Attie was a clone trooper during the Clone Wars who was part of the famed 501st Legion's Torrent Company.
In 22 BBY, Attie served under Jedi General Anakin Skywalker and Captain Rex during the Battle of Christophsis and later the Battle of Teth, where he assisted General Skywalker and his new Padawan, Ahsoka Tano, in recovering a kidnapped Huttlet. He scaled the cliff wall and defended against a second Separatist force, liberating himself from his droid captors along with his comrades. He was one of only six clone troopers to survive the mission.
As a male Human clone of bounty hunter Jango Fett, Attie stood 1.83 meters tall, and was born on the Wild Space planet Kamino.
Attie first appeared in the 2008 novelization of the Star Wars: The Clone Wars film by Karen Traviss.
