As the days passed, Luna spent her time in the bat cave, mostly sleeping while hanging upside down from the roof. She did not like being woken, however. Robin found this out the hard way. When she wasn't sleeping, she would fly to a distant side of Gotham and return, her white fur stained red. No one was sure what she was feeding off and didn't want to find out.

She often flew over the Batmobile when Batman was out crime fighting. She didn't interfere unless she saw blood and reacted differently depending on whose it was. Sometimes Bruce had to restrain her from killing someone.

He had a code against killing; she seemed to have a code against living.

"Don't let her get too high with you up there, Robin." I watched the bat carefully.

She could tolerate me on her back fine, but I wasn't sure about Robin. Last time she dropped him in a tree.

"I'll be fine. We'll fly ahead so I can get a better view of Joker." Robin said.

Luna flew higher.

Luna would take good care of him. She wouldn't drop him this time. I looked up. The Bat was gone.

She was putting thoughts in my head again.

A dark black horse looked up into the sky. Its rider raised his spear in the air. The sound of horses' hooves echoed around the hills as many purple robed riders followed the White bat above them.

An abandoned toy store. How surprising.

I knew I wouldn't have to do much to find him this time. I heard him giggling above me. He leaped down from his hiding place and I ducked as he swiped a strange looking purple weapon over my head. He was really trying to kill me this time.

"No sign of Joker down there." Robin said. "We should go back and find Batman."

Luna chirped, then shrieked as something flew passed her.

"Woah! What the hell was that thing?" he looked own to see horseback riders wearing purple robes. They were following him and all of them had strange looking purple crossbows.

Luna flapped her wings faster.

"Where did you get the weapon, Joker?"

"Birthday present." He said.

"It's your Birthday?" I already knew what the answer was.

"No." Joker said. "But I'm pretty sure yours is coming up soon. Happy Birthday!"

He swung the scythe like weapon over my head again.

"It's not my Birthday either." I grabbed hold of scythe and yanked it, causing Joker to topple over.

More arrows went flying over their heads.

"You got any ideas?" Robin asked.

Luna grunted.

"Me neither."

An arrow grazed Luna's side. Luna screamed and almost lost her balance.

Joker slowly got up. Batman was standing over him. Behind Batman was a great window overlooking Gotham. Any minute now he would see the great White Bat falling to her death. He grinned at the thought. But something went wrong. His grin faded.

"Joker, what are you doing?" Batman said.

Joker didn't answer. Behind Batman the great white bat appeared. The windows began to crack as she headed straight for them, and then shattered as she crashed through the window. She skidded across the floor on her belly. Robin toppled off her back.

She managed to get up on all fours and shook the pieces of glass out of her fur. She didn't seem too happy. The great White Bat screamed and headed right for Joker.

Batman didn't seem to notice. He just moved towards Robin.

"Tonight Joker shall die." Batman said over the screams of the White bat.

"Batman, do you have any idea what you just said?" Robin said as he pulled himself to his feet.

Batman just stared at Robin, and then frowned. "It can't end like this." He turned to the great bat. "Luna! No! It won't end like this, let him go."

The bat ignored him.

"Luna, you can't kill people. I…" I shooting pain went through his side.

Robin looked up to see a tall man wearing a purple robe. The man put down his crossbow. "Luna!" Robin screamed as he waved his hands above his head.

Luna turned her head to see Batman on the floor, doubled over in pain. She gave a panicked scream and dropped her unconscious 'dinner' on the floor. She picked up Batman with her wing.

Suddenly they were surrounded by men in purple.

"Batman must be eliminated." said the tallest one.

"You leave us alone!" Robin said.

Suddenly a scream was heard. It was not human or bat.

"We were not expecting a Robin and his soul partener." said the man to the left of the tallest one.

"However, he has not met his soul partner yet." said the one to his left.

"Still, we must retreat." said the tallest.

They all disappeared.

Batman was draped over Luna's back.

"That's it girl. You take him to the hospital."

She grunted and flew out the broken window, carrying Joker with her.

I could barely breathe. I managed to pull the arrow out, but there was still a lot of damage.

Luna seemed to know where she was going. She circled around the hospital.

"Forget about me, Luna. Take Joker to Arkham." I managed to say.

She looked back at me, sadness in her eyes. She gave a high pitched whine, then hesitantly changed direction and headed towards the asylum.

"I'll make it. I know you want to get rid of Joker somehow."

After a while, I started feeling the effects of blood loss. I began loosing concentration. The world around me started spinning. I can't remember much of what happened that night. But I do remember my hands slipping from Luna. The next thing I remember is the sensation of falling. I could see Luna circling above me. She quickly dove towards the ground to save me, but it was too late. I had blacked out.
