Ty is portrayed by Kai Wener.
Ty was born sometime around the early 2410s to Doctor Claire Finn, an experienced medical officer in the Planetary Union. Ty has no father. Claire desired children, but by her own description, she never found a man suited to be her husband. Ty's older brother Marcus was born through artificial impregnation of his mother. Several years later, his brother Ty was born by the same method.
Aboard the Orville Edit
Claire requested a transfer to the Orville in the year 2419, and Marcus and Ty followed her, living on the ship as civilian passengers. Ty attends school on board the ship. In his free time, he enjoys playing Space Dragons in the Environmental Simulator.
Shuttle crash Edit
In the winter of 2420, Claire wants to spend more time with her sons, so she plans a vacation to Arboreus Prime. Ty is particularly excited about riding sky cranes and gravity bubbles, waking his mother early on the day of the trip. The trio leaves in a shuttle piloted by Science Officer Isaac.
Claire demands that Marcus not play games on an unidentified, hand-held device for the duration of their trip to Arboreus. However, Ty is annoyed that Marcus disobeys. When Marcus drops the device during mid-flight turbulence due to a gravity shear, Ty recovers and throws it, hitting the shuttle's navigational console. The shuttle is thrown off-course, sucked into the gravity well of a nearby spatial anomaly.
The shuttle emerges from the fold badly damaged and in uncharted space. To survive, Isaac intentionally crashes them onto the surface of the nearest inhabitable moon, but the shuttle splits in two and Claire is separated from the others.
Isaac decides to leave the boys in search of Claire. The decision would risk their lives. That night, a cannibalistic inhabitant of the moon preys on the children from the dark of the forest. The man grabs Ty and attempts to abscond, and Marcus is either too afraid or too unfamiliar with the PM-44 energy weapon to shoot him. Fortunately, from elsewhere in the woods, Isaac momentarily stuns the man with his own PM-44. The kidnapper flees without Ty.
Isaac could not find Claire on foot, but he believes that re-powering the shuttle with dysonium would allow them to conduct a wider search and to send a distress message to the Orville. A brief search with Isaac's comscanner reveals possible surface veins of the energy source several kilometers away. The three set off for the source of dysonium. They are waylayed by a group of starving cannibals who demand the children, but Isaac is able to fend them off. The trio finds enough dysonium to restore power to the shuttle, and they begin their return.
Meanwhile, the Orville began a search for them. The crew finds the correct gas giant, but with 36 habitable moons, they must search one at a time. That night, Ty grows upset because his mother is missing and afraid of the inhabitants preying on them. At the boys' request, Isaac comforts him with a bedtime story read in Claire's voice.
The next morning, Ty shows symptoms of a serious illness. Unbeknownst to them, the child is sick with poloxus poisoning from exposure to contaminated water. Claire messages Isaac from her comscanner and receives their coordinates. She was taken by an inhabitant named Drogen shortly after the crash and held captive; she kills Drogen and leaves. Along the way, she is followed by a throng of cannibals.
When Claire reaches the three at the shuttle, Isaac sends a brief distress signal to the Orville. Claire realizes that a cure for poloxus is possible, but that she needs access to her medical laboratory. The cannibals attack the four. Isaac, Claire, and Marcus defend themselves until the Orville arrives. Ty is taken to Sick Bay, where his mother synthesizes a cure for his illness and he makes a full recovery.
- In February, 2420, Marcus and Ty are locked out of their quarters when Claire copulates with Lieutenant Yaphit. They complain to Chief of Security Alara Kitan.
- Around April, Marcus and Ty offer to help Isaac scan the Orville after a spatial anomaly damages part of the ship. Isaac initially rejects their help but, after Navigator John LaMarr criticizes him, relents.
