Tycho Celchu, The need for new pilots to fill the ranks of Rebel squadrons after Yavin was acute. Many pilots volunteered, but only the very good ones joined Wedge in what would become Rogue Squadron. Lt. Tycho Celchu was one of the best. On his 21st birthday, Tycho, an Imperial pilot, had been speaking to his family back on Alderaan via the Imperial Holonet, when the transmission went down, a common occurrence during the Galactic Civil War. Tycho later learned that the Death Star had just destroyed his homeworld, family, and life. Tycho deserted active service and disappeared into the hidden channels that the Rebel Alliance ran. Already a formidable TIE fighter pilot through this training with then-Captain Soontir Fel Celchu quickly found his way into the ranks of the Rebel Fleet, being recruited by Luke Skywalker for his unit. During the Battle of Endor, as Commander Wedge Antilles and the Millennium Falcon attempted to destroy the second Death Star's core, Tycho flew an A-wing into the space station's unfinished superstructure, luring TIEs away from the critical operation. Tycho would have preferred flying an X-wing, but he had been trained on an A-wing, and filled in as needed for the operation's success. When Wedge Antilles became leader of the squadron, Tycho became Antilles' second, a position he has held ever since. Tycho carried a love for adventure long before the destruction of Alderaan sent him over to side with the Rebellion. Now, he feels that it is much better channeled into the cause of freedom. An outstanding pilot and fearless ground operative. Tycho uses his accumulated knowledge of Imperial strategies, codes, and policies against his former masters. For example, Tycho would never have attempted to impersonate a transferring pilot on Cilpar, had he not known that a rural garrison would not necessarily have the comprehensive identification techniques so prevalent in the paranoid, central Empire. Tycho has developed an ongoing relationship with the enigmatic Winter; although they have spent more time together dodging blaster bolts than they have counting stars in each other's eyes. Even in the most desperate of situations, though, the pair has found ways to enjoy each other's company. After volunteering for a daring covert mission to then-Imperial held Coruscant, more commonly known as Imperial Center, in a TIE fighter, Tycho was captured and sent to Lusankya, Ysanne Isard's dreaded prison fortress, where minds are altered to her will.

After his escape, Tycho was never quite trusted by New Republic intelligence again, but was returned to Rogue Squadron because of Wedge's close ties to him. Tycho was given only an unarmed Imperial shuttle to fly, and was given the position of executive officer. After the events of the Krytos Trap and the court case proving his innocence, Tycho was accepted again as one of the Rogues, and was released of all charges. He became Rogue Leader when Wedge Antilles left the Squadron to create Wraith Squadron. He later retired from the squadron and settled down.
