One of his trades is exchanging his youth with a wealthy man's old age in return for one million dollars.

This briefly prevents them from using their powers, which was [=PallaPalla=]'s intent.

* ''WesternAnimation/TheRenAndStimpyShow'': The episode "Who's Stupid Now?" has the eponymous duo going through a PersonalitySwap that, as a side effect, causes them to trade physiques as well. So the LeanAndMean Ren and the FatIdiot Stimpy become FatIdiot Ren and LeanAndMean Stimpy.
* In one episode of ''WesternAnimation/TotallySpies'', the VillainOfTheWeek runs an agency that kidnaps supermodels and uses a contraption which switches their body parts with other womens'.

This trope can be thought of as FreakyFridayFlip meets PartialTransformation. Indeed, the boundary between this and FreakyFridayFlip can be blurry if two characters swap enough traits to be mistaken for the other -- and the number of traits that need to be swapped for that to happen can be low in certain illustrated and animated works where [[OnlySixFaces characters don't look vastly different from each other to begin with]]. And regardless of how thorough such a swap is, if the two characters also trade social roles as a result of the transformation it can become a LiteralTransformativeExperience as they discover what it's like to be in the other person's shoes.

* On ''Website/DeviantART'', the "attribute swap", "role swap", and "age swap" tags (among others) are used for depictions of characters exchanging physical traits. The most common variations involve two female characters with some connection to each other (usually a mother & daughter duo, but it can also be a teacher & student or boss & younger employee among other pairings) who magically switch ages and physiques and frequently also decide to trade social roles as well.

* In one episode of ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'', Grim and Billy decide to switch places for a day, with Grim going to school and Billy filling the role of TheGrimReaper. Initially, they only swap wardrobes, but eventually they start changing physically as well, with Grim becoming a fleshy, bulbous-nosed human and Billy becoming a [[DemBones skeleton]].

In action-focused works, the characters will likely swap whatever traits will give them an advantage in battle, such as switching with a stronger character's muscles for greater offense or switching with an iron-hided character's carapace for greater defense. More prosaic comedies and dramas instead tend to pair this with characters who [[IJustWantToBeBeautiful want to look more attractive]], such as a character with HeightAngst stealing the desired height from someone taller or a fat person with WeightWoe transferring the weight to someone thinner. Also, kids who want an OvernightAgeUp may steal the age from adults who [[FountainOfYouth get younger]] as a result.
