Vulcan Powers like Spock -
Spock’s Vulcan heritage lends him a variety of abilities. First of all, his strength is about three times that of an average Human’s. His senses are also quite acute, particularly his hearing.
Furthermore, he’s able to manipulate the energy through his fingers, which, when combined with pressing down on certain pressure points, gives him the ability to knock an enemy unconscious (aka the Vulcan Neck Pinch).
He’s also a touch telepath, which gives him not only vaguely empathic abilities that lets him pick up on other people’s emotions, but also the ability to merge minds with other beings. (He’s able to do this without touching anyone if the situation calls for it, but not on so deep of a level.) This is considered a highly intimate act among Vulcans, as it is a practice Vulcans who are close sometimes privately partake in together. However, it can be used to repair neurological damage, erase and restore memories, obtain information, making “suggestions” for other beings to do something (kind of like a Jedi mind-trick, if you're familiar with Star Wars), house and channel another person’s consciousness in his own body, and to communicate thoughts and feelings with another being. Incidentally, he’s able to somewhat use this technique on himself in order to induce a state of hypnosis (in TOS, he uses it to make himself pass out as if he’s ill).
Lastly, he can go into a trance in order to heal himself from fatal injuries. He may need someone to help slap him to his senses when he’s done, though.
And the most incredible power or all, control of his emotions. Very useful, especially when your wife is serving you divorce papers. :frusty:
