Lewis Wayne

Superbat creation. She was basically created like Conner was if you can't be bothered to read her bio down below XD And sorry if her Bio doesn't make sense I'm half asleep right now

Lewis Wayne: 
Created by the Anatorian's from the DNA of Superman and Batman, because they needed a hero to protect them from the Venror's Underground dwellers of Anatoris (the Anatorian's home planet). 
Through there travels of the universe they heard stories of earths mightiest heros, especially those of Superman. A man who could fly, was bullet proof, could shoot lazers from his eyes and much more, they thought this was what they needed they're hero to be. But then they heard about Batman, a man that could vanish in the blink of an eye, a man that could destroy even the feared villain Doomsday. They thought long and hard and looked at the other heros too. But in the end they decided that they wanted their hero to be like both of these and have both of these mens powers (yes they thought that batman really had the power to vanish into thin air XD).
They sent robots to go after the justice league and once they had taken samples of there DNA, they returned.
After creating Lewis in the lap they brought her up like a normal child, teaching her simple things like math, science and the human languages was not a problem (as they had coded into her dna to be able to learn faster than most humans).
As soon they were done teaching her the basic they tried to teach her how to use her powers but soon discovered she couldn't use them on there planet. 
Disappointed they flew her to earth where they put a sign over her head saying 'Congratulations its a girl', and dumped her on Bruces door step (There robots hacked into the watch towers computers whilst they were getting DNA from Bruce and Clark, so that how they know Bruce is Batman) 
Bruce was shocked at first trying to figure out who her mother could be. 
She lived happily with him on earth sulking every now again; when she couldn't go out with him even though big bro Damian could. Until 6 months after she had been there when she started using her powers (by sneezing and accidentally making herself fly backwards into a wall) 
Then when she started using heat vision Bruce took her blood finding out that she was part his and part Bruce's.
So now she spends some nights with him and some nights at Clark's with Louis, learning how to use her powers.
