Attack Backfire

"They say they hate me; they wanna hold me down. I guess they're scared of the rebel; the rebel of the underground!

But I never let it get me.

I just make another record 'bout the punks trying to sweat me!"

- Tupac Shakur, in Rebel Of The Underground.

This is for when something that is used against a particular character is either beneficial and/or pleasant to that character or at least perceived by that character as such.

Subtropes include:
 * Feed It with Fire: When use of fire as a weapon benefits those it is used against.
 * Infernal Retaliation: When setting the enemy on fire allows it to burn you with it.
 * Insult Backfire, at least when there are pragmatic intents behind said insult.
 * No Such Thing as Bad Publicity: Kicking up a fuss over controversial works tends to play right into their authors' hands.
 * Threat Backfire: Threatening something that X wants anyway.
 * Too Kinky to Torture: When torture is what one intends to do to character X, who ends up enjoying it anyway.
 * Unishment: When what is used to punish X happens to be what X wanted anyway.

See also Shooting Superman, where rather than backfire it does what the audience expects: nothing.

Anime And Manga

 * In Dragon Ball GT, Goku tries to take down Super 17 with a variety of ki-based attacks, only to discover that he can increase his strength level by absorbing them.

Film
"Jarvis: Power at 400% capacity. Tony: How bout that?"

 * In The Fifth Element, the big dark planet of evil is attacked by Earth's military with several rockets. Instead of the rockets hurting it, they cause it to get bigger.
 * Tomorrow Never Dies gives us Mr. Stamper, whose insides are rewired so that any intended painful action he receives (such as stabbing with a knife) gives him pleasure. Conversely, any intended pleasuring action he receives (such as tickling) gives him pain.
 * In the 2012 The Avengers movie, Thor blasts Iron Man with a bolt of lightning. The effect on Tony's suit?


 * This could be a nod to the fact that Tony's arc reactor is based on the Tesseract technology of, possibly, Asgardian origin. As is Thor's Mjolnir.

Literature

 * In a gamebook from the Grail Quest Solo Fantasy saga, there's a sort of humanoid insect that you can fight. However, despite having only 25 health points, each of your attacks will give him more health. However, he'll let you go if you give him enough health points.
 * In one of the Blood Sword gamebooks you could try dealing with a huge Djinni by blasting it with the Orb of Fire. He finds it refreshing and it doesn't end well for the character attempting it...

Live Action TV

 * In the Doctor Who episode Vincent and the Doctor, the Monster of the Week seemed to enjoy the sonic screwdriver.
 * Buffy the Vampire Slayer: The Big Bad in season four got a rush off of the Initiative's electricity guns.

Music

Newspaper Comics

 * When Calvin and Hobbes fought the Snow Goons, they tried throwing snowballs at them, but that just allowed them to grow bigger.
 * This Garfield strip had this happen to Garfield, with Jon Comically Missing the Point of what Garfield was actually trying to do.

Video Games

 * In Final Fantasy II, attacking enemies with the wrong spell (eg Ice monsters with Ice magic, Undead with Drain and Osmose or Blob Monster with Poison) will actually heal the monster. In case of Drain or the Blood Swords results will be ugly.
 * In fact, all Final Fantasy games after the first one have a system of elemental absorb.
 * In the Super Smash Bros. games, Ness' and Lucas' PSI Magnets absorb energy projectiles (i.e. Mario's fireballs, Samus' charge shot) and heal by the amount of damage the attack would have caused.
 * In Street Fighter 4, Zangief gets a victory quote against Blanka informing him that his electric blasts helped relieve his back pain.
 * The Pokémon abilities Volt Absorb and Water Absorb not only make Pokémon with these abilities immune to Electric- or Water-type attacks respectively, but also heal them by one-quarter of their maximum HP each time they are hit by attacks of the corresponding type.
 * This trope is pretty much what makes Shin Megami Tensei games earn their reputation as fiendishly hard. There are too many monsters that have the ability to absorb one or more elements that yours character can use, and there are too few attacks that are guaranteed deal meaningful damage all the time. On top of it, some games have a system that gleefully punishes you for using the elements the monsters absorb.
 * In Minecraft, throwing a Splash Potion of Instant Damage at a zombie or skeleton will heal them. Likewise, throwing a Splash Potion of Instant Health will hurt them

Web Comics

The Pharoah comments that Ra must be rewarding them for punishing their slaves.
 * SpongeBob SquarePants: Mermaid Man mistakes Spongebob for evil and attacks with his trademark Water Balls. Spongebob enjoys it, because as a sponge, he absorbs it.
 * One episode of Godzilla: The Series had some hispanic army use a biological weapon against the Monster of the Week, but it turns out to strengthen it. Then they try it again.
