G.I. Joe: Sigma 6

G.I. Joe: Sigma 6 is a 26-episode animated series produced by the American company 4Kids Productions and animated by the Japanese studio Gonzo that aired between 2005 and 2006. Rather than the large body of characters that appeared in G.I. Joe: An Real American Hero, Sigma 6 went with a small team of soldiers. The leader was Duke with established characters Scarlett, Snake Eyes, Heavy Duty, and Spirit being part of the team; new characters included on the team are Tunnel Rat, Snake Eyes apprentices Jinx and Kamakura, Long Range, Lt. Stone and Firefly. Cobra has been streamlined as well, with Cobra Commander, Destro and the Baroness returning along with Zartan and the Dreadnoks and Storm Shadow. The show is largely man vs machine as the human Joes largely are challenged by Cobra who uses robot forces.

Showdown (Season 2, Episode 4)
Cobra Commander plans to steal a nanotechnology sample that is housed in the Central Museum and chastises Destro for coming late for this assignment. Destro explains he has been working on a project which Cobra Commander deems useless. The Joes move into the museum to stop the heist but walk into Destro's trap. They are overwhelmed by sound and then hit by Destro's project, the Brain Ripper, which put the subject under the control of Destro. All the Joes expect Spirit have Brain Rippers attached to their faces; Spirit challenges Destro only to see his team stand up and follow Destro's commands. Duke takes Spirit's arrow to shield Destro; then Duke and the Joes all prepare to shoot Spirit. Spirit can't bring himself to shoot his teammates; the Brain Ripped Joes fire on Spirit sending through a wall into the hallway, where a Brain Ripper attaches to his face and brings him under Destro's control. Hi-tec, the tech G.I. Joe, sees that the team is in danger and heads to the museum with his AI bot, HOUND. Hi-tec runs into the Brain Ripped Joes and flees; he jacks into the Cobra bots he is forced into and then uses them to fight the Joes, only to see the bots destroyed. He then recognizes that he might be able to apply the same jacking technique to free the Joes; the technique frees the Joes, which causes Destro to abandon the heist.
