a sci fi film sometime in the 80s or 90s with a monster with a horn

[biosinger]

there is a monster they have to kill by ripping it's horn out of its head. there was also an evil emperor dude the monster guarded. i also think there was a dagger or some magical weapon. it's live action. the monster wasn't cgi. it was a prop. i remember the monster was dark red with hard, wrinkly skin. a horn similar to a rhino's protruded from its forehead. i remember someone jumping on it from behind and ripping the horn out of its head. it was like a slightly-bigger-than-human-sized rancor... with a horn. it was a medieval-type setting. the death scene of this monster takes place in the throne room of the evil emperor dude.

Probably Conan the Destroyer.

Here's the monster.
