|Menchez in 2410.|
|Affiliation:||Klingon Defence Force|
Menchez was a Klingon Defense Force officer who commanded the IKS B'Cnah after he destroyed his previous vessel. He was well acquainted with the Captain of the USS Phoenix-X and, in fact, shared an exchange program between both vessels, in the late 24th century, where half of each crew served on the other's ship. (Star Trek: Phoenix-X, Star Trek Online: Literary Challenge)
In 2373, Menchez was suspected, by the Klingon Empire, of planning to ruin relations with the Federation. Instead, Admiral Daniel "set the records straight" and claimed Menchez as a "good man". In return, Menchez gave the USS Phoenix the Bochnah's cloaking device, which he was supposed to give to Hoglo, of the House of Duras. Menchez also agreed to an Officer Exchange Program between the IKS Bochnah and Daniel's crew, aboard the Phoenix, in which half of each crews would be exchanged between each other. ("Betrayal and Honour", "The Links' Traitor")
In 2375, Hoglo set into motion a plan to kill Menchez, by pitting Menchez against the Empire through framing someone close to him. On Stardate 52083.06, Menchez requested to rendezvous with the USS Phoenix-X, where Captain Daniel considered Menchez an old friend. There, Menchez warned Daniel that the Klingon High Council suspected Lieutenant Commander Red to be a traitor and had sent someone to assassinate Red. After capturing the assassin, Menchez joined the Phoenix-X aboard their ship as they investigated the matter to also clear Red's name. After infiltrating a facility with critical information, on Qo'noS, the Phoenix-X came under attack by Klingon ships from the Duras family. Instead of Menchez's death, as Hoglo desired, the enemies were defeated with the help of the Bochnah. Menchez was returned to his ship. ("Betrayal and Honour")
The following year, Menchez attempted to acclimatize Lieutenant Commander Red to his Klingon surroundings when the crew of the Phoenix-X was temporarily disbanded and Red was temporarily re-assigned to the Bochnah. ("Experimentalism")
In 2378, while en-route to rendezvous with the Phoenix-X, the Bochnah, where Menchez was in command, was attacked by a Borg cube. The attack ceased after their Changeling passenger, Shoon, was abducted and when Menchez beamed aboard the Phoenix-X, where a similar event happened with Shane, he pondered what the Borg wanted with two Changelings. Meanwhile, Menchez and Daniel discontinued the Officer Exchange Program between both ships, returning half of each crews' back to each ship. Later, while both the Phoenix-X and Bochnah trailed false signatures in an attempt to lure the Borg, Menchez expressed distaste for their plan. After a time of no results, Menchez chose to veer off and have the Bochnah look for the Borg themselves. ("Destiny's Revenge, Part I")
In 2380, Menchez was defeated in battle by a Reman ship which damaged his own vessel, the Bochnah, beyond repair. General Verticon approached in a Vorcha-class ship and gave it to Menchez. ("Forged in Something")
In 2410, Menchez and his crew were accidentally sent back in time to the year 2033 where they assisted in protecting the timeline from changes enacted by Sayjan. To do this, they were forced to ensure the Xindi-Avians were killed off. ("The Xindi Paradox")

- Menchez was role played by Hawku for the Star Trek Online: Literary Challenges in 2014/2015.
- Several characters from Star Trek: Phoenix-X share the same experiences from the video game missions of Star Trek Online. It is a soft-break of the "fourth wall" that they all are semi-conscious of this whilst interacting with each other. The only differing experiences between characters are depicted through in-story from the Star Trek Online: Literary and Unofficial Literary Challenges.
