From Heroes Wiki
Marty Ceppo is a version of Marty in The World Entire universe. He is a human and Nathan's Chief of Staff.
Marty interrupts Nathan and his wife at the pool, showing him a simulation of the effects of the worldwide Special-caused natural disasters, which would result in an event much like the prophesied Broken Earth Cataclysm. He is present at all of President Petrelli's subsequent press conferences.
