Beneath the Planet of the Apes
In 2015 IDW Publishing produced a mini series call "Planet of the Apes - The Primate Directive" where the crew of the TOS Enterprise followed a Klingon ship into the universe of "Beneath the Planet of the Apes" which the Klingons are trying to use as a way to get around the Organian Treaty by expanding their empire into another universe. Both crews of the Enterprise and Klingon ship become behind the scenes characters in the events of "Beneath the Planet of the Apes". A tricorder with the sling-shot effect is left behind and is used by Dr. Milo to allow the spaceship he, Cornelius, and Zira are in to travel back through time.
