Sev

Sev was an elite clone commando who was part of Delta Squad during the Clone Wars.

History
During the Clone Wars the commandos of Delta Squad were dispatched to Devaron in the aftermath of the battle waged there and recovered the bodies of Jedi Halsey and his Padawan, Knox, and returned them to Coruscant. The squad was met on the landing platform by Jedi Council members Obi-Wan Kenobi, Plo Koon, Saesee Tiin and Adi Gallia, who noted that the massacre was of similar caliber of the damage done by Asajj Ventress who was presumed dead. Security footage of the battle was recovered and included a hologram of Halsey's death at the hands of an as-yet unknown assassin.

Behind the scenes
Sev and Delta Squad first appeared in the 2005 Star Wars Legends video game, Star Wars: Republic Commando During development of Witches of the Mist, a season three episode of Star Wars: the Clone Wars, supervising director Dave Filoni requested that the team incorporate Delta Squad into the plot. The episode guide for Witches of the Mist brought Sev's Legends name (but not his original identification number, "RC-1207") into the new canon.
