CC-7567 (Powerstaark)

CC-7567, more commonly known as Rex, was a Clone Lieutenant and later Captain who served under Anakin Skywalker during the Clone Wars. After the death of Captain CC-77, also known as Fordo, on Yavin IV, Rex led a successful mission to rescue several Jedi trapped on Hypori from the clutches of the vicious cyborg General Grievous. Because of his success, Rex replaced Fordo as Captain of the 501st legion of clones and continued to fight alongside Skywalker and his Padawan Ahsoka Tano during the Clone Wars.

Early life
Like all Clones, CC-7567 was cloned from the legendary Bounty Hunter Jango Fett and was raised and trained on Kamino. He proved himself to be very talented in combat and became the Clone Lieutenant of the Torrent Company, in the 501st legion, under Captain Fordo. Like many clones, Rex fought during the Battle of Geonosis and survived.
