I remember vikings or something like a viking vs these people or creatures from underground and they fight them or have a competition about them. I remember it from the late 80 maybe early 90's any help be appreciated!

Hi, could this be the SNES game 'The Lost Vikings'?

It was a cartoon. It wasn't a video game. It was like a cartoon of sorts where some vikings or gladiators vs these aliens or people from under the ground.
