Chára

Chára is a fictional character from the popular indie role-playing game Undertale, developed by Toby Fox. Introduced as a major antagonist, Chára is the first fallen human encountered by the player, whose soul is discovered in the game's opening. The player eventually absorbs Chara's soul after their own is taken by Flowey.

Throughout the game, Chára's backstory is gradually revealed through narrative elements and player actions. It is suggested that Chára was a human child who fell into the Underground, the world of monsters, and was adopted by the royal family. They formed a close bond with Asriel Dreemurr, the prince of the monsters. Their shared history is a pivotal part of the game's lore and influences the motivations of several characters.

Chára's presence becomes more pronounced as the player progresses, particularly in routes where the player demonstrates violent tendencies. Their influence is often depicted as a corrupting force, encouraging or amplifying the player's aggression. In the Genocide Route, Chára fully manifests, becoming the player's companion and guiding them towards the extermination of all monsters. Their ultimate goal and true nature are subjects of much fan interpretation and discussion. The character's ambiguity and role in shaping the player's experience are key aspects of Undertale's narrative design.
