Kangaroo Courts held in various Anime and Manga.
- A young Edgeworth calls this out by name in the English dub of Ace Attorney (2016) (a franchise very well known for this trope to begin with), shaming his entire class that believed Phoenix was guilty of stealing his money without any proof.
- The Magic Parliament in Black Clover is entirely comprised of aristocrats and the legal authority of the Clover Kingdom. They're very willing to condemn Asta and Nero due Nero's wegs, a sign of her use of Forbidden Magic, and Asta for being a peasant. They're led by Damnatio, who knows Asta is innocent but would rather have him be blamed than the Magic Knights.
- Bleach:
- The Central 46 is one which rules all Soul Society. Rukia is condemned to have her soul destroyed simply for temporarily giving her powers to a human to save both their lives. True, Captain Aizen murdered the Central 46 and used mind control to make everyone think they were still following orders from the court, but it speaks volumes that no one questions the fact that Central 46 apparently just decided to straight-up execute someone for a crime that is essentially a misdemeanour. The only thing that sets off any alarm bells is how she's to be executed. And when the entire military is mobilized to stop Rukia's friends (literally just five kids and a cat) from trying to save her, with immediate kill orders rather than any attempt to negotiate with them, the head of the military (who is the closest figure to Central 46 and has been taking orders from them for millennia, so should know exactly what they're like) doesn't question the absurdity of this for even a second until after the truth has been revealed and the Soul Society as a whole has been compromised. The implication is that this kind of utter unreasonableness is par for the course.
- The Turn Back the Pendulum arc shows that yes, Central 46 really are that unreasonable in truth. In Urahara Kisuke's sham of a trialnote , he's not even told what he's being arrested for until he's already been dragged in chains into the courtroom and is having the accusations hurled at him, isn't allowed any sort of defence against the charges, isn't allowed to see the evidence against him, isn't allowed to speak except to answer questions (and all his answers are met with ridicule), and is shouted down and has his sentence increased simply for trying to explain his version of events. In the same trial, the victims are sentenced to death not only in absentia, but before they even regain consciousness, without any questions asked about whether they're actually dangerous at all. The entire "trial" also shows Central 46 as essentially being a bunch of shouty, emotionally-driven, self-righteous nobles who are outraged beyond reason by even the slightest hint of supposed disrespect. Apparently, disrespect includes "wanting your side of the story to be heard" and "being horrified that your friends are going to be needlessly executed" so good luck if you ever end up in their courtroom.
- Aizen receives similar treatment, being sentenced almost immediately. When he lightly mocks the Central 46, they add two thousand years to the sentence and have his eyes covered so he'll be blind the entire time. In this case though, his crimes against Soul Society (and the rest of humanity, dead or alive) were actually legitimate with plenty of eyewitness and first-hand evidence. The sentence would have included an execution if he wasn't immortal at that point. Still, Central 46 added an extra two millennia and enforced blindness to his sentence essentially for the crime of not bowing and scraping to the people who were sentencing him to an And I Must Scream situation.
- And of course, the Vandenreich, who are actually the precursors to the Nazis. One of them 'judges' the Arrancar at the Hueco Mondo outpost by ordering them into a linear formation, and then chain-killing them one at a time while pronouncing "GUILTY" for each one. His coworkers laugh a little at the obvious insult to every form of trial ever.

- Code Geass:
- Suzaku Kururugi is arrested for murdering Prince Clovis and is screwed from the get-go due to being Japanese. He actually goes back after Lelouch rescues him and does him a solid by confessing to the murder. Say what you want about him, the man walks the walk.
- In Turn 19 of R2, the Black Knights do this to Lelouch as a prelude to a mutiny. Schneizel, a Britannian prince, sets up a meeting knowing in advance Lelouch won't attend (because Nunnally is presumed dead). He then proceeds to tell them that their leader is an exiled Britannian prince with Geass, as well as a laundry list of crimes they think he's used it for. The only evidence presented which has a shred of credibility is a voice clip in which Lelouch supposedly admits to causing the SAZ massacre (the part where Suzaku calls him a liar is omitted). Ohgi comes in with another Britannian, Villetta, and claims this is all true. Everyone believes him. They make a deal to trade Lelouch for Japan, trick Kallen into walking Lelouch into a crossfire, then nearly gun them both down. Kangaroo Court at its finest, and Kallen even points it out to absolutely no effect. The Compilation Movie version changes this a bit by depicting the Black Knights as being more reluctant and cautious about their decision, attempting to be more reasonable by having Lelouch answer some of their questions first before deciding what to do with him. It's Schneizel and his group that attempt to shoot him down before that can actually happen, leaving them with no idea what to think anymore and causing them to simply roll with what happens next.
- Combattler V: In one episode of the first season, the Big Bad built a Robeast disguised like Combattler and caused havoc with it. Professor Yotsuya and the Combattler team were put under arrest and judged nearly instantly, and during the proceeding it was painfully obvious the minds of the court were already made and refused giving them a fair hearing.
