Origin Story
I wasn't always with the good guys. My parents were evil scientists who helped Music Meister and Joker with their evil schemes. It was forced on them, because they're family. So I was that child that helped Joker distract Batman, and Music's Meister's l'il' assistant with my voice. Unfortunately, I had my uncle's power to hypnotize people and animals with my voice. I usually told Batman about their evil schemes, but... he ignores it most of the time. One day, after the major "Music Meister Musical" fiasco, Batman came to me on my seventh birthday when I was wandering around and asked if I wanted to be his student for crime fighting. It was a dream come true! I knew that being good was my destiny.
Seven Years Later...
"HIIYAHHH! Think you're so tough?! Well, you're not!" I shouted while I was sparring with Robin and Aqua lad.
"Midnight, You should really be silent when you are fighting crime," Robin corrected. I had made myself a quiet hero, slow to speak, quick to fight and hypnotize, always silent when hand to hand fighting.
"Ya, but you know how I have to shake things up a bit. I'm tired of being so silent. I'm not that scared little girl anymore. I'm fourteen," I replied.
"So? You gotta stay with what you made yourself," answered Aqua lad as we slowed down the sparring to a stop. "You have to be true to your character. You can't just be loud making sassy remarks to your opponent. You're the quiet type."
*sigh* They listen to The Justice League "Guess you're right. It's just, when I am at a place filled with kids my age, I stay quiet. It becomes hard to talk to anybody, even close friends," I said, trying to justify my earlier outburst.
"Robin, Midnight Music, time to go. Gotham's in trouble," commanded Batman. When did he get here? I thought. Oh-well. Have to think about it later.
As we came into the bank, we saw Two-Face and his ugly group blow up the vault. I glanced at their ears to see if my voice will work on them. Nope, they had earplugs in to block out my singing. Fortunately, it made them rather clumsy, because they couldn't hear Two-Face's commands. "No you idiots! This vault! It has the money!" yelled Two-Face. I decided to jump to the chase and started taking them out.
"Midnight! What are you doing? You're supposed to wait for my signal!" cried Batman. I didn't care. I took out about half of them when Batman and Robin joined the fight. When Two-Face and his henchmen were defeated I got the scolding of a lifetime. "Midnight! What were you thinking? If Two-Faced had managed to escape, we would be busy trying to track him down when we could have been helping in other parts of the city. What is going on today, huh? You usually wait until I say so," scolded Batman.
"Bats, she has been acting strange. When we were sparring, she yelled when she normally doesn't. Then she basically said she wanted to be more talkative and stuff," explained Robin.
"Look, today I'm just a little tired of my usual, quiet routine. Got a problem with it?" I asked.
"Just listen from now on. Go home. I'll use my communicator if we need you," said Batman.
"Fine," I answered, knowing better to not argue. I went to my little hide-out in an abandoned warehouse across town that no one knows I have, not even Batman.
