Tarzan vs. Conan vs. Indiana Jones vs. Crocodile Dundee

No weapons for Conan or Tarzan. Indiana Jones and Crocodile Dundee have their typical weaponry.

Tarzan and Conan get zero prep.

Indiana Jones gets 2 weeks of prep and full knowledge of Tarzan and Conan (no knowledge of Crocodile Dundee).

Dundee gets 4 weeks of prep and full knowledge of Conan and Tarzan, but none of Indiana Jones.

Meeting: South American jungle; the participants start 500 feet from each another.

So Indy just shoots everyone?

Oh, right. No pistol for Indy.

Indiana wins

pretty much based off the stipulations

If it's book versions for those who have books it's Conan vs Tarzan the others are not in their league. If it's movie versions only maybe crocodile Dundee has a chance as he has some prep feets. Indiana Jones doesn't have any prep feets and he can't match Conan or Tarzan physically even with his whip.

Dundee.

He's got that big 'knoife'.

This comes down to Indy vs Conan. Indy could keep him at bay with his whip, but if Conan gets his hands on him, it may be all over.
