Book 1:
Scene 1:
Harry let out a deep breath as he sat in his room, holding the potion in his hand as he reflected on his last few years at Hogwarts. The school had been a welcome break from the horror of the Dursley family. Even though he still held a grudge the size of Russia against the headmaster for putting him there in the first place. Still, it wasn't all bad as he had at least learnt some things from there. Mostly how to pick locks and steal food so he wouldn't starve, but still...learning is learning.
Once he came to Hogwarts, he realised that he was apparently a world-famous celebrity. His parents had died trying to protect him from an evil wizard that baby Harry had somehow defeated. Everyone expected him to go into Gryffindor's house like his parents, but he hadn't found the house to be appealing as the people there looked irritatingly loud and friendly, something that had also ruled out Hufflepuff. Slytherin was also out as he hadn't fancied spending his school years in a house with the likes of Malfoy and other such similar beings who would wish him harm, leaving him in Ravenclaw. Something that had shocked the whole school.
In Ravenclaw, he had actually made a few friends, something that he hadn't thought was possible. He had enjoyed his first year, for the most part, learning new magic and exploring the magical world had been quite an adventure. But the world soon lost its magic as he found himself in constant danger. He had nearly died in his first year and his second thanks to the remains of Voldemort, while his third year had him deal with the fallout of his innocent godfather and a disguised death eater, now he was in a tournament with a high death rate because the bloody headmaster couldn't think of anything better to protect the goblet than an age line.
Since his first year, he had made it his mission to learn the best he could, which was why he was now in his room doing something risky and very stupid.
"Bottoms up," He said before drinking the potion, ignoring the rather horrid taste. What followed was a rather intense and painful experience, but by the end of it, he had achieved the exact results he wanted.
At night, all of the occupants of Hogwarts School of Witchcraft and Wizardry fell asleep in their beds, all apart from one being who slept upside down from the frame of his window. A green-eyed, lightning-bolt-scarred bat.
Book 2:
Scene 2:
"Master Harold?" Alfred Pennyworth, the Wayne family butler, called as he entered what he mentally dubbed as 'the Bat-Cave'.
Master Harold was a rather complicated person, even as a child. He had rarely smiled ever since his parents were murdered in cold blood in front of him, nor had he been much of a normal child before the horrid event. He had always been far too mature for his age, he looked at everything analytically, even people. He often looked like he was considering the best way to take them down.
After the deaths of his parents, he had been constantly studying everything he could from sociology to forensics to chemistry and every other subject he could get his hands on. At least until he had reached his twenties, then he had left the country for five years, only returning a month ago. Shortly after his return, he had stumbled upon a cave underneath the manor and from then it had been a challenge to keep him out of the blasted place for more than half a day.
"Master Harold?" Alfred called once more before freezing as he finally spotted the young man in question.
Hundreds of bats seemed to fly around him in a circle as he floated several meters in the air with a rarely seen smile on his face, wearing what looked like full body armour and a cape. Then to Alfred's horror, Master Harold turned into a bat as well.
Book 3:
Scene 3:
Superman flew down to the rooftop where he saw Batman waiting for him, the caped crusader was dressed head to toe in armour, a bat symbol on his chest. His head wore an armour mask that covered his whole face and had two bat-like ears that looked a lot like horns.
"You called?" Superman asked.
"Oliver stumbled upon a stache of krptonite," Batman said. "We suspect Luthor is up to something,"
"Let's deal with it," Superman sighed. "And hopefully quickly, I've got a date with Lois. Hey, perhaps you and Diana can join us for a double date?"
"No," He said bluntly and quickly.
