Jovian Jujitsu was a martial art used by the Inspector.

The Third Inspector liked to mention his prowess Jovian Jujitsu to threaten his enemies but was rarely seen to use it against them.

Conversely, the Fourth Inspector used it quite often during his exile on Earth with Exo-Pol, such as when fighting the Rostraans or the Circuit-Chaps. After his official reintegration into Infinity Knight society, he tended to use his Optic Pocketknife or simply shoot at the monsters, not bothering anymore with the Jujitsu.
