RX-24 or "Rex", is an RX-series pilot droid who works for Star Tours, and is a pilot of a StarSpeeder 3000. He appears in both incarnations of the Star Tours attraction and the Disney XD show Star Wars Rebels, and is set to appear as a DJ at a cantina located in Star Wars: Galaxy's Edge, a themed land set to open at Disneyland and Disney's Hollywood Studios in 2019.
Rex appeared as the pilot in the original Star Tours attraction. Much like all droids of the RX series, Rex has a talkative and friendly attitude, and focuses more on his guest interaction than the safety and the schedule of the flight.
He was also in love with ROX-N, a feminine-programmed droid that worked at the L’Astroport Services Interstellaires.
Rex's first flight went wrong right from the beginning, he took a wrong turn at the Launchpad, and, forgetting where the brakes were, proceeded to fly the StarSpeeder 3000 down into the ship yard, but managed to steer it back up and out into space. He then initiated lightspeed with R2-D2 to Endor.
The StarSpeeder accidentally passed Endor and flew into a comet field, navigating through a large one and crashing out of it. He prepared to make turn around back to Endor, but they got caught in a Tractor-Beam of an Imperial Star Destroyer.
A Rebel Alliance ship made contact with the StarSpeeder, helping them break free of the tractor beam and then proceeded to tell Rex to follow them into the Death Star Run. He blew up a couple of Tie Fighters before moving away from the Death Star before it exploded, and the took the jump to hyperspace back to the Star Tours space port. He narrowly avoided colliding with a gasoline truck, before the StarSpeeder docked, and all the passengers exited the craft.
Former RX-24 Audio-Animatronics appear as various RX-series droids in the the queue area of Star Tours: The Adventures Continue in the droid customs scene. The attraction, set several years before the events of the original Star Tours attraction, depicts the RX-series droids as newly-delivered to the Star Tours agency, which has marked them defective. One of these former Audio-Animatronics figures is actually RX-24, malfunctioning and randomly repeating his dialogue from the original attraction (plus one new line of dialogue in which he says he has technical difficulties). In the Tokyo Disneyland version of the attraction, another RX-series droid appears as a hitchhiking droid.
On July 15, 2017, it was announced at the D23 Expo that Rex would appear in the new Star Wars: Galaxy's Edge, a new themed land under construction at Disneyland and Disney's Hollywood Studios, where Rex is set to appear as a DJ in a cantina.
Rex appears in the Star Wars Rebels episode "Droids in Distress", voiced once again by Paul Reubens, who is famous for the portrayal of the character Pee-Wee Herman. RX-24's appearance in Rebels is the first official appearance in Star Wars canon.
He flies the transport ship ST-45 (a reference to the original Star Tours attraction) from Lothal to Garell. When Ezra and Chopper are fighting, Maketh Tua asks for the Astromech droids to remain with her, but Rex corrects her in imperial law by saying all traveling droids (save for himself) must be put in the back, including Maketh's interpreter C-3PO.
- Rex's poor flight skills may be due to a transparent red ribbon hanging from his body reading "REMOVE BEFORE FLIGHT."
- Rex made a cameo in Disney Sing Along Songs: Disneyland Fun.
- His look inspired the design of AC-38, a droid from Star Tours: The Adventures Continue.
- In the queue line of the original attraction, the announcer proclaims that the new RX droids are the newest, safest, and most advanced pilot droids in the galaxy.
- Rex utters Pee Wee Herman's iconic laugh several times during the attraction, and also utters a similar scream.
- Rex went through several personality changes during the attraction's development. At first, he was conceived as a witty tour guide. Later, he was conceived as a brazen veteran-a deranged and broken-down droid left over from the Clone Wars named "Crazy Harry".
- Rex is infamous for having a very ear-grating scream in the Disneyland Paris version of the attraction, and to a lesser extent, the Tokyo version.
