Cersei takes everything personally and responds with streams of barbed remarks and petty revenge.
Catelyn Stark's Mama Bear instincts often override her sense of reason and lead her to brash actions that work against her family in the long run, such as her impromptu capture of Tyrion and her release of Jaime, which were against the interests of both Ned and Robb, respectively.
Arya gets very openly angry about things she disagrees with in early seasons. As she gets older and endures more traumatic experiences, she slowly learns to restrain it to Tranquil Fury.
"Ours is the Fury" are the words of House Baratheon, and all the scions of that House are very headstrong and passionate about things that don't go their way.
Oberyn is enraged and ready to fight at the slightest insult even if he does remain calm and collected on the outside.
Brandon Stark, to the point where he was known, in the books, as the Wild Wolf.
The real life wrestler Warrior (That's his legal name, by the way) once went to a UConn seminar, and screamed lines like "Queering don't make the world work," and causing a near riot through his Hot-Blooded insanity.
He also, within two days of Heath Ledger's death was referring to him in public as 'Leather Hedger', although what he meant by that is, as always, anybody's guess.
The absolute insanity that was the "Macho Man" Randy Savage.
Kamen Rider was actually a pioneer of this in Japanese popular media.
Virtually every Red Ranger in Super Sentai. (Dekaranger's Ban takes it up to eleven, to the point that you wonder how - or if - he even sleeps.) Reds are powered by screaming, and going in without a plan because "justice is on our side!" is sometimes a deeply-held philosophy, with the point of an episode or two being Red proving to a more serious character that you don't need to waste time thinking, you just charge in. When the screaming begins, you know the Foe-Tossing Charge is coming! (Power Rangers is different, preferring the Ordinary High-School Student.)
Power Rangers Reds are less likely to be this, but there are exceptions, such as Jason. He's not so bad out of costume, but most of his morphed dialogue is shouted.
Kamen Rider Fourze is described as such is so Hot blooded it almost bleeds into Large Ham territory. Fans Theorize that the reason he tends to shed Manly Tears every now and then is because he is young and cannot properly control those emotions. Given the head writer previously worked on Tengen Toppa Gurren Lagann, this is absolutely no suprise.
24's Jack Bauer would like to remind you that he's A FEDERAL AGENT!
And that he wants everything done... NOW!
...because he is RUNNING OUT OF TIME!!!
The Practice ran on this trope. Bobby Donnell and Eugene Young were the front-runners, but most of the others did not run far behind. It was a rare courtroom scene that didn't contain one of them screaming at a witness... or the prosecutor... or the judge.
In Star Trek: Deep Space Nine, there is nothing Kira Nerys does that she does not do with every ounce of energy she possesses. On the very rare occasions we see her go into Tranquil Fury mode, things break. Like people. And buildings. And occasionally fleets of enemy ships.
General Martok, as a Klingon, is kind of expected to do this, but really, his every word sounds like a triumphant speech. Actor J.G. Hertzler invoked this trope during his audition, throwing a chair against the wall and losing a fingernail in the process. He impressed the Deep Space Nine higher-ups so much that they brought Martok back as a recurring character.
Prince Arthur from Merlin (2008). Whether it's sword-fighting, jousting, protecting Camelot, or falling in love, this guy does not do things by half.
Lieutenant Starbuck from Battlestar Galactica. While he prefers living an easy-life, all emotions go out once he's in the cockpit of a Viper. Or off-world dealing with Cylons, hostile aliens and one very evil Devil in Plain Sight. Or playing Triad against a rival.
David Starsky from Starsky & Hutch: impulsive and outspoken, affectionate and protective, passionate about every whimsical interest and exciting idea and opportunity that comes his way, inclined to make colorful, intimidating threats, and in possession of a notoriously ferocious temper and a tendency to back it up with a swift left hook to the jaw of whoever pissed him off. On occasion, he intentionally pushes this Up to 11 to manipulate a perp in a Good Cop/Bad Cop routine. However, it's actually when he calms down that things really start to get dangerous.
Junior from Pizza sure has a lot of energy for a apprentice chef.
Speaking of Andrew Ausage, his character Sole Umuga has this amount of energy with a Hair-Trigger Temper.
