Jan, Jace and Blip are one of the supporting protagonists in Batman: The Brave and the Bold.
Jan is voiced by James Arnold Taylor, Jace is voiced by Cathy Cavadini and Blip's vocals are provided by Frank Welker.
Jan and Jace are Space Ghost's teenage wards. They are fraternal twins but technically, Jace is two minutes older. They are equipped with jetpacks, a communicator, and inviso power. When they aren't busy arguing, it seems the duo finds trouble. While on a picnic on the planet Zeltor, they came upon the Creature King. Jace alerted Space Ghost to the development. Space Ghost and Batman soon arrived and saved them from certain death.
Blip is the resident pet of Space Ghost's team and worthy partner in the war on intergalactic crime. He is dressed in the same outfit as Jan and Jace, down to the mask. Blip also has a rocket pack and can access inviso power.
