* The Rebellion and their allies, the Supers, are traveling through time in a risky attempt to eradicate Sylar completely from history. With the help of a Super, they bounce from one point in time to another. Each time period contains a different Sylar and a different set of problems.
20 years into the future ;; Sylar is president under the guise of the deceased Nathan Petrelli. He controls a group known as the 'Supers', some of the most powerful people on the planet thanks to their background as government test subjects. Attacking Sylar is as good as committing suicide.
2 years into the future :: season 4 ;; Nathan Petrelli is dead but Sylar has been forced to take his place. At least, his body has. His mind is somewhere else entirely. No one will tell where. Split apart and confused, he is weak. Taking him down should be easy.
present time :: season 2 ;; New York has been saved from an untimely end thanks to a few brave souls and no thanks to some cowardly ones. Sylar was left for dead but someone has plans for him. Powerless and recovering, he ought to be a cinch to kill.
past :: pre-season 1 ;; Who was the man before he became the monster? Sylar is infamous. Gabriel Gray is nobody. And an incredibly hard man to find. The Rebellion don't know his name but they know his face. Defenseless and oblivious, Gabriel will be no trouble.
past :: early 1980's ;; The Company is young and so is Angela Petrelli. Sort of. The future is a long way off and there's plenty of time. Right? Gabriel is just a kid. And kids are easy to murder. That's what this is. But it's for the good of the future.
