Isaac was in fights because he was picked on for reading instead of following the usual professions of making wine, haunting houses, and not making horror music (Which are professions most Jersey Bats take on since other species take on the other professions). After a fight he just decided to pack what he could and head off to a better town, where people could be a bit more accepting. Finally he into a town stopped at a restaurant where he met Mr. Pentale. Isaac was confused on what Pentale was doing far from his kind's homeland. To which Mr.Pentale happily explained. After a few talks, Isaac decided to stay with Mr.Pentale to get back up on his feet in hopes of having a better life. By reading Pentales' work to see about second thoughts, as well as writing his own horror works. Which Pentale in turn helps him with as well.

Granted after meeting Mr. Pentale, he did get better with his attitude and personal issues. But he will still fight you if you keep harassing him or his friends.

About time I uploaded his ref sheet. I needed to get my thoughts together for his story and tweak his shading color so you can keep your eyes and figure out which colors are which.
