That super lycan, the one from underworld awakening, he was badass. I was rooting for him. The movie was okay except for the fact that the werewolves weren't the good guys.
So, here's a suggestion you might like. How about mixing together plots 1 and 3. Lycans were created through gene splicing for war purposes... War happened... SHTF... Now we're all in post apocalyptic hell. Lycan's being what they are, have an inherent advantage in this new messed up world? And maybe a disadvantage also? Because normal humans don't like them, for whatever reasons, so lycan's don't go about showing off their monstrous forms for no good reason. Something around those lines.
