Angry Eyebrows

A normally peaceful or serene character wears a serious frown after getting quite a pummeling. Or maybe a fighter stops the common trash-talking chitchat.

If an enemy is unlucky, the camera will focus on the character's expression changing in a significant way, indicating they're about to go all out on them or die trying. If it's accompanying a physical transformation or costume change, it pretty much indicates the enemy is about to get owned.

Named after the very noticeable and atypical angry contorted face on an otherwise-normal character when this occurs.

Anime and Manga

 * Natsumi from Keroro Gunsou sometimes does the Angry Eyebrows.
 * Goku from Dragon Ball, especially in Dragonball Z.
 * Rurouni Kenshin - He even gets his face stuck in the "Angry" position because he'd been Obfuscating Stupidity and hadn't had the chance to glare at people for a while.
 * Luffy from One Piece plays this trope completely straight in his fight with Bellamy.
 * In the not very well known anime Shin-Hakkenden the main character, and for that matter all the jewel bearers, aren't noted so much for their facial expressions, but when one of their jewels glow...um...run away and you MIGHT survive.
 * In Flame of Recca when Recca fights the monk with the "Oni" artifact.
 * Kenshiro of Fist of the North Star has Big Ol' Eyebrows to begin with, but when he gets mad and glares, you know someone isn't walking away from the next fight.
 * Heaven help you if his Aloof Older Brother Raoh does it. He might just punch your head clean off, and that's being merciful.

Film
"Mr. Potato Head: Prepare to meet... MR. ANGRY EYES! AAAAAH!"
 * A rare example in Toy Story 2, with Mr. Potato Head. When they encounter the other Woody's Roundup Toys,


 * Subverted in that he actually puts on his spare shoes by mistake.

Live-Action TV

 * A rare live-action version is Sylar of Heroes. Whenever he's especially annoyed or pissed off, his eyebrows take on a life of their own. Of course, this is Zachary Quinto's eyebrows we're talking about.

Video Games

 * Ryu of Street Fighter and the anime film Street Fighter Zero Generation does it before going Satsui no Hadou Metameza Ryu after Gouki(Akuma) deals him a critical blow.
 * In Project Justice, the sequel to Rival Schools, there is an unlockable alternate version of Batsu called Burning Batsu, complete with powered-up attacks, ripped abs and Angry Eyebrows. You wouldn't like him when he gets angry.
 * Ryu in the NES Ninja Gaiden games would always sport Angry Eyebrows when he was ready to kick some ass during a cut scene.
 * Ristar originally only had angry eyebrows for boss fights; in the American version, they're present all the time.
 * Narcis Prince of Punch-Out!! will not let you touch his "beautiful, beautiful" face, so doing so is obviously his weakness, right? Yeah, except you just turned him into a British brawler, his "beautiful" face now has a growling sneer, and you better be quick on your feet if you want to beat him. That, or wait until he calms down ("Stay calm, matey!"). Luckily, his anger leaves his face exposed, allowing you to sock him in the face even more until he's knocked down.
 * Worms - the angry eyebrows are so iconic that when Team Fortress 2 cross-promoted it by offering a Worms-style helmet as a pre-order bonus, said helmet came with said eyebrows.

Web Animation

 * Strong Bad from Homestar Runner specifically added Angry Eyebrows to his dragon creation Trogdor to heighten his "majesty".

Web Comics

 * El Goonish Shive: This comic, last panel. Who knew Tedd could look so frightening?
 * The last panel of this Everyday Heroes strip, when Jane is sparring with Wrecking Paul and actually manages to hit him.

Western Animation

 * Western example: Aang in Avatar: The Last Airbender
 * Inverted with Zuko, whose usual expression is angry eyebrows. You know something's amiss when he has the eyebrow of mild worry.
 * Samurai Jack was a master of Angry Eyebrows, but they weren't always angry. Sometimes, they were just resolved, and always, always shown in close up. In addition, the eyebrows were sometimes shown after his gi had been shredded once again, combining the eyebrows with a costume change. Followed by ass-kicking.
 * Often used in South Park to express anger given the limitations of the animation.
 * Parodied in The Fairly Odd Parents. Timmy's Dad is mad at DINKLEBERG as a kid and wants to glare. Crocker comes by and pushes his eyebrows down into an angry face for him.
 * Ben 10 Alien Force - Ben does this right before transforming into some alien form to own whoever poses a significant danger to his friends and comrades.
 * An episode of Blue's Clues had Blue wanting to express an emotion (anger). One of the clues was a pair of "angry" eyebrows, and since the clues now sing for some reason, it lead to the hilarious image of some cartoon eyebrows singing enthusiastically "I'm scrunched-up eyebrows~"
 * Angry Eyebrows serve as Mooks in an episode of The Cartoon adventures of Larryboy. Seroiusly.
