I noticed some expressed concerns with my version of Batman. Okay, so maybe choosing to fight Supergirl was a bit too much, but in my defense, he was trying to get away. She wasn't gonna let him get away, so he had to fight his way out.

Leave a review after reading, please.

Special thanks to Steve993, Lauriver4ever, and Anna for reviewing the previous chapter.

It was night time at the D.E.O. Supergirl had just returned from her search for Cadmus.

"Anything?" asked Alex.

"Nothing," said Supergirl. "Lillian's smart, I'll give her that."

"Mr. Schott, any luck?" asked J'onn.

"Nadda," said Winn. "I've tried the satellites. I tried security cameras. Nothing."

"I'm guessing the janitor was of no help either," said Supergirl.

"He doesn't know where Lillian Luthor is. He just sold her the Mother Box," said J'onn.

All of a sudden, the power inside the building goes out. No one could see anything. What they did hear was a girly scream.

"Winn, was that you?" asked Supergirl.

"Uh, no," lied Winn.

"Winn," scolded Supergirl.

"Okay, it's me," admitted Winn. "Seriously, who cut the power?"

Supergirl uses her super hearing to listen for an intruder.

"The Batman's here," said Supergirl.

Using her super vision, Supergirl soars through the dark until she arrives where she heard Batman.

"I know you're here," said Supergirl. "You want the alien, you'll have to go through me."

"You want a fight? Not very smart," said Batman, whose voice echoes in the shadows.

"Uh, you started that first fight," argued Supergirl.

"Because I know you would never let me leave. Reminds me of my first encounter with your cousin," said Batman.

"Well, you may have kicked his butt, but you're not gonna kick mine... well... again," said Supergirl. "By the way, how did you even know the alien was here?"

The Dark Knight didn't say a word. Supergirl tried using her super hearing, but she didn't hear anything. Suddenly, a light shined in her eye. She flies towards the light at high speed, only to end up tackling someone to a wall. It was Winn.

"Whoa! Whoa! Hey! Hey! I come in peace," said Winn, surprised by the attack.

"Sorry, Winn," apologized Supergirl, letting go of Winn.

As it turns out, the light came from Winn's phone, which had a flashlight on it.

"We have agents guarding the alien," said Alex. "Did you find him?"

"No," said Supergirl. "Even with my super hearing and super vision, I can't find him."

"He certainly learned a lot from facing Superman," said Winn. "Gotta give him props for that."

Winn continued shining his phone's light everywhere. He suddenly found someone dressed in black on the roof.

"Guys!" he yelled.

Winn points at the ceiling. When everyone looked, there was no one in the light.

"He was there just a second ago," said Winn.

Suddenly, a bat-shaped projectile knocks the phone off Winn's hand, causing him to scream again.

"I just bought that phone," said Winn.

Supergirl uses her super hearing again. All she could hear was footsteps on the ground, but nothing on the walls or ceiling.

"This guy is really good," said Supergirl.

"Almost twenty years of experience helps," said Alex.

"Hey!" shouted Supergirl. "You don't need the alien. We know what you're looking for, and I can help you find it. We can help you find it."

No one responded.

"J'onn, can't you, like, read his mind or something?" asked Supergirl.

"I tried," said J'onn. "M'gann did as well. I guess our intruder found a way around that."

Supergirl continued searching the entire building for Batman. So far, she can't see or hear him. A part of her can't help but feel impressed. She's a Kryptonian, which means she has a lot of power, and yet, a man dressed in a bat suit constantly evades her.

Alex returns. She fires a flare at the ceiling. The flare lights up the entire room. Supergirl can see Batman at the corner of the ceiling. She flies towards him, but he detonates a smoke bomb, which allows him to evade her once again.

Batman lands on the floor. Several agents aimed their guns at him.

"Wait!"

Supergirl descends in between the agents and Batman.

"He's mine," she said.

"What happened to helping him?" asked Winn.

Supergirl faces Batman.

"You really want to do this again?" asked Batman.

"Hey, you're the one who doesn't want to talk," said Supergirl.

"I don't need your help," said Batman.

"Well, then in that case..."

In the blink of an eye, Supergirl grabs Batman and tosses him to a wall on the other side of the room. Batman gets back on his feet. Supergirl zooms towards him, grabs him again, and then slams him to the ceiling before gently letting him down.

"You ready to talk yet?" asked Supergirl.

Batman pulls out a little device and pushes the red button. Suddenly, Supergirl started covering her ears in pain as she collapses to the ground. Alex takes out her gun and fires. Batman dodges the blast. He detonates yet another smoke bomb and disappears.

"Find him!"

Alex comforts her sister.

"Are you okay?" asked Alex.

"Well, my ears are starting to bleed," said Supergirl, digging blood out of her ears. "He's on the roof."

Supergirl heads to the roof of the D.E.O. and finds Batman just standing in the middle.

"Why are you still here?" asked Supergirl.

"Let's just say I had second thoughts," said Batman.

"I heard another voice," said Supergirl. "You're talking to someone. Comm-link?"

"You said you wanted to help," said Batman. "What do you got?"

Supergirl lands on the roof. "You heard of Lillian Luthor? She's the one who that alien sold the Mother Box to. We've been trying to find her, but so far, we're not getting lucky."

"Thanks for the tip," said Batman.

Batman turns around and was about to jump off the roof.

"Wait!" called Supergirl. "That's it? You're just gonna go back working solo after you get the info you need?"

"I work better alone," said Batman.

"But, Master Bruce, you could use the assistance," said someone in the comm-link.

"Bruce?" asked Supergirl. "Wait? Bruce Wayne?"

Batman taps his comm-link and says, "She can hear you, Alfred."

"Oops. My bad," said Alfred. "Well, she is Superman's cousin. I suppose there is no harm in her knowing."

Batman turns around and faces the Girl of Steel. He turns off his voice modulator and takes off his cowl, revealing his face.

"So, what do you propose, Ms. Danvers?" asked Bruce.

"Wait, you know who I am?" asked a surprised Supergirl.

"The glasses don't really work," said Bruce. "Again, what do you propose?"

"We work together," said Supergirl. "But first, I want to know. Why do you need the Mother Box?"

"To lock it up for good. Make sure no one ever uses it," said Bruce.

"Then we both want the same thing," said Supergirl.

"Hate to inform you, Ms. Danvers, but I'm not a particularly trusting person," said Bruce. "Like I said, I work better alone."

"If you want to work alone, fine, but at least stay in contact," said Supergirl. "Cadmus is too dangerous for one man to handle."

"Just keep your cousin out of this," said Bruce. "I don't need two Kryptonians to keep an eye on."

"I'm beginning to see the 'not trusting' part," said Supergirl. "So... partners?"

Supergirl extends her hand forward. Batman looks at her hand and then at the Girl of Steel. Reluctantly, he shakes her hand.

"This is not a partnership, but I am accepting your assistance," said Bruce.

"Can I trust you with my secret?" asked Supergirl.

"As long as I can trust you with mine," said Bruce.

Bruce puts his cowl back on and jumps off the roof. Supergirl looks down and sees him gliding in the air with his "wings" spread out.

"For someone who can't fly, that's actually pretty cool," said Supergirl.

It may not be the rematch you were expecting, but I had other plans. One of them is trying to fix Batman's character, especially after the concerns expressed in the reviews.
