Unfortunately…the Tarantula becomes one of Spidey's deadliest foes!

    Julius Caesar sets twelve tasks that only gods could perform, similar to the twelve tasks of Hercules, to prove that the Gauls are mere mortals. If the Gauls succeed, he will admit defeat and let the Gauls become the rulers of Rome, but if they fail, they will become his slaves. The challenge is accepted and Asterix and Obelix are chosen to represent the village, eventually succeeding in all tasks. At the end Caesar admits the Gauls' superiority. He is shown living in retirement married to Cleopatra, although it is explained that the ending is what it is because it's just a cartoon film, so "anything goes".

    One of the astronauts is killed by a creature, but the other, Woodrow Decker, is transported into a pastoral countryside by the monolith. Here he rapidly ages until he dies and is converted by the monolith into an embryo-type creature referred to as a 'new seed' to explore the galaxy.
