I have a theory about Sylar and his cockroach partner.Well, not really a theory about their friendly relationship and their constant appearance together, but a theory on Sylars constant living state once killed. :)

I have been thinking and Sylar seems to be invincible whenever he is killed. He was killed early in the series when Parkman shot him twice to the ground.But he got up and disappeared.

He was killed when he and Peter fell off the building.But he ran away.Again.

He then got killed by Hiro and his not-as-impressive sword through the heart.But no, he slides under a drain.Wonderful.

Now this may be the worst theory ever, but Sylars similarities to a cockroach pop up now and again, most of the time when he is killed.

Sylar can take the powers of others. Maybe when he was a trainee in the department of brain eating(or whatever he does), he came across the little cockroach. Now Sylar, who can see living things powers and seek them to be his own, probably saw that the cockcroach was basically invincible, it can survive whether its trodden on by a common tramp or survive the world's biggest nuclear bomb.He probably wanted this power for his own, and did his bit of brain surgery on the cockroach for himself.

This explains that whenever Sylar is killed, he can survive nonetheless.

As i said, it doesn't give an excuse for the pathetic bond between the cockroach and Sylar, but maybe this cockroach was the brother of the cockroach that Sylar experimented on. :)

This suggests that the only way Sylar can be killed is for his brain to die.Doing this, he loses all of his powers and the strength to survive.

Tell me your thoughts on this outburst of the connection, and if you hate it, kindly tell me why i am wrong.

If not, praise me. lol
