Game Kingdom Hearts Union χ

Brain is a Keyblade wielder who appears in Kingdom Hearts Union χ. He is a member of the Dandelions and was chosen by the Master of Masters to lead a Union after the Keyblade War. Like the other new Union leaders, he was given a book with laws set by Master Ava.


Kingdom Hearts χ[edit]

As per Ava's instructions, the new Union leaders are to come together in the Keyblade Graveyard following the Keyblade War. Brain is the fourth to arrive, after Ephemer, Skuld, and Ventus, though he is surprised to see that he is not the last. Brain questions if the rules set forth by Ava are absolute, expressing his wariness to trust Ava because she wants them to lie to the Dandelions about the Keyblade War. Thinking of how Player had suffered, Ephemer states that no one else should have to carry the burden of the past, a sentiment Skuld and the others accept. Quest 675: Master Aced

After the final Union leader, Lauriam, arrives, the Union leaders go to Daybreak Town and enter the Foretellers' Chamber, where Brain finds a copy of the Book of Prophecies and starts flipping through it. When Skuld proposes that they begin choosing which Union each of them will lead, Ephemer recommends that they maintain the Union χ in order to prevent the conflicts of the past world, with the other Union leaders agreeing to reconstitute the old system later as stated in the rules. Brain then suggests that, while the Dandelions are reliving the events of the past, they collect the necessary ingredients to create new Spirits and sends Ephemer, Skuld, and Ventus to collect the ingredients while he and Lauriam stay behind to make the necessary preparations. Quest 735: The Shiny Hammer Pt. 5 Brain states that he is going to "become a virus that overwrites the program that is this world's future" in regards to the inevitable destruction of his world. Quest 860: Daybreak Fun with Ephemer Pt. 5


Brain is cool, calm and mysterious.


Brain has gray eyes and black spiky hair, which droops down over his eye. He wears a black coat with rolled up sleeves, gold buttons, and a large collar, grey pants, black cowboy boots, and silver cross-shaped earrings. His face is initially concealed by a black fedora that sports a black feather with a tan streak down the middle.
