Ratchjack

Ratchjack is the slash ship between Ratchet and Wheeljack from the Transformers fandom.

Season 2
TRIANGULATION

Optimus gives orders to the Autobots to split up to find the artifacts, he tells Ratchet that he should have back up on the mission. Ratchet points out that everyone else already has their assignments, but Optimus was considering the last autobot on Earth. Ratchet can't believe that Optimus is suggesting Wheeljack, who is insubordinate and Bulkhead's partner anyways. Optimus believe that Ratchet would be wise to accept Wheeljack's combat expertise, much to Ratchet's frustration.

TRIAGE

Wheeljack is waiting on his ship when Ratchet arrives through a portal. Wheeljack asks if Optimus thought Ratchet needed back up, but Ratchet says that he thought Wheeljack needed supervision. Wheeljack promises the doc to be on his best behavior, and Ratchet then tells him not to call him doc. Wheeljack agrees to that, but calls Ratchet "sunshine" much to his frustration.

They get into Wheeljack's ship, and Wheeljack asks about everyone being busy with the iocon relics. Ratchet explains the relics, and Wheeljack says that he has Ratchet's back. Ratchet says that he doesn't need anyone for back up, and he that he already proved himself in the war for Cybertron. Wheeljack sarcastically says that he's lucky Ratchet is there, when he gets an alert that a bogey is following them.

Wheeljack tells Ratchet that he might want to grab onto something and starts to move around Soundwave. Ratchet asks if he's trying to get them killed, when Soundwave deploys something. Wheeljack asks what it is and Ratchet says it's a surveillance drone as it starts to fire on them. Ratchet tells Wheeljack to stay on Soundwave, since he's only using the drone to distract them, and Wheeljack says he welcomes a good distraction as he pursuits him. Wheeljack gets behind the drone, but Ratchet says that this is no time to be houndoging as he fires on it. The drone then causes them to nearly crash right into a cliff wall, but Wheeljack is able to maneuver them out of the way, and take down the drone. Ratchet is amazed that he did it, but the drone gets off one last shot and the ship crashes.
