Jimmy is the pilot of Tortuga HQ. Jimmy Z is not as knowledgeable about animals as the rest of the Wild Kratts crew. He is shown to be nervous. He cannot live without his game controller, which he uses to teleport items and Creature Power Disks to the Kratts when they are on their adventures. He sometimes helps Aviva with inventions by handing her the items she needs as she works, and usually has hilarious results when he helps her test the prototype, as in the time when they were testing bioluminesce and his hair turned green in the episode "Fireflies". He does not have a creature power suit, but his creaturepod color is orange. He gets afraid easily.
