Summary
A remaster of Kingdom Hearts: Blue Blur Edition – Chain of Generations.
Shadow the Hedgehog is haunted by visions and a growing power within. His search for answers leads him to the ARK and the return of Black Doom. But the true danger lies in White Space, where echoes of his creation awaken forbidden power.
Aqua, still burdened by being a Nobody, searches for Ventus and a way to restore the Land of Departure. But her path too is pulled into White Space—where Mephiles the Dark, armed with the Phantom Ruby, sets his sights on rewriting this new timeline.
Together, Shadow and Aqua must stop Mephiles and Black Doom, rescue lost worlds, and guide displaced allies like Maria, Gerald, Terra, Silver, Cloud, Tifa, Elise, Orbot, Cubot and more.
Meanwhile, Sonic’s birthday is cut short when Terios, tied to a shadowy Organization, scatters his friends through twisted versions of the past. With the help of the man in red and some unexpected allies, Sonic must race through time to stop the Organization's plans and save his friends.
All three heroes face a deeper mystery: missing memories and a forgotten trio who once saved the universe.

Summary
¿Qué tanto estarían dispuestos a llegar por un sueño?
¿Qué tan alta sería la montaña que deberían escalar? ¿O que largo y ancho el mar? ¿O que basta y peligrosa la ciudad o el país? ¿Qué tan antiguas serían esas ruinas o lugares del pasado?
Pues esas cosas poco le valen a Miguel Rivera (tataranieto del de la película) Que con objetivo claro u una ambición a partir de un sueño de la niñez, no parará hasta ver sus sueños cumplidos. Ya sea ser una estrella en el mundo de la música, tener al padre que nunca tuvo o... demostrar a todo el mundo que la magia es real.
¨No importa que, lo voy a conseguir, y lo haré en grande. El camino al sueño imposible para demostrar a todos que el mundo más allá del sueño es tan real como cualquier otro¨.
(Historia Higuel, posibilidades de crossovers conforme vaya avanzando la trama) (y de paso posibles emparejamientos)
