Bo Briantus was a chemist of the year 9767 AD. He developed an antidote to the chemicals with which Kroll Mull drugged his subjects to make them think the images from his dream palaces were real. He broke into a dream palace where the Black Terror and Tim were imprisoned and helped them escape. Together, they overthrew Kroll Mull and brought him to justice using atomic weapons Briantus had designed. The Black Terror appointed Bo Briantus as his deputy and returned to the present with a little memento from the future.
