Weezer is the monster tamer and trainer for the Zombozo circus. He utilizes his innate kenku ability to mimic any sound to train the monsters more effectively.
Like many kenku, he loves shiny things, especially his glittery hat of disguise. He dislikes the pixie gang because they tend to prank him by stealing his shinies.
The show features several monsters that Weezer has trained, including bulettes Fair & Foul, manticore Sting, otyugh Glump, and owlbears Fuzzy & Wuzzy.
