Take a cartoon, preferably an older one, and find a pair who always end up in fights. Tom and Jerry, Dick Dastardly and Muttley from Wacky Races or virtually anyone from Looney Tunes. Somehow, one character always has a fist which can stretch across an entire country. Or a universe. This is a type of Toon Physics, and is often used with revenge. The inverse is when a character has extendable legs. Not to be confused with Rubber Man Needs a Better Description
- In A Growing Affection, Shino's damaged leg is replaced with an insect colony. They mimic a Human leg almost perfectly, but he teaches them to perform an extending kick.
- Jack, from the Calvinverse, has these.
- Zany To The Max: Inverted with Takko Zarner, who has extendable legs. His legs are usually longer than Yakko's.
- In an exceedingly rare live-action example, in the Chinese kung-fu movie Master of the Flying Guillotine, an Indian fighter enters a tournament with the power to extend his arms to an absurd length.
- Michael Jordan uses this to make a slam dunk in Space Jam.
- Freddy briefly extends both his arms to scare Tina in the first A Nightmare on Elm Street (1984) film.
- In Little Nemo: Adventures in Slumberland the Nightmare King uses his extendable arms to chase Nemo down tunnels in his flying bed.
- This is one of Dhalsim's special abilities in the Street Fighter series—he can punch you from the other side of the screen.
- In Sonic Unleashed, Sonic has arms that extend in his werehog form.
- Used as Bravoman's primary power along with extending legs.
- The main character of Ristar is able to do this as one of his main powers.
- The Pokémon Breloom can do this according to its Pokédex entry. The console game animations show it quite well.
- Hitmonlee is the inverse, with legs that stretch to enhance the power and range of its kicks. Bruno of Pokémon Special has a unique Hitmonlee that is capable of both.
- In The Thief and the Cobbler, the Witch uses this to pull down a hesitant character (who is much bigger than she is) for examination.
- Tom and Jerry demonstrates this several times, often when Tom tries to reach for Jerry inside one of the walls.
- Often used in conjunction with strategically placed mousetraps.
- Used by Dick Dastardly whenever Muttley starts laughing at him, outside the range of a typical human being.
- Pinkie Pie from My Little Pony: Friendship Is Magic has these, but she uses them to pull her friends in for a group hug.
- On Family Guy, Lois's father once punched Peter through an email.
- Though it doesn't involve combat, the mid-1980s Scooby-Doo series had Daphne restrain a fleeing Shaggy by extending her arms from off screen.
- Mr. Tickle from The Mr. Men Show does this to tickle people.
- In the original books, his arms were long all the time. In the show, they're usually normal sized.
- Other characters do this, but they do so to grab items from far away (but not as far away as Mr. Tickle can reach).
- Lucky in the 101 Dalmatians: The Series episode "Chow About That?" extends his arm off-screen to grab Cadpig. This does not occur in any other episodes.
