Mr. O is the head of an Odd Squad headquarters in the Arctic.
Mr. O is portrayed as a dim bulb at times, but confident in leading his agents, providing tools to help them succeed. He wears a pair of lavender-colored glasses, which he often loses track of despite them remaining on his face. Since the weather in which his Headquarters is situated in is always cold, as a result, he is often cold despite his winter attire and longs for warmth.
Brunette hair, dark brown eyes, light olive skin. He also wears glasses.
