Summary
La premisa básica de este AU es una fusión de Miraculous/Adventure Time, donde los personajes y el entorno de MLB se trasladan a Ooo y construimos el mundo en torno a ellos y como encajarían
No va a ser un fic propiamente dicho (aunque espero en un futuro cambiar eso) la idea es que la gente participe y aporte ideas u opiniones para dar forma esto
Tambien lo subire a Spacebattles sin embargo soy totalmente nuevo en esa plataforma y no sé muy bien cómo funciona el sitio. Solo lo he usado para ver los fics que suben en el apartado Creative Writing, así que si tenéis algún consejo sería de gran ayuda

Summary
Trying to live in a world that's been blown to bits is hard. Oozers everywhere, a giant skeleton man hellbent on destroying all life, mutagen everywhere, and now the vampires are making a move.
Life being this way sucked. But Lenore understood it was survival of the fittest at this point so survive she would, even if it meant staying as far away from other humans as possible for their protection. She could admit to being lonely, but it was easier this way. Until she come across an orphaned young girl no more then five who had been rejected by the humans for the possibility of being either a mutant or vampire with her strange looks. Unable to leave the child she begins a journey that could more then possibly led to a horrible end.
But hey she promised Marceline to stick with her.
Even if it meant dealing with the king of vampires.

Summary
Not much was known about humans from before the Mushroom War, the only one left who would know anything was an insane, sad old wizard. but when the hero of Ooo stumbles across an ancient dungeon filled with cryo-pods and another human, all of that could change.
Basically a /reader but with PLOT and also readers from before the mushroom war I guess. Sure hope that won’t cause any problems later ahaha…

Summary
What if? Del Capítulo "Solo magos, bobos no".
Abracadaniel fue a prisión por culpa de la Princesa Bubblegum, ella escapo y el fue torturado y abusado por los otros reos hasta que su mente se destruyó. Pero para un mago, la locura es la puerta a un poder de grandes alturas.
El Mago Maestro tras contemplar como, el delirante Abracadaniel, aniquiló a casi todos los prisioneros, decide que no desperdiciara la oportunidad de tener un asesino tan destructivo y lo manda a asesinar a Bonnibel, aunque es probable que asesine a todos los que se le atraviesen en el caminó. Abracadaniel solo quiere sembrar margaritas, con los cadáveres de sus enemigos. Pero también tiene visiones sobre un mundo alterno, dónde vive un hechicero de hielo, al que quiere servir y proteger como si fuera su dios.
Este fanfic ocurre en un Universo Alternativo dónde el Rey Helado lleva muerto y congelado 500 años.
Esta versión de Abracadaniel fue abusado por los reos, pero no sé describirá esas partes, ya que esta historia se pueda centrar más en el horror corporal, la locura y la manipulación. Aquí todo puede salir mal para todos los involucrados.
Abracadaniel sufre de Erotofobia, lo cual es un hecho canonico en Hora de Aventura.

Summary
Las aves gigantes atacaron la biblioteca de la Princesa Tortuga, varios amigos murieron ese día, pero para Simon Petrikov no solo fue ver morir a Abracadaniel, sino ver cómo momentos antes de su muerte, el mago arcoiris se sumergió hasta el fondo de la piscina de lágrimas hasta ser consumido por la locura magica, todo para salvar la vida de Simon.
Ya que después de todo, el Rey Helado siempre fue la persona más admirada por Abracadaniel, morir por su Rey, no hay mayor felicidad que morir por su amado Rey, ya que le ha pertenecido desde el principio de los tiempos.
Basado en la alucinación de Finn en Juntos de nuevo, no puedo evitar creer que era real hasta cierto nivel, aquí la triste historia de un héroe no reconocido.
Una historia sobre muerte, sobre locura mágica y sus consecuencias tristes.Series
