Magic Brian

Magic Brian is a wizard who severely wounds Taako in a magical wizard duel in Wave Echo Cave. After Taako is revived, he strikes Magic Brian with a magic missle, wounding him severely. Magic Brian then attempts to disguise himself as Gundren Rockseeker, but Magnus Burnsides sees through this illusion and kills Magic Brian by kicking him into a pit. He then proceeds to fall for at least a full minute, expressing how proud he is that the adventurers have solved his magical riddle. He owned a giant spider, also named Bryan, but with a 'Y'.

Somehow, Magic Brian wasn't inhibited by the Void Fish's memory removal effect, as evidenced by him asking Taako, Magnus, and Merle whether they were part of the Bureau of Balance
