However, Rex and Cody were unaware that Rishi Station had secretly been invaded by the Confederacy and taken over by commando droids. When the Obex exited hyperspace over the Rishi moon, Cody contacted Rishi Station via the the Obex's comm unit and was greeted by a commandodroid disguised in clone trooper armor. The droid attempted to forestall the inspection, but Rex and Cody, curious about the supposed clone's response and odd behavior, continued their approach to the listening post. Rex landed the Obex on the post's landing pad atop a large mesa and, after the two clones left the shuttle, they again encountered a commando droid dressed in clone trooper armor. Meanwhile, three rookie clone troopers at the bottom of the mesa, who had been stationed at the listening post and escaped the Separatist attack, saw the Obex land by the station. They realized that the Republic vessel was heading into a trap and launched a flare to warn anyone aboard the Obex.[2]

Back at the station, the disguised droid again tried to convince the officers to leave. However, upon sight of the warning flare in the night sky, Rex was convinced that something was amiss and blasted the droid in the head, a shot that removed its helmet and revealed the deception. Seeing that their ruse was discovered, the other commando droids, having taken defensive positions around the landing pad, began to fire at the clones. Rex and Cody were pinned down by blaster fire, which forced them to take cover behind nearby crates. In the meantime, the commando droids threw several thermal detonators under the shuttle, which destroyed the Obex upon detonation and temporarily stranded the officers on the moon.[2]
Rex and Cody nonetheless used the destruction of the Obex as cover and were able to escape the ambush by grappling down from the landing pad.[6] Meeting up with the stations' surviving clone troopers, the two clone officers were able to soon retake Rishi Station and eventually thwart the Confederacy's planned subsequent invasion of Kamino.[2]
The Obex was crewed by clone officers Rex and Cody during their inspection tour[1] around 21 BBY.[4] During the flight to the Rishi Moon, Rex piloted the shuttle while Cody handled the communications station, contacting Generals Skywalker and Kenobi, as well as Rishi Station.[2]
The shuttle also appears in the non-canonicalvideo gameLEGO Star Wars III: The Clone Wars, which was released on March 22, 2011. The Obex is featured in the game's "General Grievous Chapter 5 - Rookies" level, playing a similar role to that in the "Rookies" episode. In the level, a LEGO version of the Obex lands at Rishi Station, with Rex and Cody jumping out. However, the clone officers soon confront the Separatist commando droids, and a battle ensues, during which three commando droids appear and throw thermal detonators under the Obex, destroying it.
Although the shuttle pictured in Mouse Hunt has not been directly identified as the Obex, The Clone Wars: The Visual Guide confirms that Rex and Cody used the Obex during their inspection tour, including the flight from Pastil to Rishi. "Rookies" also states that the clone officers went directly to Rishi after their inspection of the Pastil tracking station. Due to this evidence, this article concludes that the shuttle seen in Mouse Hunt is indeed the Obex.
