Oz is Octavia's partner. He is invisible, which is nothing unusual at Odd Squad. He became invisible when he misfired a gadget while he and Octavia were battling Jellybean Joe during "Whatever Happened to Agent Oz?".
His favorite food is unknown, as currently it says Owen's quote: "Wish I could, but...", which might imply that invisible agents cannot eat.
Ms. O: Boss
"I'll just use my handcuffinator!"
"Odd Squad is my life."
