Ron, desperate for respect, decides to become a "bad boy." Drakken, desperate to win, decides to attend a supervillain convention. But matters go bad when an accident with an [[MirrorMoralityMachine attitudinator]] turns Drakken mild-mannered and Ron into a supervillain.

!! This episode contains examples of the following tropes:
* AllGirlsWantBadBoys: Kim admits to Ron that she likes the TroubledButCute type. Ron sees a pattern, and attempts to cultivate a bad boy persona as date-bait. This coincides with a TransformationRay that makes him a genuine supervillain.
* AssholeVictim: It's impossible to feel sorry for Cousin Sean when Evil Ron tries to kill him with his plasma catapult.
* BeCarefulWhatYouWishFor: Upon seeing that Ron is a more credible supervillain than Drakken, Shego aims to trade up and get some results for once. She quickly finds that Evil!Ron is also a bigger threat than her and more than willing to prove it, [[ArsonMurderAndJaywalking and worst of all]], he did all of this to get the world to surrender its entire supply of nacos as ransom.
* BeingGoodSucks: Drakken is depressed when he figures out that becoming evil again for the greater good will mean no more playtime with Rufus.
* BetterTheDevilYouKnow: It's made pretty clear that Kim's job is a ''lot'' more difficult with Ron taking the helm as the BigBad.
* BorrowedCatchphrase: Shego borrows Ron's SickAndWrong catchphrase to describe Good!Drakken.
* BrattyHalfPint: Seven-year-old cousin Sean, who delights in tormenting Ron.
* BullyingADragon: Sean turns up to torment Ron, ignoring the big, scary-looking way he's refitted his trike and the fact that Ron is twice his size.
* CallBack: Ron being microchipped by Wade is referenced once again.
** One of the girls Ron unsuccessfully tries to hit on as a “bad boy” is Tara, [[Recap/KimPossibleS1E2SinkOrSwim the cheerleader]] [[Recap/KimPossibleS3E2EmotionSickness who had a crush on him once]], but she clearly preferred the nicer version of Ron, and has probably moved on.
* CassandraTruth: Ron's parents don't believe him about Sean being a little monster on the basis that he's only 7 years old. Kim initially thinks Ron is overreacting as well.
* DreadedKidsTable: Ron wouldn't dread it so much if he didn't have to sit with his cousin Sean, and he has to sit here unless he brings a date to the wedding. Kim offers to pretend to be his, which he takes her up on at the end of the episode.
* EnfanteTerrible: At least, that's how Ron sees Sean.
* EvilerThanThou: Shego quickly realizes, much to her horror, that Ron being a bigger threat than Drakken also means he's a bigger threat than ''her''.
* EvilIsHammy: Evil!Ron is possibly the most over-the-top villain of the series, which is saying something.
* EvilLaugh: Evil!Ron's combines this with his "Booyah!!" catchphrase. It quickly grates on Shego's nerves.
* {{Facepalm}}: Shego's response to Evil!Ron's ultimate goal being to claim the world's supply of Nacos.
* FightUnscene: Played for laughs, after Ron and Drakken's personalities are restored.
-->'''Drakken''': Aha, Kim Possible! For now it is I, Dr. Drakken, who controls the Mega Weather Generator!
-->'''Kim''': ''(smirking)'' I think we all know what comes next...
-->''[cut to Drakken's lair exploding]''
* FullNameUltimatum: Ron doing this to Kim at the reception is just one further way to show how he's become a supervillain. Him later using Kim's full legal name is derided as overkill.
* GettingSmiliesPaintedOnYourSoul: Subverted, as the Attitudinator wasn't specifically designed to make people happy, but both Good!Drakken and Evil!Ron come off as much happier in their adjusted forms than their normal ones.
* GoneHorriblyRight: Ron wanted to be a bad boy so he could get a date for the wedding and avoid sitting at the kid's table with Sean. Thanks to the Attitudinator, he ''does'' become a [[ExactWords bad boy]]. To the point he no longer concerns himself with getting a date, because he's invented a devious device that will ensure Sean bows down to him!
* InsultBackfire: Kim says Evil!Ron using her FullNameUltimatum is overkill, but he responds by saying overkill is exactly what he's going for.
* HappinessInMindControl: Good Drakken likes the way he is and doesn't want to be turned evil again. Kim convinces him to reluctantly accept it because it's the way things are supposed to be (politely avoiding the fact that Evil Ron is a much more effective and dangerous villain than Drakken was).
