I love Indy but Rambo is bred/created killing machine.
Consider also, Indy's backed up by Sean Connery, Rambo's back up is Richard Crenna.
Nah, even with his back up dead, Rambo wins.
Especially after I tell him Connery killed Crenna. This time it's personal.
What if zombie Crenna attacks Rambo from behind while Indy and his dad attack head on?
