Disney's the Legend of Tarzan
One giant crimson red python named Hista appears in the episode "The Challenger" and was threatening the gorilla family until Tarzan and Moyo manage to lure him into a tar pit, where the snake dies after sinking into it. His weakness is that he, like other snakes, has poor vision and senses body heat to hunt, a weakness Tarzan uses to his advantage.
