Storm: The Deep World (1978)

From a satellite in orbit around the planet Jupiter, a manned-mission to closely observe the Great Red Spot is about to be launched. The UN emissaries bid the astronaut Storm (that's the only name we're given) good luck before he enters his ship: the aptly named "Storm Probe."
Storm's ship gets a bit to close to the Spot and is drawn in by its hurricane winds. Storm blacks out from the G forces. Mission control is unable to save him. In fact, his ship seems to disappear into the Spot. Storm is lost.

Storm climbs down into the valley. He finds the air is better there, but he gets an unfriendly welcome from sword-wielding warriors. He manages to kill one of them, but ultimately the other knock him out and steal his spacesuit.
The warriors take the loot to their king, Ghast. Ghast realizes the clothes are dwarfed in value by the strange man who wore them. The man who could tell him what these things mean and how they work. He orders him minions to go back out and get him! They do so, taking an iguana--one of the city's giant guardians:
