Zola Malfeazium used a Flying Coat to escape Castle Heterodyne while tripped out on Moveit 11. She was later shot down and admitted to the Great Hospital to have her wounds treated. The suit is officially known as the Flight Raiment of King Darius the Incandescent. Zola learned of it from the version of Lucrezia that was downloaded into her brain. It was part of the old Heterodynes' collection of interesting bits and pieces in the library/cabinet.
