Hi, my name is a lifelong RPG player, and I have trust issues because of pixels. In 2026, we have ray tracing, 4K remakes, handheld PCs that cost more than my first car, and yet I still flinch whenever a smiling NPC offers to join my party. The epic betrayal is one of gaming's oldest tropes, and honestly, it works. A good backstab can redirect a story, reframe every kindness, and make me stare at my screen whispering, 'You absolute monster.' A bad one makes me shrug. The following betrayals? They ruined me. Some ruined me twice.

10. The Player in Undertale: The Betrayal Was Me 💔

Undertale is a game about mercy, second chances, and not judging a book by its monster. Then the Genocide route exists. I hunted every monster in every region until the Underground went quiet. I did it for curiosity. I betrayed the game's kindness, and it remembered. In 2026, Undertale still remembers. The game does not just judge you; it files a police report, calls your mother, and leaves a voicemail about your choices.

9. Yotsuyu Goe Brutus in Final Fantasy 14: A Two-for-One Special

Stormblood's Yotsuyu gets dethroned, returns as Tsuyu, seems redeemable, then her adoptive brother shows up and triggers her memories. She murders her parents. Then she becomes a primal. Then her brother kills her. That is not a betrayal; that is a betrayal combo meal with extra fries. As of 2026, FF14 has moved on to newer expansions, but Yotsuyu's tragedy remains a masterclass in making me feel bad for someone I absolutely should not trust.

8. Ghaleon in Lunar: The Teacher Who Was Secretly the Final Boss

Thanks to the 2025 Lunar Remastered Collection, a fresh batch of players can meet Ghaleon and make the same mistake I did. He sends you on a quest, plays the victim, joins your party at level 99 with fantastic gear, then reveals he is the Magic Emperor. I trusted him because he had good hair and a cape. I was a fool. A well-dressed fool, but a fool.

7. Dimentio in Super Paper Mario: The Clown Who Played Everyone

Dimentio shows up as one of Count Bleck's minions, which is already a red flag the size of a flagpole. In truth, he was never loyal. He was using Bleck to gather the Chaos Heart so he could remake the world in his image. His betrayal comes at the very end, and he becomes Super Dimentio. It is like if a jester pulled off his mask and revealed he was also the stage, the theater, and the bankruptcy lawyer.

6. Sephiroth in Final Fantasy 7: The Developer-Orchestrated Heartbreak

Sephiroth's betrayal is not just in-story. It is the developers betraying me personally. Aerith is a staple healer. I leveled her. I unlocked her best weapons and Limit Breaks. Then Sephiroth does the thing. In 2026, with the remake trilogy still unfolding, new players get to experience that loss in high definition, with better graphics and the same crater in their chest. I still have not emotionally recovered, and I have a spreadsheet of coping mechanisms.

5. Mercer Frey in Skyrim: Never Trust a Thieves Guild Boss

Skyrim has been re-released on every device except maybe a microwave, and in 2026, people are still joining the Thieves Guild. Mercer Frey seems trustworthy because Oblivion's guild leadership was mostly fine. Then he betrays everyone, kills people, and forces me to put him down. The lesson? When your boss says 'trust me' in a sewer, update your resume.

4. Riku in Kingdom Hearts: My Best Friend Took My Keyblade

Riku is my rival, my friend, and then the guy who steals my Keyblade and my Disney sidekicks. In the first Kingdom Hearts, he races me, trains with me, and then Maleficent corrupts him. When he shows up in Hollow Bastion and takes Donald and Goofy, I felt like a kid whose best friend traded him for a cool cloak. Kingdom Hearts 4 may still be a rumor in 2026, but Riku's first betrayal is canon forever.

3. Seymour Guado in Final Fantasy 10: The Creepy Proposal

Seymour is introduced as a villain, but he helps the party briefly, so I let my guard down. Then he proposes to Yuna. Then we learn he murdered his own father. Then he tries to murder everyone and kidnaps Yuna to force her to marry him. Then he keeps coming back to life. Seymour is the RPG equivalent of a bad penny that also wants to marry your summoner. His betrayal is not shocking, but it has style, and style counts.

2. Arthas Menethil in Warcraft 3: The Prince Who Became the Problem

Arthas is the archetypal modern gaming betrayal. You play as him in Warcraft 3's human campaign. You watch him purge Stratholme, lose his humanity, take up Frostmourne, and kill his own father. Then he becomes the Lich King. In 2026, World of Warcraft has traveled to new expansions and new continents, but Arthas still casts a long, icy shadow. He did not just betray his people; he betrayed the entire concept of a heroic protagonist.

1. Delita Heiral in Final Fantasy Tactics: The Worst Best Friend

Delita is Ramza's friend, confidant, and eventually the guy who erases him from history. After his sister dies, Delita decides to trust nobody and manipulate everyone. He helps Ramza sometimes, but also puts him in worse positions, forces him to uproot the church, and gets him branded a heretic. Delita becomes king of Ivalice. Ramza becomes a footnote. And when his wife, Queen Ovelia, questions him, he stabs her. Delita is the friend who borrows your car, crashes it, and then becomes president. I am still mad.

So there you have it. In 2026, I still play RPGs. I still trust the guy with the cool armor. I still get betrayed. And I still come back for more, because when a betrayal is done right, it is not just a plot twist. It is a memory. Now if you will excuse me, I need to go level up a healer and pretend everything is fine. 😄
