Hmm... well, Jay and his group would be running around, but their purpose in doing so is like Maximum Ride; a bit of a "save our species" sort of thing. Of course, any Morphski they find would be asked to join the group... but perhaps they could be causing a little bit of, say, mischief? Making a name for themselves. And the Morphski that they didn't see might try to join the Rebellion. Hey, you can't force people, right?
Hmm... well, I'd probably use Aepep again, but with a few tweaks. He'd be... well, he wouldn't be on Jay's team, but he'd be an ally. A recruiter, perhaps. That way, the group would be more split up, and people had a better chance of joining the Rebellion (or whatever its called.)
I suppose the Morphski could go kinda like this: The Morphski themselves are able to transform into any animal after interacting with the creature physically. Once having physical contact with an animal, a Morphski can transform into the animal at any given moment. However, this technique requires practice. Every Morphski has one certain animal that they can transform into freely; whether or not they have trouble at it is depending on their skills.
The Morph drains some if not little energy, but it becomes harder to Morph back into human form as time goes by. If too much time goes by, the Morphski becomes temporarily unable to Morph into human form. This can be corrected using the same technique as before; a Morphed Morphski can transform back into human form through the contact of his or her personal belongings. A Morphski can never become stuck in its favoured or Ultimate form (the animal it can Morph into freely).
As for the other species... well, since I don't really know what they are, I'd love to hear a few details.
