10 Best Doctor Who Crossovers Ever
7. A Little Help From My Friends
The 13th Doctor's first crossover didn't come in the form of an episode. Instead, it dropped in a new series from Titan called Doctor Who: The Thirteenth Doctor Season Two. Not only does the 13th Doctor come into contact with her past self, but she does it during one of the 10th's greatest episodes.
During "Blink," the 10th Doctor and Martha Jones were stuck in 1969, thanks to a Weeping Angel, but their adventure wasn't shown in great detail during that episode. As "A Little Help From My Friends" demonstrates, their time in the '60s was quite the adventure.
The 13th Doctor, Yaz, Graham, and Ryan make their way to New York City in '69 to check out Woodstock, but the TARDIS had other ideas. Instead, they wind up in London, where they find the 10th Doctor and Martha. The two teams wind up working together to thwart a Weeping Angel takeover of London, and it's epic!
The first four issues of the comic cover the time travel shenanigans that brought the 13th and 10th Doctors together, and they make for a wonderful continuation of the 13th Doctor's adventures. The books also delve deeper into her companions' personalities — far more than what has been revealed on the show.
