Tokoyami and Dark Shadow
they to everyone were host and sentient quirk
but to them they were twins
and the ancient gods of destruction, night, moon, and darkness, voids, controlling them all with ease
they had only come down to earth because they were quite interested in the humans wanting to explore and learn more about them and the world they live them, so they decided to disguise themselves as normal teens so they could try out new things
They were quite interested in this Hero and quirks thing so both deities went down.
Both of them are very powerful, Tokoyami took "shadow manipulation" to be his quirk and Dark Shadow who was actually called Yaseikage to be his "shadow demon transformation"
Fumikage Tokoyami had hidden his true form, but he would normally have red eyes, long feathers (4 feet longer than his own body length) and fangs instead of teeth
whilst Yaseikage only hid his normal length feathers,
yaseikage was more social than his twin,(which they didn't hide even in disguise) a little bit heavier than his brother, and half an inch taller than him, and the oldest by a minute.
Fumi is quiet and peaceful while Yasei (or just Kage) was rather loud and chaotic
while the two had their disagreements and differences the two cared for and loved each other as brothers should
especially shown when helping to protect a world from a devil
while many devils used their destructive powers to make peoples lives miserable, destroying for the fun of it, seeing innocent civilians bleed to death as a type of entertainment
both tokoyami and yaseikage used their destructive powers for the good of all kind, to rid of evil and their mistakes
while yaseikage was always the least mature of them, tokoyami taking charge and being the brains of the team, he was always the stronger and more protective of his slightly younger brother
so when tokoyami was crumpled onto a worlds grass, blood soaking through his battle clothes, yaseikage to far away to stop the devil who had crumpled tokoyami into the ground, yaseikage's power had doubled in power, rage and protectiveness surging through his veins to finish this war
within one swipe of his claws, he summoned the stars and meteorites onto the devil until his own black brother began to leak into the ground
"little brother!" yaseikage yelled, his rage turning to fear as he went to his bleeding bother
"we're twins idiot," tokoyami said as yaseikage hugged him close
"I'm still older" yaseikage joked and sighed in relief
if his brother was able to banter back it meant he wasn't going to die today
both had been close
but they both knew their twin would always protect them
they weren't that old compared to the other gods, they were by far the youngest, so they still had so much to learn
and on their time on earth, training to be hero's on earth
it will only add to their training to become better gods
together, side by side
not as host and quirk
but brothers in arms
and in darkness
