Steampunk: Heartbreak.

Andrew Valdez is a regular boy who is, while in this case, was a top student at the prestigious boarding school that he used to go to. Nowadays, he is mainly roaming the streets of Gotham City, alone.
He is plagued with nightmares and PTSD after seeing his parents die at the hands of Joker and his little bitch, Harley Quinn.
He is admitted into an asylum four months later to treat him for those reasons, yet nothing seemed to work until he met Dick, the son of Bruce Wayne.
Immediately, his health started to get better with each day they spent together.
Unfortunately, Joker sabotaged their next meeting and left a clue that only Andrew knew so the young justice and Batman had to trust him.
Little did they know that he was the son of Leo and Calypso Valdez, a demigod and former sorceress, therefore he had god heritage and titan heritage running through his veins. When Percy (fem ver) found out, she got very pissed.
The clock was ticking towards an untimely death for Dick unless Andrew can stop the death of his one and only friend from occurring in the first place.
Can Bruce and Percy trust the steampunk or will Dick die?

I do not own Justice , Young Justice, or Percy Jackson, I only own the plot and the characters that aren't in any of the three that are listed.
It's just a fanfiction
