Spock

Legendary 23rd Century Starfleet officer and 24th Century Ambassador idolized by the RommaVulc Commander Prosak of the USS Anomaly.

According to history, Spock mysteriously disappeared in 2387. In truth, he was trying to use Red Matter save Romulus from the Hobus supernova. As far as he knows, he was too late to save the planet, and then he was attacked by Nero. Both his ship, the Jellyfish, and Nero's ship, the Narada, were sucked into the black hole that resulted when the Red Matter was put into the Hobus supernova. These events are detailed in the 2009 Star Trek film directed by J.J. Abrams.

What Spock and Nero don't know is that they were both transported to an alternate universe before they even got to Hobus by the crew of the USS Anomaly. (We'll Always Have Romulus [BG])
