Aurora made the first move. Using her telepathy, she tried to break through Achilles' mental barriers. Achilles countered trying to force her out of his mind and both were knocked off balance as a telekinetic force expanded before them. Aurora tried again and this time Achilles countered even more forcefully, the resulting shockwave knocking them backwards. She knew that the attack wouldn't work but she needed to catch him off guard if her plan would succeed.

Switching tactics, she flew at him and landed a punch at his jaw sending him flying backwards. Achilles smashed into a rock and came to a stop. He got up and tried to return the favor but his punch was blocked. He swung with his left but Aurora ducked and punched him in the stomach before she punched him again in the face.

Achilles staggered backwards but quickly regained his composure. He aimed a punch at her face that she blocked easily but he used his Martian abilities to morph another hand and punched her in the ribs. He punched her again in the face before he lifted her up and slammed her into the ground.

Aurora slammed into the ground and quickly rolled off to the side as Achilles' found the space where she had been a few seconds ago. She stood up in time to block another punch but Achilles kicked her in the stomach. Her hand clutched her stomach as pain shot through her body. She saw Achilles aim another punch to the face but she caught his fist and ducked under his hand and turned her back towards him before she brought his elbow on her shoulder and pushed down hard and elbowed him in the back with her other hand.

Achilles barely flinched as she broke the joint but before he could counter she grabbed hold of his neck from behind and used her strength to lift him over her shoulder before she kicked him in the stomach and sent him into the ground. Achilles got to his knees and looked at his injured hand. He watched as it healed before his eyes and tried out the joint to make sure it was working properly. Once he made sure it was fully healed, he got to his feet and flew towards his sister. Aurora waited for him to throw another punch but he tackled into her and sent them flying before he slammed her into the wall of Luthor's mansion. He then proceeded to assault her with a torrent of punches to her torso and face.

Aurora tried to block the punches but Achilles was using his morphing abilities, growing new arms and reabsorbing them at random. She blocked a few of them but most of them found their mark. Achilles decided to throw one last punch putting his telekinetic energy behind it. The force of the energy together with his strength caused her to go through half the walls in the mansion before she came to a stop in one of the studies and the room, already weakened by Achilles' violent arrival, caved in on her.

Achilles flew towards her and hovered a few inches of the ground. He moved closer towards the ruble and used his telepathy to find out her status. Unfortunately since both their minds were currently closed to the other he couldn't tell how much damage he had caused. However, using his hearing he could hear her heartbeat as well as her breathing. "You're holding back." He said knowing that she could still hear him. "I thought you wanted to stop me dear sister. But maybe you don't have it in you or maybe you don't love me enough to take me down." He was taunting her, knowing that if she became mad enough she would stop holding back. "You know, father didn't hesitate. He loved me enough that he defeated me as fast as he could. But we both now that you are nothing like father."

Aurora hearing those words knew that this was her opportunity and she reacted, explosively. With a scream of rage a telekinetic blast threw away the rock and debris covering her and Achilles had to lift a telekinetic shield to protect himself from the missiles. Still, the force from the blast sent him a few feet back. After the dust settled, there stood Aurora, but she had changed and only those who knew her could see the subtle differences. Her eyes were glowing blue and there was a shift in the way she held herself, as if she could tear anything that got in her way to shreds. But the one thing that changed the most was her smile. It was the smile of a predator that had cornered its prey and Achilles knew that he stood no chance against her in this state.

Achilles rushed forward and punched her in the face. His fist made contact but she barely moved and sudden pain erupted in his knuckles. He was used to pain and he punched her again with the same results, Aurora having increased her density she was now much more invulnerable than before. Having not yet mastered density shifting, he threw another punch but Aurora caught it easily and squeezed until she felt the bones shatter in her hand. She looked at him in the eyes and he gave her a smile, "Well it's about time."

"Batman, we have managed to receive satellite footage of Luthor's island from the coordinates you gave us." Mal reported typing away on the computers.

"Patch it through to the bioship as well." Batman said as he, Canary and Zoe came closer to the monitors. "They need to know what they are walking into."

Mal typed on the keyboard before he notified the team, "Nightwing, incoming satellite video of the island." He opened another window while leaving the channel open so they could here each other. "Well it seems Achilles got what he wanted." He commented as they watched Achilles slam Aurora into the ground.

"I thought you said he wasn't good at hand to hand." Robin's voice floated through the comm. Channel and Batman, Canary and Mal turned to Zoe.

"Compared to us, he isn't." Lilly's voice replied.

"He has no chance against her but she must be holding back for some reason." Zoe added her voice strained as she watched Achilles pummel Aurora to a pulp. She knew she didn't have anything to worry about but that didn't mean she was comfortable watching her girlfriend get beat up.

"Well it seems that he is better than you thought." Rocket said as she watched the girl get buried under a pile of rubble. "We should go help her."

"Miss Martian, what's our ETA?" Nightwing asked.

"About fifteen minutes but I don't think she'll need our help." M'gann answered and they all turned to the screen to find Aurora shrugging off Achilles' punches.

"Now you get to see the second best fighter of our team in action." Lilly said her attention on the monitor. The team did the same and they watched as Aurora turned the tables on her brother.

At the cave, Batman, Canary and Mal watched in awe as Aurora fought with a grace they had never seen before. Every punch Achilles threw was either blocked or dodged but all of Aurora's blows found their mark. She weaved and danced around her opponent every blow delivering as much damage as possible and the results could already be seen. Achilles' movements were getting sluggish but Aurora didn't seem to be stopping her attack anytime soon.

"She's amazing, isn't she?" Zoe said her voice carrying a hint of pride.

"Yes she is. But if she doesn't stop soon she might kill him." Canary stated looking concerned.

"Don't worry, they are more resilient than they seem." Zoe gave a final glance at the monitor before she turned and walked away from the computer.

"Where are you going?" Batman asked turning to face his future granddaughter.

"I need to check on the prisoners." Zoe answered without so much as a backward glance.

Achilles looked at his sister as she stood above him and her bracelets turned into a pair of bladed tonfa. Wiping some blood from his chin Achilles barely had time to react as the blades sliced through the air and tried to get to his feet but a punch from Aurora sent him flying backwards. He fell to the ground and Aurora jumped at him her arm outstretched the blade aimed for his neck. Achilles brought his hand up his bracelet protecting him against his sister's attack. He formed his sword and used it to fend Aurora off. "I know you are mad sister but do you really want to kill me?"

Aurora remained silent and attacked swinging the bladed weapons at Achilles who blocked them all. Seeing an opening, she slashed his arm and kicked him in the gut sending him into the sand a few feet from her. "Now who's holding back brother? You're supposed to be the best with a sword or maybe all those years in the Fortress have made you soft."

Achilles was uneasy, this was supposed to go differently but Aurora's emotional state had complicated things. He needed to end things before they got out of hand. He ran at his sister and thrust the blade towards her chest. It was a weak move and someone as trained as Aurora could have blocked it and overpowered him but that's not what happened.

Instead of blocking or moving out of the way, Aurora grabbed his hand and plunged the sword into her chest before punching him square in the jaw. Achilles hit the ground and stared in disbelief at the sword protruding from his sister's chest. Aurora fell on her knees and Achilles rushed to her side, grabbing her before she fell. "Got you." She whispered before their eyes glowed red and a telekinetic wave flattened everything on the island and engulfed them in dust.
