A visit to the new super-deluxe Bueno Nacho in Go City turns into an adventure when an fight breaks out between local villain Aviarius and superhero Hego (after a quick-change from his restaurant manager {{secret identity}}). Aviarius uses a staff to steal Hego's {{super strength}} for himself, but instead accidentally transfers it to Kim. Team Possible then assists Hego and his Team Go brothers against Aviarius, recruiting Shego (their sister and a former member of the team before she [[FaceHeelTurn turned evil]]) to help.

!!This episode provides examples of:
* {{Backstory}}[=/=]SuperHeroOrigin: Shego and her brothers were empowered by a [[MagicMeteor rainbow-hued comet]] that struck their tree house.
* BerserkButton: Do ''not'' accuse Shego of going "soft"....
* BlackSheep[=/=]FaceHeelTurn: Shego used to be a superhero working with her brothers until she quit. Hego's explanation is that she became [[EvilIsCool fascinated by evil]]; her own reactions suggest that she simply [[SurroundedByIdiots couldn't put up with them any more]].
* ConvenientlyTimedDistraction: Shego has gotten hold of the villain's power-stealing staff and taken all her brothers' powers for herself. Ron offers to distract Shego but Kim points out they would need a huge distraction, cue [[UnwantedRescue Drakken (thinking that Shego is in trouble) showing up]] with a [[HumongousMecha giant battle robot]]. This provides Kim the distraction she needs to break the device and return everyone's powers to their proper owners. At the end of the episode, Kim and Drakken notice that it was surprisingly easy to get the staff away from [[DangerouslyGenreSavvy Shego]], suggesting that [[ThickerThanWater she didn't really want to permanently steal her brothers' powers.]]
* DidYouActuallyBelieve: When Shego has a chance to grab Aviarius' staff and take all the powers for herself, she breaks her alliance with Kim, and mocks her for expecting anything different.
-->'''Kim:''' Shego, I thought we were in this together.\\
'''Shego:''' Oh, come ''on''. [[TheFarmerAndTheViper Don't you know me better by now?]] I mean, ''seriously''.
* DoesNotKnowHisOwnStrength: This happens to Kim a few times after the power transfer.
* EnemyMine: Shego gets roped into helping her brothers and Kim against Aviarius.
* KirkSummation[=/=]ShutUpKirk: After Shego grabs the staff, Hego tries to appeal to her better nature. It doesn't work.
-->'''Hego:''' No, I don't believe it. You may be a cranky smart mouth, prone to excessive violence, but deep down, you are still a member of Team Go... a hero.\\
'''Shego:''' Hego, I quit your stupid team years ago and after I quit, I went to work for a guy who wants to {{take over the world}}.\\
'''Kim:''' It's true.\\
'''Hego:''' But deep down...\\
'''Shego:''' [[PunctuatedForEmphasis I. Am. Evil.]] [[CardCarryingVillain Have I made myself clear?]]
* NoOntologicalInertia: Once Aviarius' staff is broken, everyone's superpowers return to the original owners.
* PowersAsPrograms: Aviarius' staff can steal and transfer superpowers.
* SiblingTeam[=/=]SuperFamilyTeam: Team Go.
* SlaveToPR: Kim threatens to publicize Shego's former life as a superhero if she doesn't help. Shego gives in rather than have her [[VillainCred reputation]] shot.
* ThickerThanWater: Both Kim and Drakken notice that it was surprisingly easy to get the staff away from Shego, suggesting that she didn't ''really'' want to permanently steal her brothers' powers.
* UnwantedRescue: Dr. Drakken, believing that Shego is in trouble, shows up in a [[HumongousMecha giant robot]] to rescue her. This creates a distraction that gives Kim a chance to get the staff away from Shego and destroy it.
* WeNeedADistraction: Ron says this immediately before Drakken shows up to provide one.
