Face of rebellion
The Exosphere is the outermost layer, 'Exo' is Greek for outside, there's no specific line where the Exosphere ends but we just refer to it as 'outer space'.
That's Se Hun for you, caught in his own Exosphere, mute and intellectually slow he's the worst excuse for an extra-terrestrial being. That's what every one says, they keep outside his Exosphere and no ones ever been able to get in.
And then there was Lu Han, the perfect being, beautiful features, the enhancing powers of telepathy.
Do opposites really attract?
Background history.
In outer space a army is forming, those on Planet Earth are equipped with nuclear power and apparent intelligence, those on neighbouring planets are laying low with the exception of Planet Mato.
Planet Mato, a horrible excuse for a planet, or so as MAMA says, the Planet consists of citizens who are a Class B Matoki. These species are Human kind species with a Matoki as their soul, they can regenerate into rabbit forms and constantly wear masks, (For purposes currently unknown.)
MAMA also commonly known as 'your majesty' is the big shot in EXO, she's a puppet behind a show, a wizard of OZ act. She rules the place yet no one has ever seen her in person behind the screen, the EXO planet is ahead of all the others, or so they think. Advanced in power and in abilities, 12 super-terrestrial beings have been created all to be wondrous beings ready for battle, except one and that one goes by the name of Se Hun.
