He served as Captain Matthew Gideon's second in command for several years while they were assigned to an Explorer class ship. After the Drakh attacked Earth, Gideon was given command of the Excaliburand insisted that Matheson continue to serve as his XO. John was considered to be a role model among human telepaths since at that time no other has advanced so far in Earthforce. Telepaths have only recently been able to serve in the Earthforce Military since the Earth Senate dissolved the Psi Corps.
He had been a member of the Psi Corps for most of his life. During the Telepath War, he was ordered by Bruder, one of his superiors, to give sleepers to a captured leader of the Telepath Resistance, Alison. She convinced him to leave the facility he was in, as it was about to be attacked.
He served as second in command to Gideon on board an Explorer class ship. He was allowed on board the Excalibur after Gideon said he wouldn't go without him. Matheson helped find out where the distress signal from the IPX team led by Max Eilerson was coming from.
Attempted Alien Takeover of ExcaliburEdit
Gideon sent Matheson to find out what happened to a ship that was floating in space. He found the entire crew dead except for one person and a lot of strange writing on the walls. When the ship started getting taken over he objected to Gideon putting himself in harm's way. He also figured out, with the help of a clothes designer, that the aliens would do anything to save themselves. He then helped to kill the aliens.
Apparent Interference With An Alien CultureEdit
He and Gideon made first contact with a new species. The two aliens grabbed one of the guards and held up a gun. Matheson used his telepathic abilities to disarm and capture him. The aliens claimed the Earth has been interfering with their planet for years. Later when another alien came aboard to apprehend the other two he helped Gideon locate the aliens homeworld.
Medical Test to Develop a CureEdit
Senator Redway ordered the Excalibur to Earth on a classified mission. On the way they found a distress beacon but were unable to stop due to orders to reach Earth as fast as possible. Gideon ordered Matheson to capture the Starfury in the docking bay and use the gravitational deflectors to slow it down. The Starfury had Elizabeth Lochley on board. Later, in the battle with the Drakh, he participated by managing the defense grid.
Scan by Mr JonesEdit
During a mission spearheaded by Galen to locate the Well of Forever, Matheson was later scanned by a Mr Jones, a telepathic observer, according to the new regulations, but the observer looked into private sections of his mind too. The telepathic observer then told Gideon that Matheson would have to go back to Earth for an inquiry. Gideon said he was needed on the Excalibur but the observer said he had to go back. Gideon managed to get him to stay on the Excalibur by having Dureena Nafeel think about planting a bomb on the ship when she was in the vicinity of the observer. When the observer came to Gideon to report the threat, Gideon revealed it was all a fake out and that if he didn't let Matheson stay on board he would report Mr Jones' invasion of Dureena's privacy to the Earth Senate.
