In Cobra Kai, fights break out for any reason at all. Someone could get their pride hurt or want a payback, or just want to prove they are tougher than the other guy. The show loves to remind everyone that rules mean nothing when anger takes over. Karate lessons start out simple but turn into grudges that follow these kids everywhere. A lesson in discipline becomes a hallway ambush or a cheap shot that leaves someone broken. Some fights twist what karate is supposed to stand for until it feels rotten.
Every dirty move leaves a scar that does not fade. A rigged match or a blindside hit can ruin a friendship or push someone down a path they cannot come back from. The series does not hide the lengths people can go to when they decide that mercy makes them weak. Fights stay unfair because someone always wants the last word or the last hit.
A fair match in the dojo feels rare when cheap shots win trophies and bribes buy victories. The worst fights do not happen under bright lights but in dark corners, when no one is ready. These Cobra Kai moments stick because they show just how fast respect can vanish when revenge takes over.
Cobra Kai: 8 fights that were rigged, unfair, or just plain wrong
1) Hawk vs. Brucks (Dojo Tryout)

Hawk faced Brucks during a sparring round that Kreese turned into a test. Brucks never stood a chance once Hawk knocked him down and got on top of him. He hit Brucks again and again while Kreese watched from the sidelines.
Brucks begged Hawk to stop, but Hawk refused. Kreese wanted Hawk to show no mercy, and that is exactly what Hawk did. He kept swinging until Brucks could not even lift his head from the mat, as blood covered the floor where he was lying, groaning.
That day turned Hawk from bullied Eli into someone the whole dojo feared. His old weakness vanished the second he stood up to Brucks and broke his face. This beating locked him deeper into Kreese’s world, and the line between fighter and weapon was gone. Hawk crossed it and never looked back. No one forgot that moment. Everyone saw how far Cobra Kai could push a kid to prove he belonged.
2) Tory vs. Sam (High School Brawl)

Tory did not plan a fair fight. She waited for the first day of school to corner Sam and make it public. She stormed the halls, ready to spill blood if that is what it took.
Wearing a spiked bracelet hidden on her wrist, she used it like a blade and dragged it across Sam’s arm until blood soaked her shirt. That single cut turned a grudge into chaos. Classmates watched the fight explode across lockers and down the stairs.
Tory wanted revenge for losing Miguel. She wanted Sam to feel real fear and real pain. Sam’s scar never faded, and neither did the panic that gripped her for seasons after. This hallway brawl broke any hope that the feud would stay inside the dojo. When teachers dragged them apart, the damage was already done. Tory proved she would never fight fair if anger called for blood.
3) Robby vs. Miguel (High School Brawl)

Miguel and Robby clashed in that same fight that started with Tory’s ambush. They were not supposed to be enemies, but anger pulled them in too deep. They traded kicks and blocks like they had something to prove.
Miguel pinned Robby down first but showed mercy. He stepped back and lowered his guard. He thought letting Robby go would end it, but Robby snapped. Robby hit him with a roundhouse out of nowhere. Miguel fell over the railing and slammed his back on the stairs.
Doctors stated Miguel might never walk again. Although Robby ran, the guilt stayed with him every day after. Johnny and Daniel realised how their lessons fed that moment. That kick broke Miguel’s spine as well as the trust that took years to rebuild. The balcony fall changed the whole rivalry from teenage karate to life and death. Nobody who watched forgot that fall.
4) Hawk vs. Demetri (Arcade Fight)

Hawk found Demetri at the arcade and dragged him into a corner away from help. Demetri never wanted to fight, but Hawk did not care. His Cobra Kai crew circled them, so Demetri was unable to run.
Hawk slammed Demetri to the floor and pinned his arm down. Demetri begged him not to do it. Hawk looked him in the eye and snapped his arm clean while the others cheered. The crack echoed through the arcade, and kids screamed when they saw the bone break.
Demetri and Hawk were best friends once, but that moment killed it. Hawk walked away, but regret hit him too late. Demetri’s cast became a mark of what Cobra Kai turned Hawk into. That broken arm pushed Hawk to see what Kreese was really teaching. This fight planted the seed that made Hawk leave the dojo later. Betrayal started right there on the sticky arcade floor.
5) Hawk vs. Robby (2018 All Valley Semifinal)

Hawk and Robby stepped onto the mat at the All Valley with rules that should have kept it clean. Robby scored the first point, and Hawk lost it the second when the ref called a stop. Hawk did not step back.
Hawk struck Robby from behind with a cheap kick that slammed Robby’s shoulder hard enough to pop it out. The ref threw Hawk out for fighting dirty. Even his own teammates stared like they couldn't recognise him anymore.
This disqualification cost Hawk a shot at the title and proved that Cobra Kai’s fight style did not care about honor. Robby’s shoulder stayed hurt for the final against Miguel. The cheap hit set up Miguel’s win and left Robby limping through every move. Hawk’s kick showed everyone how Cobra Kai taught loyalty, but only when winning was guaranteed. One illegal blow ruined trust in front of a whole arena.
6) Miguel vs. Robby (2018 All Valley Final)

Miguel and Robby faced each other right after Hawk’s foul play. Robby’s shoulder throbbed, but he stepped on the mat anyway. Miguel knew the shoulder was shot. He did not hold back.
Miguel hit the same shoulder again and again. He drove Robby to the floor every time Robby tried to get back up. He did not stop until the ref held up his hand as champion. Johnny looked proud for a moment, but it faded fast.
Johnny saw that his student won by digging into someone’s weak spot instead of fighting straight. The win should have felt big, but it felt hollow. Miguel’s victory forced Johnny to question what Cobra Kai was really teaching. The trophy on Miguel’s shelf became a reminder that the dojo cared more about hurting an opponent than showing real skill. That final was not a win. It was a warning.
7) Tory vs. Sam (2019 All Valley Final)

Sam and Tory met again at the next All Valley. Both wanted a clean shot to settle scores. Terry Silver decided they would not get one. He bought off the ref before the match even started.
Sam scored hits that got ignored. Tory threw elbows that should have cost her points, but the ref called them clean. The match dragged on while Silver smirked from the stands. Tory lifted the trophy, but her face said she knew the truth.
The fix made the whole tournament feel fake. Tory tried to believe she earned it, but the lie followed her home. This crooked win pushed her to look past Cobra Kai’s fake promises. She saw how easy Silver turned fighters into pawns. The final that should have closed a chapter left everyone wondering if honor had any place left in the dojo. The bribe won the fight. Nothing else did.
8) Terry Silver vs. Stingray

Stingray begged to rejoin Cobra Kai even though he was too old and too soft. Terry Silver saw a chance to get rid of Kreese once and for all. He did not tell Stingray no; instead, he told him to take a beating.
Silver cornered the Stingray in his own apartment. He hit him over and over until Stingray was unable to stand. He left him battered on the floor and then told him to lie. Kreese got arrested for a crime he did not commit.
Stingray’s broken face became proof of how far Silver would go to own Cobra Kai alone. Stingray thought loyalty would protect him, but it made him the perfect scapegoat. When Stingray finally confessed the truth, the damage was already done. Silver’s ambush demonstrated that Cobra Kai under him was not about karate. It was about power at any cost. One beating turned loyalty into fear forever.
