Season 0: The killing game was set in Wonderland (unknown location in England). It was class 177B that were tricked into joining the game. It was all staged, it lead to Bloody Sunday, a massacre that ended up killing everyone in the class, but the killer, "Adelais Huntington", brought them back to life as cyborgs just to play with them as her toys. SHe was behind the scenes and let her AI servants lead the game until only five survived (Freya, Alise, Michi, Lacy, Orinoko). Freya, the only survivor, was kept human because Adelais has a weird thing (unknown feelings, her favorite plaything). The other four were trapped in Wonderland for a few months.

Season 1: Although someone had tipped off Hope’s Peak about the deaths of class 177B, it didn’t stop “Adelais” and Clarke from continuing on with their further plans (introducing Clarke to the story the head banana of the games). A new group of students were tricked into meeting up and hopping on a flight to Japan, only to crash down in Oz, Australia. Come to find out, Chiyo Shinrigaku was pulling strings behind the scenes. Mohee Grey was then found out to be an experiment done by Clarke turning him to something close to a monster. Freya had also returned and is in fact alive. In the end; Aries, Mohee, Kira, Shijima and Eva were rescued by the REAL Adelais Huntington & her Soldiers of Hope. Corinne Martel was taken in on the despair side after accepting immunity from Chiyo earlier in the game, who succumbed to death by Faker for his failures. Corinne's immunity was the ruby heart of the Tin Man. (written by Logie56)

Season 2: After Clarke's plan now in full effect, the entire world was enveloped in despair, forcing the ultimates of the world to go under protection programs for their own safety. One group was hijacked and taken to an abandoned candy factory where they had their killing game. Fiore was the mastermind (part of the group Other Direction) betraying his closest friend Tazio. Futsushi was able to escape the factory, but his fate is still a mystery. The only survivors were Alexis, Tazio, and Yashiro, who were all saved by the Soldiers of Hope. Fake Adelais escaped. Fiore and the AI servants left, leaving behind the leftover intelligence of Adelais's little brother William. Blanc, one of the AI's had left Addy a gift from Corinne, the ruby heart she had from her season. Inside the heart was a video game. During the game, however, Addy was attacked by robots of Clarke's and given a threat to stop her organization. It is known that Clarke had killed off her entire family and turned them into AI servants Blanc, and Mad Hatter, her father Marcus Huntington's death and what happened to his body is unknown.

~S0 survivors were also saved by Addy and SoH

Season 3: This Season was part one of the Huntington Arc, a past arc on how Clarke came to be 10 years before the season 0-2 (and only months before the Huntington family was murdered). He had lied to the participants that they were getting their talents removed. Instead they were left on the Island of the Dolls in South America left to kill, unless they promised to keep their talents. The survivors of the season were Itsumi, Kobe, Hae, Mun, Greta, and Kuni. Erio Wishaly was not only the traitor, but an experiment done by Clarke forced to be the mastermind to save her "brother" Moheegan (Mohee). Erio has connections with Mohee (a fellow experiment) and both her and Clarke were on the island to collect special rubies to help run Wonderland (S0) and to help with his experiments (s1 and Mohee) for the Moheegan project. The survivors were able to leave the island but it is unknown if all of them survived or not. Clarke and Erio were able to leave but also with the ruby from the island causing the island to sink. It also turns out Clarke was the ultimate lucky student, and saw himself as a useless ultimate, and envied the people who wanted to get rid of their talents. Kuni was able to recover a locket of Addy's parents which was later seen in present day with Addy after spending days playing the game Corinne gave her in season 2. Addy has just finished Level 1.
