Caustic: Male Human 5'7 127lb He is gas boi. I have another character like him named Azieza. So basically he was experimented on in the Tanchietay labs with a different type of deadly gas. He just goes by Caustic because he figured it was a cool name and he can't remember his real name. He's hardheaded and shy but does really like people and is very helpful if he really cares about you. He may look spooky but it's just his style preferences. Also, he's a big foodie.
