...it's time to look at a few of the time travels of Superman, Captain Kirk of the starship Enterprise on Star Trek and the Doctor of Doctor Who in the comics!
It's quite the wild ride, as characters met themselves over the years, crossing over generations...
...and it might even be as interesting as the cover mock-up of Super-Team Family provided!
Boy meets Man of Steel
Superboy accidently landed in the future, met Lois Lane and his future self (because, these early adventures of Superboy weren't those of a clone, they were of Superman, when he was a boy). The two were stuck in one time, and had to put their heads together (sorry for the pun) to figure out how to separate themselves.
There were even Superman meetings over in Smallville, where Tom Welling (as Clark Kent) met previous actors who played Superman (Christopher Reeve as Dr. Virgil Swann, and Dean Cain as Dr. Curtis Knox), so the Supermen didn't quite meet each other as Superman (at least in the "real world"), but close....
...oh, so close.
Star Trek Generations meet
This story had the crew of the Enterprise-A (between Star Trek III: The Search For Spock and Star Trek IV: the Voyage Home) meet with the TV series crew from Star Trek's first season (including Yeoman Rand and Nurse Chapel, and not Pavel Chekov, who wasn't added to the crew until the TV shows second season). It also showed the value in getting the complete Star Trek franchise (as the 18 issues of the original Marvel Star Trek run only had rights to likenesses and concepts of Star Trek: The Motion Picture).
...and even the most recent two Star Trek movies that rebooted Kirk, Spock and the rest of his loyal crew!).
Later comics had the various crews meet, and they even branched out and met other licensed characters...like one of the most frequent time travelers of them all!
Over the course of these twelve issues, the Doctor's companions were disappearing (as seen starting with the first Doctor in issue #1, the second Doctor in issue #2, and so on), until all 11 Doctors gathered to solve the problem and find which companion was behind this in the 12th issue, as each Doctor appeared once a month all over 2013, all written by Scott and David Tipton and a variety of artists!
A chance to see all the Doctors in action once again (from the 1st - William Hartnell, 2nd - Patrick Troughton, 3rd - Jon Pertwee, 10th - David Tennant, 11th - Matt Smith, 4th - Tom Baker, 9th - Christopher Eccleston, 5th - Peter Davison, 8th - Paul McGann, 7th - Sylvester McCoy and 6th - Colin Baker), all in one story, helping to celebrate Doctor Who's 50th Anniversary in a story the Silence couldn't even make you forget!
Still, here we are with the newest Doctor (Peter Capaldi), and I bet he's feeling left out after his renewal...
