Neo-Megas are the super-smart creations of the Neo-Sapiens, (although a human scientist made the first one), and near the end, almost all of the Neo-Megas were to be killed by the Neo-Sapiens, and most were.

    Neo-Animals are the creations of the Neo-Megas, two batches were made, ("I am second brood, more smart"), there were cats, lizards, crabs and a bunch of other ones, they are all very strong and extremely hard to kill, not even Able-Squad was able to kill them, (for those who don't know, Able-Squad is the best squadron in the Exo-Fleet).

    Neo-Lords are the combination of the other Neo-Animals, stronger, smarter, faster, and can fly, one even brought down J.T. Marsh, (the leader of Able-Squad),
they are much harder to kill then the Neo-Animals, so that's about it. Bye!
