The Heart Symbol is a well-known symbol of love, peace, and life. You would think that they would always mean something good, right? But sometimes, they are used in association with villains for the sake of irony.
How the hearts are used may vary. Usually, all a villain needs is a costume decorated with heart shapes, or a heart-themed name. But in some cases, the villain is literally a heart-shaped creature.
Sometimes, the baddies who have this might have Love Freak and Heart Beat-Down as their schtick, but in a more twisted way. Another possibility is that it embodies Love Makes You Evil. A more justified version is when the heart is cracked/slashed down the middle, which usually symbolizes a broken heart and tragedy.
- Dio Brando of Jojos Bizarre Adventure has the Heart Symbol on his headband and knee pad, but he's the Big Bad of three parts of the story.
- Naruto: In a variant, Gaara has the kanji for "love" etched on his head with his sand powers, yet he's an Ax-Crazy kid. It actually stems from him being betrayed by his feelings of love as it contributes to his Dark and Troubled Past.
- The She-Hulk villain Captain Rectitude is a right-wing extremist who has a giant purple heart for a logo.
- Cats Don't Dance: Hearts are associated with Darla Dimple, who puts on a ridiculously sweet facade for her adoring fans, but turns out to be spoiled, jealous, and vindictive in private. In the second part of her Villain Song, which is a Disney Acid Sequence, hearts are seen everywhere, from the tips of the pointy fence that appears in one part, to the waterfall she imagines the heroes falling down.
- The Queen of Hearts from Alice's Adventures in Wonderland is a bad-tempered despot who often orders to execute her subjects. Adaptations of the book often turn her into the main antagonist.
- One episode of The Librarians 2014 has Prospero summon up a gang of Fictionals, including the Queen of Hearts, who wears a skimpy costume with a heart motif.
- In Kamen Rider Blade's playing card motifs, Kamen Rider Chalice is the Rider that represents the suit of Hearts. He's not a bad guy, per se, but he's an Anti-Anti-Christ and gigantic threat to everyone regardless.
- HIM: Their logo is a fusion of a heart and an inverted pentagram. The band characterizes their style as "love metal". One of the first songs they ever recorded was a cover of Chris Isaak's "Wicked Game", and prior to this the band used yet another symbol - a heart with 666 in the middle. Frontman Ville Valo, who designed the heartagram, later recalled this early symbol was "a bit boring". He later designed another one by crossing a heart with a unicursal hexagram, a shape made famous by occultist Aleister Crowley. He had it tattooed on himself for reference, but doesn't seem to have done anything else with it.
- In Lucha Libre, most post-1990 examples are in reference to Love Machine, an Evil Foreigner who wore a heart symbols on his mask before he was revealed to be Art Barr or to the Affably Evil extremo ATM, whose mask also has heart symbol shaped eye holes.

- Kirby: Planet Robobot:
- Unlike the final bosses of many other Kirby games, who are scary Eldritch Abominations, Star Dream is a massive supercomputer with a big heart icon painted on it. It also aims to destroy all organic life as it deems them inefficient and against order.
- As NOVA returns, so does its heart (See the entry for Super Star below), which you fight at the end of the True Arena. This time, the heart moves around and attacks you instead of just staying in the middle. And oddly, it shares a few attacks with Marx, another example of this trope...
- Kirby Super Star:
- Once he gains power from NOVA, Marx gains hearts on many parts of his body, especially his glistening wings. Did we mention that he's a psychotic, deceptively cute monster who manipulated Kirby into helping him gain said power?
- The core of NOVA is represented by a floating pink Heart Symbol. Kirby must destroy it to stop NOVA from granting Marx's wish for world domination.
- Queen Sectonia from Kirby: Triple Deluxe has, along with a heart emblem on her chest, tiny hearts adorning her sinister Requisite Royal Regalia. Fitting, considering how cruel and vain she is.
- Kirby Star Allies:
- The Jambastion mages and their leader Hyness have an emblem of a heart with demonic wings and a sinister eye on their outfits. It also features on the architecture of their bases, though not quite to the point of Sigil Spam.
- And then there is Void Termina. Aside from the sigil of Hyness' cult appearing on its armor, its mask/face is heart-shaped, and after growing wings, it also has a tail made of hearts. A heart pattern also runs across part of the shell that houses its soul, i.e his actual heart (which, ironically, is round-shaped).
- Kirby: Planet Robobot:
- The Legend of Zelda: Majora's Mask: The titular mask is a sentient Artifact of Doom with plans to destroy the world. And it's shaped like a heart.

- Kingdom Hearts:
- Emblem Heartless are identified by a black-and-red heart with a thorny X across the center, with an arrow pointing straight down.
- Riku's Dark Mode outfit has this emblem on his chest, except minus the X - it's just solid black with a red outline. Even after he completes his Heel–Face Turn, this symbol is the keychain for his own Keyblade.
- In Super Paper Mario, the Chaos Heart is an incredibly deadly artifact looking like a heart made out of mercury which can destroy every single universe in existence.
- Ricardio the Heart Guy from Adventure Time is an actual red heart with a face, arms, and legs. He manipulates Princess Bubblegum with the intention of cutting out her heart.
- Wander over Yonder: Lord Dominator wears a bleeding heart symbol on her shirt, which reflects her love for chaos and destruction.
