback of requiring all of your Friends to take on animal or animal-like forms, you now have a total of six Friends, and each of them may be any size that Spirit Animal could manifest.
Furthermore, your Friends now all have a secondary power that allows them to alter and boost your powerset: By either riding, carrying or otherwise directly interecting in a similar way with a Friend, they can change your other powers in a manner thematically appropriate with whatever animal they resemble, almost always in a way that directly upgrades it - an avian Friend might alter your Blaster, Striker or Shaker abilities to include razor feathers, or alter your Mover abilities to include gliding or outright flight, for example.
