Brian wears a fur coat and has several dead animals covering his coat to add to his hunter nature. He even uses a dead cat as his hat. He has a fuzzy beard and is always shifting his eyes from left to right.
As he was locked up in a facility for so long, Brian ended up escaping and began to chase Gabe around as an animal. He often insults Gabe and states that he will shit on him.
He almost killed Gabe and Tycho Brahe with a javelin, but it missed. He then tried again with a bear trap, but that failed also.
Brian gave up after a while, seemingly unable to kill Gabe.