- In the beginning of Deadman Wonderland, Ganta, a little boy who was the only survivor of the Red Man Massacre, was arrested and tried for the crime. They wouldn't allow him to speak and quickly sentence him to Deadman Wonderland. It should be noted that his lawyer is the owner/director of Deadman Wonderland, though Ganta and many of his clients don't know this.
- Other kangaroo trials include a little girl who was left to die by her mother and went mad, a cowboy cop who tried to be a superhero, and some psychopaths who actually committed murder, but are clearly not guilty by reason of insanity and need a mental hospital rather than a brutal prison. The main reason for this level of kangaroo-hopping is because these people are actually infected with a substance that gives people superpowers, and DW wants to exploit these people to hell and back. Eventually, they infect the decoy prisoners who are guilty of regular crimes and accuse THEM of being infected from the start.
- In Final Fantasy: Lost Stranger, Shogo and his friends are accused of attempted murder of Princess Sara after Shogo pushes her off the clock tower to get her out of the Magus Sisters' grasp, knowing full well that Lukahn's Gaelicat Levitate magic would slow their fall in time. But after Sara tries to clear their names, Gershwin storms in with a direct order from the king for their capture, and the court ends up completely skipping the trial altogether and sentencing them to hanging. Due to the Mysidian nobility's disdain for outsiders, they don't even think of hearing them out until Sara once again intervenes on the heroes' behalf and calls out her father for his complicity in this.
- Little Witch Academia (2017): In episode 8, while Akko is traveling through Sucy's mind, she comes across different types of Sucys with their own personalities who want to be part of the real Sucy that are arrested by police versions of Sucy and taken to court. The judge and jury are all Sucys and judged every one of them guilty. When Akko points out that the entire trial is unfair to all the Sucys and their desire to be part of Sucy isn't a crime, she is pronounced guilty and sentenced to death.
- Mazinger Z: In one episode The Dragon Baron Ashura had trapped The Hero Kouji Kabuto and decided "judging" him, playing judge, jury and executioner.
- Nadia: The Secret of Blue Water: In episode "To the Sky..", Gargoyle subject Nemo to this to 'welcome' him aboard the Red Noah, accusing him of treason against Atlantis. Quite naturally, Judge Gargoyle will not allow any lawyers to speak for the defense in his Courtroom; God sees through all defenses, after all, and he's God. The Grandis Gang are also conscripted as the Witnesses and the brainwashed Nadia and Neo serve as Gargoyle's Executors of the Judgment.
- One Piece:
- Montblanc Norland was put through one 400 years ago. After reporting his discovery of Shandora, the city of gold on Jaya to his king, the king wanted to "check it out" for himself. When they got to Jaya and found that there was no city, gold or otherwise (Having been blasted into the White Sea by the Knock-Up Stream), the king put Norland on trial for deception and had a ringer pose as a member of Norland's crew, who "testified" that Norland was lying about the Shandora. To add insult to injury, a later fable based on this scandal depicted Norland as a grinning fool and the king a brave warrior.
- There is Kangaroo Court set-up at Enies Lobby, with the ironically-named "Eleven Just Jurymen", a jury of condemned criminals who, due to being on death row themselves, would only say "Guilty!" out of pure spite, and Chief Justice Baskerville, an insane giant three-headed judge. Though they were never actually shown trying anyone, acting more as a bunch of Giant Mooks. In fact, Enies Lobby has such a high conviction rate that most people don't believe there are trials- the common myth is that criminals just walk through an empty courthouse on their way to either Impel Down or Marine Headquarters.
- Panty and Stocking from Panty & Stocking with Garterbelt are put on trial in "1 Angry Ghost" for murdering an innocent ghost. They are given a monkey for a lawyer and the judge let them show how they work due to how vulgar their transformations are. It turns out the trial was set up by Scanty and Kneesocks who are only found out because the monkey gets shocked which give it heightened intelligence that allows him to uncover the real culprit and reveal the demon sisters' ruse. Even the judge ends up giving in and lets the Angels be as vulgar as they need to be after the real culprit attacks him.
- In Soul Eater, Kid and company face this when they enter the Witch realm to ask for help in Moon battle. They're tied up and brought to the court when they expected a talk, and are given no chance to defend themselves. By the way, the court doesn't give anything other than death sentences. The session culminates in sentencing Kid a million times to death for being a shinigami.
- Simon gets put through one of these in Tengen Toppa Gurren Lagann when Rossiu needs a scapegoat. Kittan angrily protests at the verdict, pointing out, among other things, that they gave Simon the stupidest (or at least tied for stupidest) member of the government for a defense attorney and packed the court with members of Rossiu's government (with Rossiu himself presiding as judge).Rossiu: Quiet in my courtroom, Legal Affairs Chief Kittan.
- The court system in Wizard Barristers that's used to try "magic users", dubbed "wuds". Wuds only get the very fundamental rights, like the right to a "wizard barrister" to defend them, and are tried during a single court hearing. If they're found guilty and sentenced to death, they're executed on the spot.
- The kangaroo court antics reach their peak in the final episode. A bizarre series of circumstances leads to the courtroom roles being completely swapped around: The defense attorney is trying to prove the defendant guilty, the prosecution is trying to prove the defendant innocent, whiles the defendant himself is trying prove "prosecute" his attorney.
