Fenrir

Fenrir was an Asgard who was exiled as punishment for the destruction of a populated star system when he did a unauthorized deployment test of a collapsar device he created. He was sentenced by the Asgard High Council to be put in stasis on his ship, the Aegis, which was then sent to roam the galactic clusters for five hundred seasons, on a course set to bring him back to the planet Hala when his sentence was over. His mind remained in a wakeful state so he could reflect on the mistakes his haste, arrogance, and belligerence had led to. However, in a stroke of bad luck, he found himself between the planet Heruun and a Wraith fleet preparing to cull its inhabitants when his ship dropped out of hyperspace to make a course correction. Fenrir and his vastly superior ship managed to win the insueing battle, but took in damage as a result and crash-landed on Heruun's moon. Stranded, with no way to fully repair his ship without help, he repeatedly kidnapped Heruun locals and temporarily brainwashed them to fix his ship for a duration of weeks, later sending them back home with their memories of where they had been and done in that time period erased.
