Kim convinces Ron to get a new haircut and calls in a favor from Francois the hair stylist. Ron is initially dismayed by the results, (since he feels the hair ruins his "essential Ron-ness") but gets a lot more confident after getting complimented on his new look by Amelia, an attractive senior. However, his hair refuses to lie flat, and Kim calls in another favor for a trip to France for more hair gel and a trim.
Soon after they arrive, the power starts going out all over Paris; Wade discovers that the problem is Europe-wide and traces it to a massive power drain at a location that turns out to be the private island of Señor Senior Senior. Kim convinces Senior to adopt energy-efficiency improvements so he'll stop overwhelming the power grid, while Ron takes in the sight of his mansion and compares it to a supervillain lair. After Team Possible leaves, Senior muses that he'd needed a hobby....
After an interlude of Ron enjoying his new popularity, Wade calls with the news that Senior is draining the power grid again, deliberately this time, and demanding that Europe turn over its "nice little islands". Team Possible returns, dodging the various death traps Senior has installed as part of his new villainous lifestyle. They stop the power drain, but the Seniors escape in a speedboat. Along the way, Ron's hair gets permanently mussed back to its old condition.
This episode provides examples of:
- Acquired Sitch Narcissism / Took a Level in Jerkass: Ron due to his new look, and this would not be the last time.
- Be Careful What You Wish For: Kim originally convinced Ron to get a new haircut to change him. But not only does he end up becoming vain and self-absorbed, it also leads to Ron convincing Senior Senior to become a villain.
- Big Blackout: The Seniors black out Europe twice — first by accident, then deliberately after Señor Senior Senior takes up supervillainy as a hobby.
- Chick Magnet: When Ron gets his hair gel'ed, girls start to notice him. When he completes his new look with designer clothes, girls stare at him as he walks by and he has group of girls staring at him dreamily during lunch.
- Eccentric Millionaire: The Seniors are established as this, even before taking up villainy.
- Fluffy the Terrible / Killer Rabbit: Mr. Possible tells Kim about the time in college he felt sorry for a lab rat, Pinky Joe Curlytail, (who "used to run mazes for those grad students, how I hated them"), and feeling bad for the little guy, built him a cybertronic battle suit with working plasma blaster. Unfortunately, he ended up running amok on campus, and a Flashback Cut shows people running from a laser fired by a robot piloted by a cute little mouse.Mr. Possible: (wistfully) Oh, Pinky Joe.
- Heel Realization: Whilst fighting with Junior, Ron realizes he's become just as selfish and self-absorbed as him upon seeing his reflection.
- Mundane Utility: Kim calling in one of her favors just to fly to France so Ron can get Le Goop.
- Nice Job Breaking It, Hero!: Señor Senior, Senior got the idea of taking up villainy as a hobby because Ron was so impressed by how much his mansion resembled a supervillain lair.Ron: Uh, okay, so I made a few suggestions, does that make it my fault?Kim: One hundred percent.
- Noodle Incident: How Kim saved Francois' poodle ("those dognappers had it coming") and how she helped the pilots land their plane by making a signaling light from stuff in the airport gift shop.
- Rhetorical Question Blunder:(Ron sees his reflection in the missile launch console)Ron: Look at me, what have I become?Junior: I do not know, what?
- Title Drop: At one point, Ron refers to himself as "the new Ron."
- Villain: Exit, Stage Left: As mentioned above, the Seniors escape in a motorboat (despite it being their island).
- Where The Heck Is Middleton: Señor Senior Senior makes a properly villainous threat to destroy Middleton, complete with a map◊ showing part of the western United States. The suggestion that Middleton is in Colorado (which is at the center of the map) is a fairly common bit of fanon, but later episodes gave other hints that don't square with this (or with each other).
- Wimp Fight: Ron and Junior get into a fight that mostly consists of deliberately mussing each other's hair.
