Chapter 6

Declan went straight home after leaving school. She did send the message in order to warn them. If they were warned they'd be at their best and she didn't want them to be at their worst. She had some morals that she thought it was low to just attack them. She really didn't want to, but she knew that she couldn't talk to the ones that could help her unless they were out of the way. Declan then dressed in flexible clothing and prepared to leave.

Within the hour of getting the message the bionics were in their mission suits and station in their respective areas. However, that was about three hours ago and it was around seven.

"Adam, anything outside?" Donald asked the oldest through the com.

"No, I'm bored…" Adam complained.

"I can help with that," a voice said coming to halt in front of him. She then used her molecularkinesis to crush the earpiece.

"Adam!" Multiple voices cried out that never reached the teen.

"Mr. Davenport!" Bree shouted to the man she saw as her father.

"Stay put Bree," he instructed. She nodded even though he couldn't see her. Adam could handle himself.

Adam couldn't believe how strong she was. HE also thought about telling Chase I told you so, but that was for another time. Adam fired off his heat vision at her. Declan simply put up a force field to deflect it. However, what she did with it afterward was different than what he had seen Chase do. She launched it as a wave at him. He powered up his blast wave ability and launched colliding with her. The abilities collided and made an explosion of energy waves. Adam was knocked onto his back. He quickly got up and realized Declan was gone. He thought he scared her off.

"Impressive, I don't have that one." He heard behind him. He turned to see Declan smirking. "But I have some none of you do."

She then launched her hand at him where electricity came out. Adam went flying and landed against the wall before sliding down into a bush.

Bree could hear the noises from the fight outside. She paced back and forth and at one point the house shook from the energy given off in the blast. It took every part of her not to super speed out there and help her older brother. Whoever it was couldn't be that strong? Adam was muscle and even if she took him down hustle would finish her up quickly.

"Bree I did it!" Adam voiced came from outside. Bree smiled and ran to the door to meet her brother and find out who was behind it.

"I knew you…could…" Bree said slowing down as Declan super speeded in front of her.

"Fooled you, didn't I?" Declan said to her. Bree just kept looking at her; it couldn't be.

"What did you do to Adam?" Bree asked concerned for her brother.

"He'll be fine," Declan waved her off. "Just taking a nap in a bush."

"Rah!" Bree screamed and super speeded to attack her. Declan then used both her super speed and strength to push Bree. She feel back onto the couch. Declan then grabbed her and tossed her up. Bree caught herself on the ceiling and launched back at her. Declan put up her force field and Bree simply bounced off. She landed on the floor and regained herself. Bree ran at her and the two engaged in close combat using their super strength to power their attacks. Declan at one point grabbed Bree's arm and tossed her before she Geo-Leaped. Bree gritted her teeth and prepared herself. She felt a tap on her shoulder before a shock.

As the older sibling were to take care of D the smarter Davenports worked on a way to 'shut her down'. Chase seemed reluctant at first, but when hearing Adam was taken down quickly began to help out. During one of the fights from the basement they felt the ground shake and mentioned it was like war. Donald glared at Douglas who completely ignored him. Besides trying to come up with a genius device to render her useless, he was trying to think about what he knew of her. Some information came back, but not what needed to help win. The next they knew Bree's transmission cut out. They all looked at each in concern.

"Don't worry Mr. Davenport, we defeated her," Bree's voice came from the hallway.

"Really?!" he said. He didn't think they could beat her, but they did! He ran toward the voice and then the remaining two saw him fly by. He landed on the floor and grunted.

"Mr. Davenport!" Chase cried running to his side to help him.

"I think so…" he answered him taking his hand.

"That's sweet…" a voice sneered.

Douglas heard the voice and tried to go out the other way, but barrels moved in his way and they were trapped. He turned to look the same time Chase. He couldn't believe who was looking at. Neither of them could. Chase was dumbfounded. He defended her and here she was. Everyone was right. Declan was D. Davenport which he wondered about.

"Declan…Why?"

"Why not? Why would I? I spent most of what I remember of my life in a cell because of him!" Declan shouted pointing to Douglas. "I glitch too much and needed something stable. I know why I glitch, it's because I'm not engineered to have bionics, but I have them anyway! He messed up when implanting me and now all I feel if pain."

By this point it looked like she was going to cry. Chase looked back at Douglas wondering if she was lying or telling the truth.

"Is it true?" Chase asked.

"Yes, but I wanted you back…"

"And you took a girl off the streets to do it!" Declan snapped.

Douglas shook his head. She didn't know the whole story. She only knew what she remembered after he saved her life.

"I did it to save you life," he said. Declan face slowly relaxed as she listened. "I found you in a park one night after I was kicked out of Davenport Industries. You badly injured and very ill. I couldn't leave you there or call anyone. No one could have saved you and I knew I could. So I implanted bionics that were to save you. What I didn't expect was all the glitching. I felt helpless and I couldn't fix you so I pretended to be Donny and said you were an experiment gone wrong."

"You were going to leave me there!" she screamed. He was taken back a minute at her by her roughness.

"Yes…" he admitted. He didn't want to lie to her again. "You said you were in pain."

"My chip…something's wrong. I get headaches and I feel something is trying to take over making me want to do what I don't want to. I didn't want to, but I feel it pushing me," Declan explained. "I tried to look at it myself, but I can't."

Douglas slowly walked toward the girl. He was being cautious. He saw what she did to Donald and that would be a light toss in what she'd do to him. She'd probably kill him she felt like it. He remembered a lot about her from seeing her. He had also loaded her up with more than enough abilities to defend herself. The vengeful side of him at the time wanted her to take down the siblings. He even had a Triton App and everything…that must be what happened. He remembered when she was testing Electrokinesis back when she electrocuted herself. It caused all the glitching. He touched her upper arm to show he was caring enough to help her, but she reacted to his touch. Her body went stiff and stood straight up. Douglas looked into her eyes to see them spiraling green from their normal brown.

"Suicide App Activated." Declan said in a monotone. "Directive, destroy Douglas Davenport."

She then used her molecularkinesis to lift him off the floor. Her hand began to slowly close and the Douglas felt like it was around his throat.

AN: And we have chapter 6! So you know some, if not all the backstory, behind Declan. She technically adopted. With due time, if not the next chapter, you will find out about the Suicide App. So please let me know what you think in a Review as I want to hear from you!
