Unfortunately, our game currently only accepts the kinds of characters listed above. Nira Tyr would be appable in her PTU version as an original fandom character or her "real world" version as an OC. The other characters couldn't be apped as non-canon AUs. They could only be applied for from their canons.

We try to let characters with water-related powers keep them where possible. From our understanding of Mako in canon, it's an expert sailor's intuition about the ocean which is fine!

Characters are generally not transformed on arrival. Transformations like you described would have to be pursued through genetic research in the labs.
