Chrono Cross features twelve endings, two of which can be had on a normal playthrough (the other ten being accessible through a New Game +. Similar to Chrono Trigger's, Cross's endings reflect on humorous situations or what might have happened if the game had truly ended at the point a particular ending was accessed. Because of this, the endings seem to fall outside the realm of canon, but the more serious endings do offer insight and character development at times.
Savestates for use with ePSXe of all the endings are available here.
This ending can be had by playing a regular New Game and defeating the Time Devourer without using the Chrono Cross. It simply rolls the credits after the Devourer is absorbed into a strange portal above the Darkness Beyond Time.
Chrono Cross Ending
If the Chrono Cross is used to defeat the Time Devourer, Schala will break free and quote a long speech concerning the struggle of evolving organisms against each other. She then tells Serge that she will find him someday; he awakes on Opassa Beach, where he seemingly loses his memory. This is a point of interest, and analysis on it can be found in the Theory section.
If the Time Devourer is defeated before Serge crosses the dimensions, this ending results. All the major developers populate Viper Manor, and hilarious exchanges and notes about the game are provided to the player. Contrary to popular belief, there is no special Key Item to be had here, and neither can Kid be ushered to pickpocket a man in one of the rooms. She still changes uniforms to her orphanage outfit under certain conditions, and whether other changes can be made is under investigation. Please contribute if you can get the room location modifier codes working.
After crossing the dimensions, but before breaking into Viper Manor, this ending is available. Serge has become a fisherman in Arni, while Kid loses her patience waiting for him. She breaks into Viper Manor alone, takes down Lynx, and receives the Frozen Flame (which is actually the Dragon Tear in this scenario). She wishes herself Lord of El Nido, and creates the Acacia Empire by vowing to conquer the Kingdom of Guardia, and then Porre.
The True Hero (Without Kid)
While Kid is incapacitated after the Viper Manor break-in, this ending can be achieved. Serge works in Termina at Lisa's Element shop, and a biting exchange takes place between Lisa and Leena. Later, Kid is seen working in Viper Manor as a spy with Norris, who gave her the Hydra Humour. Afterwards, Solt, Peppor and Pierre are seen surmounting Fort Dragonia, the latter member of the group afflicted by stomach problems. Before they enter the sanctum, they begin a game of rock, paper, scissors in order to see who goes in first. Pierre loses, and complains for a rematch. The game then reveals that they were never heard from again.
The True Hero
The True Hero is the former ending, save with Kid in good health and the Korcha marriage dialogue having taken place. Instead of Kid working in Viper Manor, she enters Lisa's Element Shop after Leena and is insulted for not qualifying for a beauty pageant in Termina. Korcha then enters, attempting to reforge his wedding vows with Kid, but ends up proposing to Macha, who enters as Kid leaves.
The Magical Dreamers
Before attacking Fort Dragonia, this ending can be had if Nikki is in the party and Razzly was acquired as well. Kid must also be in good health. The player sees Lisa and Leena rushing to see the Magical Dreamers, who now have three new members; Serge is a percussionist, Kid is a vocalist, and Razzly is the band's mascot. After the concert fades, Lynx is seen exiting Fort Dragonia.
This ending occurs if the Time Devourer is beaten after Serge receives Lynx's body. Lynx now lives in Marbule with Harle, and the villagers adore him; the Sage of Marbule then asks him to take his position in a few days. The ending cuts to Radius, Zappa, and Fargo in the Pearly Gates. They confront Lynx and vow to make him pay for his crimes, but Kid drops down from the ceiling and promises that they won't have the chance.
This ending can be had if the Time Devourer is defeated right after rescuing Riddel, but not after going to Hermit's Hideaway. The Acacia Dragoons are all assembled in Viper Manor, and Viper decrees that they will depart to fight Lynx's army across the land. Taking the battle to the SS Invincible, the Dragoons eventually corner Lynx, who taunts them. The scene cuts to Lynx and Harle, who are still living in Marbule; Kid accosts them at their house, and Harle prepares to fight her.
The Darkened Fate
This ending is available after Harle leaves the party. Lynx and Kid enter Chronopolis; the former proceeds to the Frozen Flame, while Kid stays behind to deal with Harle, who is trying to stop the duo. The scene cuts to Arni, wherein an old man is consulting the Record of Fate. It turns a black color, alarming the man, who rushes out to get the chief. The scene returns to Lynx, who muses that he can now finally become FATE.
A Career Change...
This ending is available after Dario is fought, but before Terra Tower rises. In Viper Manor, the kids of the orphanage stand at attenetion to General Viper, who instructs them to work hard and play hard. An Acacia Dragoon talks to Dario and suggests a Dragoon youth camp; the two laugh as they formulate a plan to provide funding. Later, the scene cuts to Lynx, Harle, and Kid arriving in Termina. They enter The Dragon's Tail bar, which is now staffed by the Devas and Luccia. Lynx and Kid order Galaxy Nights, while Harle orders coffee, Denadoro Mountain Blend. After the drinks are served, two of Starky's race meet and decide that since the planet has no unique characteristics, their plan to destroy it must begin at once. Lynx is then given a huge bill, and when he enters the consultation room to dispute it, Zoah stands ready to mug him.
Return of the Downtrodden
This ending is available while Terra Tower is still in the sky. The Sage of Marbule, the Dwarf Chieftain, and the Dragon God have met at the top of Sky Dragon Isle. The Dragon God instructs them to begin wiping out humanity in El Nido with their respective forces; the Dwarf is eager to do so, while the Sage questions this course of actions. Nonetheless, it is carried out, and Demi-humans now populate the islands. Harle walks around Arni, overhearing conversation concerning how filthy the humans were; she then picks flowers and lays them on the grave at Cape Howl.
