10 Ways William Shatner Can Play Kirk Again In Star Trek 3
9. Q
Being omnipotent, the Q entity can pretty much do whatever he/it wants to do. Time has no meaning so there is no reason he couldn't click his fingers and appear in the new timeline. He also has the power over life and death and therefore could bring the original Kirk back to life, all you would need is a reason why. Q has always shown a keen interest in the direction humanity is developing, and even though it might not seem like it at first, usually Q has the best intentions for humanity at heart. Even when Q put all humanity on trial in Star Trek: The Next Generation, he subtly showed Picard the direction he should be going in. He's not really a Star Trek villain, he's a Q. Maybe the Q continuum is not happy with the way the timeline has been altered and the way it changed Kirk, perhaps the changes will fundamentally effect the future of humanity and Kirk is pivotal to that. The new Kirk is much more reckless than Shatner-Kirk and Q sees that he needs a proverbial kick up the butt to send him on the path he should be on. So he brings in Shatner-Kirk to teach him to be the person he should be.
