Ayala

Ayala was a male Human who was a Maquis who served as Chakotay's right-hand man aboard the raider Val Jean. When he became stranded in the Delta Quadrant aboard the Starfleet vessel USS Voyager, he joined its crew as a security officer. He returned to the Alpha Quadrant with Voyager in 2377.

Stranded in the Delta Quadrant
In 2371, Ayala was one of Chakotay's crew aboard the Val Jean. When Gul Evek's ship, the Vetar, attacked the Maquis vessel in the Badlands, he attempted to make repairs to the bridge. After the Val Jean was transported to the Delta Quadrant by the Caretaker's array, Ayala was brought aboard the array for testing by the Caretaker. He was returned to the Val Jean unharmed. He later boarded Voyager along with Chakotay and Tuvok at Captain Kathryn Janeway's invitation. When it was revealed that Tuvok was a spy for the Federation, Ayala attempted to attack him, but was held back by Chakotay. He was issued a compression phaser rifle and beamed to the array with an away team to scout for Harry Kim and B'Elanna Torres with Tuvok, but was soon returned to Voyager by the Caretaker. The Val Jean was later destroyed after it rammed a Kazon carrier vessel, and the Maquis were forced to join Voyager's crew for the journey home.

Ayala was transported aboard Voyager with B'Elanna Torres and at least two other Maquis crew. In an alternate timeline created several years later by a spatial rift, he was trapped in the transporter room with the Maquis. Chakotay, who originated from the time period where Voyager encountered the rift, injected Torres and Ayala with a chroniton-infused serum which allowed them to move between the time periods, to retake main engineering from Seska. This alternate timeline was later erased when a chroniton field brought Voyager back into temporal sync.
