DISCLAIMER: I own nothing except for the small parts of the plot that I make up.
Okay, everyone knows that the heart of the Voltron lions are rocks, right? If not, you do now! Anyways.
One day while running tests on the lions, the original paladins watched as small parts of the lions' hearts broke of and combined to form one (f/c) rock. King Alfor tried to combine the rock with Altean technology, but every time the tech would blow up.
When Zarkon tried to take the lions by force, Alfor sent the rock with the Blue Lion to Earth. Nine-thousand-nine-hundred-and-eighty-two years later, the rock leaves the lion and goes to a baby in a local hospital. The rock melts itself and goes into the baby's bloodstream. That baby turns out to be you.
Eighteen years later :
(Y/n) is sitting in the peaceful night, enjoying the night air when she hears an explosion. (y/n) goes to investigate and finds three boys and a girl trying to carry her cousin out of a small lab surrounding an alien space ship.
"Shiro?" she asks.
