People don't always keep the same number or shape of limbs during a story — that'd surely be boring. So sometimes, a character ends up getting completely new limbs, possibly of a type they've never used before. They can also just get a temporary extension to their body; either way, it's a chance for them to explore new sensations and abilities.
This gives the creator a chance to show off their descriptive skills, explaining new things the character feels and how they're using their reshaped body. This page may contain spoilers if a character only gets new limbs or a different form at the end of the story.
The body parts can have been changed through someone shapeshifting, getting Artificial Limbs, being cursed, or just randomly Sprouting Ears. On occasion, the person has a whole new body instead, which may or may not be used for hilarity if they're naked. When downplayed, this trope is simply a character using their existing limbs in a new way or finding new sensations.

- In the Osamu Tezuka manga Dororo Hyakkimaru, the swordsman who Dororo travels with, was magically mutilated as a child, and so is made mostly of artificial parts.

- Adaptations and reboots also play with it a bit more. For example, the very first thing Hyakkimaru does when he first reclaims his eyes in the Dororo to Hyakkimaru manga reboot is... immediately develop an eye infection.
