A specific form of Revenge, where a person receives the same bad treatment that they showed/were going to show to others. While it may be the original victim who delivers the punishment, it can just as easily be a relative or even a complete stranger.
Superficially, this might look like Beat Them at Their Own Game, but they are motivated by different factors and have a different meaning to the plot:
- Beat Them at Their Own Game is a survival technique. The person who successfully does it has proven that he can do whatever the other person did just as well.
- A Taste Of Their Own Medicine is a type of Revenge. The person who successfully does it has demonstrated why the other person should follow The Golden Rule.
The two tropes occasionally overlap, but, in general, try to list an example as one or the other. If you're not sure which it is, ask yourself whether the primary motivator is survival or revenge.
Contrast Hoist by Their Own Petard, which is where a character's bad actions lead directly to their downfall, with no second-party intervention. Often a form of Pay Evil unto Evil. An Ironic Hell is the extreme version of this, where the sinners are punished with being the victim of (or making them horrified with) whatever crime they've done before. Can overlap with Laser-Guided Karma if the character's fate is similar to that of his victims. See also Who's Laughing Now?, which sometimes results from applying this trope. Please note that Selective Enforcement and Hypocrite can pop up if the sinner makes a big show out of it.
- Bleach: In the manga, when Sado fights Yammy, the latter hits him so hard that the attack tears Sado's arm apart...twice!

- Freeza's entire fighting style revolves around Cold-Blooded Torture, physically overwhelming his enemies with his power and making sure that they die in pain and despair, knowing that they never stood a chance against him.

In the end, the only reason Goku tries to spare Freeza is because he felt that letting Freeza live with his pride ripped to shreds was a far worse punishment.
- This was Dr. Gero's intention with creating the androids. After Goku destroyed the Red Ribbon Army, he wanted to create a fighter that could beat Goku on his terms and inspire the same sense of fear and dread he gave the army.

Majuub tries to transform him using Majin Buu's Chocolate Beam, but Baby sends it back at him and devours him afterwards. However, it later turns out that Majuub deliberately let himself be changed and swallowed so he could attack Baby from the inside, incapacitating him with pain during his fight with Goku; Majuub even tells Baby that he's doing what Baby himself does to other people.
Majuub: Isn't that how you operate, Baby?! You lay your eggs in people and attack them from the inside!
- Dragon Ball Super:
- The first time Beerus meets Goku, he effortlessly defeats the latter with a neck chop. Later, when Goku's recieved a new powerup and they fight on something resembling equal ground, Goku repeats the neck chop to Beerus, pointing out the time Beerus did it to him.

Upon getting her Shadow Dragon, she commences in completely tearing each of the posse apart, the only one she spares being the one who objected to Aki raping her. And when she finally catches up to Aki herself? She has her raped with the Shadow Dragon's clawed finger, just before tearing her apart as well. By the time her vengeance is complete, Hiro-chan has gone into full Start of Darkness mode.
- Street Fighter II: The Animated Movie: During his fight with Chun Li, Vega makes the mistake of cutting her cheek then taunting her by licking the blood off his claw. Bad decision. She pays him back... with interest. First, by hitting him square in the face by throwing the couch at him, followed by repeatedly kicking his face with her Spinning Bird Kick, then pushes him back down on the floor by stepping on his chest, so she could plant her barefoot on his cheek and perform a full pirouette on his face! And, yes, it's as awesome as it sounds (seen at 5:07-6:03).
- Tokyo Ghoul: When Kaneki is tortured by Yamori after being captured, he's forced to count down from 1000 by seven over and over to keep himself sane so he can feel each and every cut. When Kaneki accepts that he's a ghoul and beats Yamori in a fight, he pins him to the ground and forces him to count down the exact same way. Yamori had also made clear his intention to eat Kaneki after he finally snapped, and Kaneki takes care to remind him...

- X-Men: In X-Men #112, Magneto, who had previously been transformed into a baby by a scheme gone wrong, gives the X-Men a taste of the same (even though none of the captured X-Men were involved in his infantilization). He locks them into chairs that not only inhibit their powers but also disrupt their neurological functioning so that physically they're at the level of toddlers but they retain adult intelligence. He then leaves them to the care of Nanny, an android with a sickeningly sweet personality to care for them as if they were babies. ("Oh Beast, you've such marvelous silky fur. You are a joy to brush. I've an idea. Would you like bows for your hair? I'll see if I can find some.") His intention is that they will live out the rest of their lives in that state, and it is implied that they are trapped that way for several days if not weeks before escaping.

She then compares this to how he felt with Chloe and Lila pursuing him, causing him to realize he made Ladybug feel the same way.

- In Mystery Skulls Animated, Lewis' revenge for his death at the hands of Arthur (possession of the murderer notwithstanding) is putting him through the exact same circumstances as he originally died. He recreates the cave where the fatal incident occurred, and forces Arthur to retrace his steps so he can fall to his death.
