Johnny (Sweet tooth)

He's very kind, he likes to help. The world they live in is plagued by a disease and hybrids; one hybrid, Gus, started it all. Johnny is Abbot's brother. Abbot is searching for a cure, and Johnny is obligated to help his brother, as it's all he has left, even if it means doing things he doesn't want to... He's a good person, however, his brother isn't. Abbot killed Peter, the crocodile hybrid, and Roir, the chameleon hybrid. There's a group that HELPS the hybrids called the "Animal Army," and another that destroys them, calling them the "Last Men." The virus disease ONLY AFFECTS HUMANS! Everything was caused by Pajarita, who created the first hybrid, Gus. One experiment brought the hybrids, and another the virus. Abbot believes the hybrids are to blame for the disease. Abbot uses the hybrids to create the cure.

army led by Abbot who are in charge of killing the half-human half-animal hybrids.

Unlike the last men, the animal army saves the hybrids.
