Wesley Crusher (mirror)

In the Mirror universe Wesley Crusher was the son of Jack and and served on the I.S.S. Enterprise-D in the Terran Empire's final days of a war with the Klingon-Cardassian Alliance. While most humans on the Enterprise blamed Vulcans for their Empire's misfortunes Wesley saw how Captain Picard had destroyed his family and that had tried to offer another way of life for the Empire, and befriended, a Vulcan who was serving as a slave on the Enterprise. He and Selar later fought together in the Terran rebellion (The Final Days, The Gift).

Selar had tought Vulcan mind techniques to Wesley, whose own understanding of the relation between space, energy, and thought enabled him to overcome his human limitations and perform mind melds with both humans and Vulcans. When Wesley was killed he gave Selar his katra. Selar hoped to give him life again by giving his katra to his Federation counterpart, but Ambassador Spock convinced her to reclaim the katra and take it to Vulcan. Through a mind meld with Selar Beverly Crusher saw the life Wesley led in the mirror universe and was deeply moved.
