[About the Neo, well, is there even a silver of a chance that that alligator is going to help us?]
Laughable!
The Neo lives to kill. The Neo might be able to destroy the Sun God by itself, but I don't see the Neo lifting a claw for this situation. We would need to almost kill it to get it to listen to us. Only one first gen has done that.
The first gen of flesh and blood. They did it by mistake when the Neo went up to them in its weakest form to spy upon some death. The first gen of flesh and blood, who at the time wasn't even a god! They snapped up the Neo and nearly killed it, but the Neo made a deal. The Neo gave them great power, the powers of the gods in turn for freedom. The deal was taken, and the Neo was freed.
The issue with killing the Neo is the fact that many stories point to needing to want the whole universe dead to kill the Neo. Every single atom, every single fiber, you must want it dead, for the Neo is the universe. It's said if you even want one thing in the universe to live you will hold back, and that's when the Neo will kill you.
Though I have heard an almost never told story about the Neo. That if one, truely loves, or at least believes in the betterment of everything in the universe, they will be able to kill the Neo and make the perfect universe. Of course, as anyone who knows the origin story of the limbo gods knows, the perfect universe is likely the worst idea ever. There should always be some conflict in the universe, a perfect universe cannot be one without conflict. It is impossible. If you don't know about the origin story, how about I tell you on our way to see the Helper? It seems like it'll be highly relevant at that time.
