The Stalker has the ability to override most abilities, as well as the means to appear without detection anywhere. If he has these abilities, and he has his hands on a warframe. It is debated whether he was a rogue tenno (likely when the "Order 66" of tenno came about) or in fact a very skilled assassin who managed to steal a warframe, through methods unknown to us. Either way, if he has such powers, it's a safe bet he has had the means to develop something akin to immortality, especially with the time he would have to develop it. Also, although this may be just due to the repetitive nature of the game, he has the ability to survive millions of tenno encounters.
