When Pericles lost contact while piloting the space pod, Leo snuck onboard another pod and followed him, only to get caught in the same electrical storm. However his commander, Vasich, believed in sending a chimp before sending a man to explore something dangerous. Leo didn't like the idea and would have preferred to go himself. When a great electromagnetic storm was detected in space, Pericles was dispatched in a small craft to check it out. He worked regularly with a chimp named Pericles who he trained to perform basic tasks out in space. Leo Davidson was an astronaut officer who was stationed onboard the space station Oberon in 2029 researching genetic engineering on chimps, orangutans and gorillas. Captain Leo Davidson is the main protagonist of the 2001 Planet of the Apes movie.
