Gammadoodler
Hero
I dunno, I feel like when he went to the exotic locations, he encountered exotic creatures.You said yourself: Indiana Jones rarely if ever encountered monsters, and he went to all sorts of exotic locations.
Whatever the you'd say was in the ark of the covenant, the ghost knight, some aliens at one point.
He didn't fight them (that I recall), but there was usually something weird to find in the weird places.
And those movies are set in near-modern Earth rather than a fantasy world.
