He was assassinated by a wrestler

Commodus uncontrollably lost his mind as he proclaimed himself the new Romulus. He even intended to assassinate every senator while ruling the Empire from the gladiator barracks. Marcia attempted to halt Commodus once she became aware of it. Although Commodus viewed Marcia as his wife and heeded his counsel, he disregarded her advice this time. He attempted to assassinate her instead when she rejected his plan to govern the Roman Empire with unlimited power. Marcia managed to survive in some way thanks to one of Commodus' sex slaves. The plot to overthrow Commodus had already begun. Marcia also joined the faction calling for Commodus' demise.

On December 31, 192, the revolting gang tainted Commodus' food, but he threw the poison back up. A wrestler by the name of Narcissus went to kill Commodus after the initial attempt. Narcissus strangled Commodus when he was cleaning up the vomit in the bathtub. The harsh emperor's demise came about in this manner. One of the characteristics was that bad Roman emperors passed away earlier than usual. Both Commodus and Caracalla passed away at the age of 31, which they both did. Additionally, their manner of death was identical; they were both slain using methods they liked. One of Caracalla's troops killed the emperor. Likewise, one of the gladiators killed Commodus.
