Powers and Abilities
As Sarek is a Vulcan, he presumably possesses the same powers and abilities as are typical of his race. Average Vulcans are generally presented as being three times as strong as a normal human. This is mainly due to planet Vulcan's higher gravity,which not only contributes to inhanced stregnth, but also speed.
In addition, Vulcans are able to go without water for long periods of time, more than a few days easily, due to being accustomed to Vulcan's desert climate. Sarek is also able to stay awake for up to two weeks time before needing to sleep. Another ability Sarek has is telepathy, though only through contact with whomever he is trying to communicate with.