* HypocriticalHumor: Ron ribs Kim for watching ''[[SoapWithinAShow Agony County]]'', which she claims is only to stay current. Just a moment later he makes a remark about a previous episode of the series, revealing that he himself watches it regularly as well.
--> '''Ron:''' Am I not supposed to be current?
** Kim’s disbelief of Ron being tormented by his 7 year old cousin could be this given she herself is often tormented by her own 10 year old twin brothers. That said, the Tweebs are nowhere as bad as Sean.
* KidsAreCruel: Ron isn't exaggerating that Sean is borderline rotten to the core. Even Kim is in disbelief as to how snide the kid is when she meets him in person.
* LeaningOnTheFourthWall: Right after a ShipTease moment while Kim and Ron are watching a soap opera:
-->'''Ron:''' Are they still teasing that Charity and Danny are gonna get together?
-->'''Kim:''' Like that's ever happen! It would end the series.
** [[HilariousInHindsight Hilariously]], Ron and Kim getting together [[PostScriptSeason actually gave the show]] [[{{Uncancelled}} an extra season]].
* LesserOfTwoEvils: Turning Drakken evil again is a small price to pay for returning the much more dangerous Evil!Ron to normal.
* MirrorMoralityMachine: Ron is turned evil and Drakken good by the Attitudinator after it breaks.
* NoSell: In response to being called hired help, Shego tries to blast Evil!Ron, but it's deflected by a force field. He says he found the device in Drakken's stuff, but he doubts the guy even knew how to work his own invention.
* ObliviousToLove: Ron is oblivious to Kim's hints that she wants to be his date.
* PaperThinDisguise: Kim is less than impressed with Wade's disguises for Ron and her. Indeed, Shego isn't fooled for even a second when she come across "Zorpox the Conqueror" and "Sheila of the Leopard People" at the convention center. On the flipside, [[FailedASpotCheck Jack Hench is completely fooled and even tries to sell Ron a tank.]]
* RedemptionPromotion: Inverted with Ron. After being zapped by the attitudinator, he's effective enough to scare Shego into submission, smart enough to utilize Drakken's gadgets better than he ever could, multitasks two schemes at once and using his insight on Kim to plan in the event of what she'll be doing.
* SharkPool: Ron opens one behind Shego while telling her that "sidekicks need to know their place."
* ShipTease: Kim and Ron getting very 'awk-weird' when he suggests she could go to the wedding as his date.
* SideEffectsInclude: The commercial touts the benefits of the attitudinator, mentioning towards the end that it may cause hubris and itchy feet.
* SoapWithinAShow: ''Agony County'', a teen drama Ron and Kim watch "to stay current."
* SuperpoweredEvilSide: Evil!Ron shows much stronger focus and force of personality than normal Ron, to the point where he intimidates Shego into shutting up and obeying orders.
* ThereIsNoKillLikeOverkill: Ron's modus operanti through the episode after being turned evil. His first plot, an attempt to kill his 7-year old cousin Sean involves retooling his trike into an ATV that turns into a ''[[DisproportionateRetribution plasma catapult]]'' with which to blast him apart. His second scheme involves using his Annihilator to cause quakes that will shake the world to pieces unless it surrenders to him, and ''that'' was a decoy plan to cover up his Mega-Weather Generator - all so that the world will surrender the world's supply of ''[[TrademarkFavoriteFood nacos]]'' to him.
-->'''Ron:''' Overkill? Isn't that the idea?
* TookALevelInKindness: While it was helped along by the Attitudinator, in the end, Cousin Sean is turned into a much more pleasant person who treats Ron with more respect and kindness.
* UnEvilLaugh: Ron is fond of [[EvilLaugh laughing]] "Boo-yah-ha-ha-ha-ha!" Shego is noticeably in pain from hearing his "evil laugh" because it's so terrible.
* WeNeedADistraction: After Kim shuts down the Annihilator with two seconds to spare, Evil!Ron reveals that was just a decoy to buy time for him to finish his Mega-Weather Generator. Shego's rather annoyed over not being in the loop on this.
* WeWantOurJerkBack: Kim wants Drakken to let them use the attitudinator to swap Ron and Drakken back to normal because he is the lesser of the two evils. To be clear, she and Wade aren’t particularly annoyed by Good Drakken and they clearly don't enjoy the idea of turning Drakken back to his old self since he is their most frequent foe, but they have no choice in the matter, since having to deal with Evil Ron is much, ''much'' worse.
* WhyDidntIThinkOfThat: Evil!Ron boasts that he can track Kim's movements simply by scanning for the Kimmunicator's unique frequency. Shego is frustrated to realize how obvious that was and how Drakken never once thought of exploiting it.
