Brian Tae is one of Austin followers, or basically friends. His main monster is Sharth, but however he has encountered a few rare monsters on his journey.
Based on what Austin's page said, Brian Tae demonstrated how to catch a monster by catching a Coyaos. Brian Tae basically makes his way as a tamer and becoming Austin's friend. His main goal is also like Austin's, where he tries to catch all the monsters he can. Even though he might quiet and calm, he is very fierce in battle. But however, he is sometimes agitated and screams about how annoying the world is. Brian Tae doesn't really seem about how Austin and his friends act, but he is more interested in catching monsters.
