Kim is called for help from Dr. Drakken, but not; the voice isn't his, but of a Pvt. Dobbs. Drakken has used a brain-switching machine to trade bodies with Dobbs. Kim and Ron go to rescue Dobbs from Drakken's lair. While there, they battle Shego and accidentally get brain-swapped themselves. Meanwhile, Drakken has used Dobbs's body to get into a top-secret project area and steal a new military weapon. When he returns, he finds his new lair destroyed, so he and his henchmen move. While unpacking, he discovers that his body is missing, and he wants it back. While Wade tracks down where Drakken has moved, Kim and Ron get a good taste of what it's like in each others shoes: Ron being bullied and Kim being over-tasked. Wade finds Drakken, and Kim, Ron, and Dobbs return to Drakken's new lair to retrieve the weapon. After battling Shego, Drakken senses a loss and sets the self-destruct on his new lair. With mere seconds to go, Kim and Ron re-switch their brains. Unfortunately, Ron and Rufus get swapped. They re-swap and escape just before the lair explodes. Dobbs is in luck; the weapon is indestructible, and is unscathed in the midst of the debris.
