The next show in the series—The Brave Fighter of Sun Fighbird—used a similar concept, focusing more on self-parodying humor by having the robot leader take possession of a humanoid-simulating android instead (which interfaces with the Fire Jet to form the robot Fighbird). This forces him to coexist with humanity on their terms, causing a great deal of trouble. The concept of the "Space Police Force" otherwise remains intact (though not connected to the earlier series), a key difference being that the mecha that Fighbird and one of the combiner teams use was developed previously by a human scientist, Hiroshi Amano, whose grandson Kenta accompanies the Space Police in their battles.
