In that year, Tyler was one of a number of Enterprise crewmembers injured during a battle on planet Rigel VII. After the incident, Captain Pike ordered the Enterprise to Vega colony in order to replace any crewmembers who required hospitalization. En route, however, the crew detected a distress signal from the SS Columbia, an Earth vessel which had disappeared in the Talos star group eighteen years previously. Arriving at Talos IV to investigate, Tyler was amongst the Enterprise crewmembers to be included in the landing party. Later, when it became clear that the distress signal was an elaborate trap set up by the Talosians in an effort to capture Captain Pike, Tyler participated in the unsuccessful attempts to rescue him.

Tyler's first name is based on background production references; the navigator described in the original Star Trek pitch is named "José Ortegas."
The Navigator. José (Joe) Tyler, Boston astronomer father and Brazilian mother, is boyishly handsome, still very much in the process of maturing. An unusual combination, he has inherited his father's mathematical ability. José Tyler, in fact, is a phenomenally brilliant mathematician and space theorist. But he has also inherited his mother's Latin temperament, fights a perpetual and highly personalized battle with his instruments and calculators, suspecting that space – and probably God, too – are engaged in a giant conspiracy to make his professional and personal life as difficult and uncomfortable as possible. Joe (or José, depending on the other party) is young enough to be painfully aware of the historical repute of Latins as lovers – and is in danger of failing this challenge on a cosmic scale.
The second revised final draft script of "The Cage" describes him as; "Mid-twenties, sometimes appearing even younger, very much in the process of maturing, both physically and socially. But beneath this exterior is a computer-like mind and strange mathematical brilliance."
