Miles O'Brien (mirror)

In the mirror universe, Miles O'Brien was a slave of the Alliance until 2370. With the death of Benjamin Sisko a year later, he became leader of the Terran Rebellion. He was designated a theta by the Alliance and was given the name "Smiley" by Sisko, a name which stuck for years.

In 2370, he was working in the ore processing facility on Terok Nor when he encountered Julian Bashir. He and Sisko later helped Bashir and Kira Nerys escape. (DS9 episode: "Crossover")
