Robert Wesley (mirror)

In the mirror universe, Robert Wesley was a $𝜇$ male in the service of the Imperial Starfleet of the Terran Empire during the 23rd century.

By 2268, he had risen to the rank of commodore and was the commanding officer of the. During a war game held in that year, the $𝜇$ was put in command of the. It faced off against the Lexington,, the and the. However, when it was supposed to use low-powered phasers, it instead fired on the other ships at full power, destroying the Potemkin and nearly destroying the Enterprise.

Using an unorthodox strategy, the Enterprise's captain $𝜇$ and his first officer, $𝜇$, brought up the datacharts of the command consoles of the other two fully-crewed ships, knowing that M-5 would have changed the prefix codes of Excalibur to prevent what he was about to attempt. He armed the self-destruct package of both the Lexington and the Hood and detonated them when they were in close proximity to the Excalibur, vaporizing all three ships. Wesley was killed in the process, as were his entire crew.

The incident was reported to $𝜇$ as an accident but Spock correctly believed that it was an attempt to assassinate him by his enemies in Starfleet. M-5's creator Doctor $𝜇$ told Commodore Wesley that his creation could indeed destroy the Enterprise, but had not brought up the possibility that it would turn on them as well. Wesley paid for that mistake with his life.
