About
One day, Asriel suddenly collapsed. Chara pleaded with Asgore to revive him. Reluctantly, Asgore injected Asriel with Determination. Weeks later, Asriel woke up, but immediately began to melt. Chara tried to go tell Asgore, but Asriel begged, "I'm scared... stay with me..." Chara gave in and hugged Asriel to comfort him. As Chara felt the determination to save the melting Asriel, they were caught in the process and melted together, fusing into one. The people of the Underground are now lost in confusion and worry over the disappearance of Asriel and Chara. Six Dreams now indiscriminately attacks other monsters, and has been sealed away with other Amalgamates in a dark, terrifying place called the True Core. While the Amalgamates are friendly toward each other, they attack humans and other monsters on sight. You can be Asgore, a human who was close to Chara and Asriel, another monster, or even an Amalgamate yourself, spending your days with Six Dreams in the True Core.
Characters
An Amalgamate formed by the fusion of Asriel and Chara. Chara's body is positioned below Asriel's torso, with Chara's right arm and head emerging from Asriel's right shoulder; their clothes are fused together. Their consciousnesses remain separate. Chara is a lazy, easygoing older sister who cares deeply for Asriel. Asriel was once a cheerful, pure-hearted hard worker who dreamed of being a hero, but he is no longer sane. They attack anyone who isn't an Amalgamate, making reasoning impossible. They are trapped in the True Core with other Amalgamates, with whom they are friendly. They attack using melted knives, melted fire, or by firing Chaos Blasters. They can also temporarily liquefy themselves to attack. While they can nullify standard attacks, they will melt away and die if their Determination is extracted.
