Body/Sex Count (Based on canon/game info upon request)

Ozai - while he's killed no one directly, he's Fire Lord which places him as the leader of their military so take that as you will / his only confirmed sexual partner was his wife, Ursa

Also, were he not stopped, the number of deaths directly at his hands would have skyrocketed.

Rock - zero/zero

Ash - no exact number but it's suggested that many of the Blanctorche group died when he set their estate on fire / no known sexual partners though

Luke Cage - he's never directly killed anyone though several criminals have died (through other circumstances) while fighting with him / AT LEAST 6 sexual partners though there's probably more

Skaar - He literally called Galactus to his planet so his death count is astronomical / no known sexual partners though
