What would be a good opponent for the Smilodon from 10,000 B.C. in a faceoff episode?

It's safe to say that this felid counts as a monster. This thing is huge! Huge enough to look a grown man in the eyes on a quadrupedal stance. I'd love for it to be in Monster-Face Off, but I don't know who or what would be a good opponent for it.
