Bienvenidos a Nueva Pekín, metrópoli central de un mundo futuro donde humanos, ciborgs y androides coexisten en precaria convivencia, amenazados todos por una extraña y caprichosa plaga mortal para la que los científicos no encuentran cura. Esa es la ciudad en la que vive Linh Cinder o, simplemente, Cinder, una ciborg que, por serlo, es odiada y despreciada por todos, y sobre todos, por Adri, su madrastra, cuyo amor y respeto jamás ha tenido a pesar de que gracias al trabajo de Cinder ella y sus dos hijas, Pearl y Peony, pueden salir adelante y aparentar más de lo que son. Aunque no todo son malas noticias: Peony es su mejor amiga. Su mejor amiga humana. Sabe que no lo logrará, pero no deja de alimentar la esperanza, que sabe vana, de ganarse el favor de su familia y de ir, ¿por qué no?, al baile real que cada año se celebra en Palacio. Pero es el cuento de nunca acabar porque Adri, que no deja de prometerle lo mejor para cuando acabe lo que sea que tiene que hacer, siempre le tiene guardada una tarea nueva, que arregle el levitador o cualquier otro cachivache. Porque Cinder es la mejor mecánica de Nueva Pekín, y tan grande es su fama que el mismísimo Príncipe Kaito, heredero de la Comunidad Oriental, ha acudido a su cuchitril en el mercado para confiarle el arreglo de su androide. «Contiene información confidencial y es una cuestión de seguridad nacional que la recupere... antes de que lo haga otra persona», le explica. Vale, Cinder es una ciborg pero no es de piedra, y ese príncipe se demuestra capaz de alterar todos sus circuitos. Pero se cierne sobre ella, sobre ellos, una amenaza más grave que el enamoramiento: la de una fuerza procedente del espacio exterior que aguarda el momento adecuado para atacar la tierra.
It's been years since the universe had seen the great Paladins of Voltron in battle. Years since those paladins have seen the lions. The universe was saved, so the lions left. Until now. The paladins are older now, and each have their own families. Hunk and Shay decided to settle down, and had a son named Erik. He looked a lot like Hunk, but was very Bulmeran. Shiro met an alien named Hel while on a special mission. The two fell in love and had a baby boy named Kade. Kade had black messy hair, and dark skin like Hel. Pidge didn't end up having any kids, but Matt on the other hand had a daughter named Evelyn. Evelyn was a lot like the siblings, with the same Gunderson charm. Lance settled down with Allura, and had a daughter named Isla. Isla looked very much like Allura, but with Lances brown hair and a strange condition with her skin tone. She ended up with a very light skin tone, due to a strange Altean occurrence. When no Altean father is present, the child takes the skin tone of the closest Altean male. Since that was Coran, Isla ended up with lighter skin, but Lance and Allura had no problems with it. Some time after Allura had passed away, Lance and Keith realized they had feelings for each other. They soon adopted a daughter named Abbey. Abbey had been through a lot regarding families, so she wasn't fond of siblings. Soon enough though, her and Isla became great friends. Even though Pidge had no children, all the kids thought of her as the cool aunt. They were all friends, and hung out quite often. This is the story of the Voltron Descendants.
(This is a story me and my friends are writing. The new characters are OC's of ours, and we wanted to do something with them. In this universe, Allura made it past the final battle, but passed away when Isla was young. All of the kids are fairly smart since Pidge educated them, but a few are more impulsive than others.)
