Celestroid Fusion

Rainbow rode down the Sector 5 elevator and enter the Navigation Room and contact Luna once again.

"Luna, I'm in Sector 5." Rainbow said.

"I'm afraid it's gotten much worse. The damage seems to have been caused by a creature kept here by the researchers, who named it… the Nightmare." Luna said and stop.

Rainbow knew what she was thinking.

"Hey, it not Nightmare Moon. We put a end to her for a long time. Besides, there no way the X-Parasites could have got Nightmare Moon DNA because it still...well, you know." Rainbow said not wanting to hurt Luna feels.

"Thank you Rainbow Dash. Accord to the reports, Apparently, it was a bio-mechanical organism designed for military applications… It possesses uncommon power and can manipulate gravity. I must assume that it has recently become an X-host. We have no choice. You must find it and defeat it. I can't confirm its location; it's out of control. Hurry before it destroys the entire station… Hurry Rainbow." Luna said and the connation was cut as a ear-pitch noise was heard.

Rainbow helmet block out most of the sound but she still try to cover her ears.

"Man! If I didn't have my helmet on, my ears would have bleed to that noise." Rainbow said to herself and ran out of the room.

Rainbow walk though the yellow hatch and stop in surprise at the sight of the room. Broken glass from what was likely the Nightmare's containment area littered the floor, steel beams had been bent and torn, some of them balanced or littering the upper areas of the foyer, and long cracks were running across the parts of the glass that hadn't been broken yet. It's clear that the researchers didn't just name it 'Nightmare' for effect; its power was real.

"Oh, man! If that get on Equestria, then we'll all be in big trouble. I got to find it before it too late!" Rainbow said and ran though the damage room.

Rainbow ran through the damage room and check everywhere for signs of the 'Nightmare'. She was able to find an Missile and Power Bomb packs, before seeing an destroy hatch.

Rainbow ran through the destroy room taking out X-Parasites as she did and blast though a crack floor to see that the place was flooded.

Wait, this is one of the ice rooms. That water must have come from the ice that melt. Agh! I have to go in there don't I? 'phew' guess I have no choice. Rainbow though and jump in.

Rainbow was able to breath thanks to her suit, but the water made her slow and she couldn't her Speed Boost to get pass. Plus the forms that the Parasites took was also slower but she couldn't dodge their attacks that well. After walk under water and finding as much Missile Tanks she can, she climb out of the water and saw the Red Eye guard. She waited until to real eye show and fire a missile at it. She was able to spot a E-Tank but knew some was off. Rainbow place a Power Bomb on the ground and saw a hole above the path way and a weak floor half way to the E-Tank. She took the upper path, grab the E-Tank and roll onto the weak floor and fell though it.

Rainbow drop into a room that was fill with a whole brunch of things she doesn't know. But she call the room Junk Room because most of the stuff was beyond repair. Then the room started to shake and Rainbow saw something that appeared to be similar to a ghost began rising out of the floor, seeming to be wailing all the while. And once its body was fully in the room, it materialized, revealing itself to be the Nightmare.

Almost as it soon as it formed, the misshaped creature began to hover around and fire lasers from its arms. Rainbow use her Space Jump to get over these shots, the Nightmare following her up but keeping its distance. As she dropped down, Rainbow noticed a red flashing spot on its lower body. After landing, she ran underneath it and fired two missiles straight up, hitting the engine and causing the creature to let out a type of shout. Rainbow repeated the process of going up and getting under it, scoring a few more hits, but then it seemed like she made it mad.

"What wrong? You don't like it...EGH!" Rainbow started to said before she felt heavier.

The Nightmare's engine began to rotate quickly and the whole room seemed to ripple. When Rainbow tried to move, she felt that her hooves felt much heavier and she could no longer use her Space Jump. She saw the beast rise up high enough and shot an Ice Missile at it, only to watch it fall back to the ground slowly and explode.

"Horse Apples! I can barely move, let along use my missiles. Guess I should try my Plasma Beam." Rainbow said and charge it.

Rainbow fire at the engine and heard the Nightmare wail as the pain hit it.

"Oh Yeah! You can stop my jumps and my Missiles, but you can't stop my Plasma Beam." Rainbow taunted it and fire again.

Each hit caused the engine to work faster, possibly to compensate for the damage she was causing it, and green slime began to ooze out of the eyeholes on Nightmare's mask like tears.

'Ew... There's something nasty under that mask, I can already tell.' Rainbow thought as she did her best to jump over the attacks that the Nightmare send to her.

After fight for what felt like hours because of the extra weight, the engine stopped flashing red and the ripples in the room began to vanish. In a second, Rainbow felt herself go back to normal weight and leapt onto the nearby ladder on the wall, turning to look at Nightmare. It floated in place for a moment before it gave off what sounded like an angry roar as its mask broke, revealing its true face.

"Well, I was right about what was under there, but I didn't expect it to be that gross..." Rainbow muttered to herself.

She knew Rarity would faint at the sight of the Nightmare true face and have nightmares about it for the rest of her life. Still she fire her Missile at it as the Nightmare started to fly closer. Each hit made it look even more disgusting, as its face looked like it was going to fall off the more damage it took.

Ok, I am so not telling Rarity about this thing. It get even more gross as I attack it! Rainbow though as she drop from the ladder as it got to close.

After dodging and shooting missiles for a few more minutes, The Nightmare's arms fell off and then into a Core-X. Like before Rainbow fire her Missiles at it and after six Missiles the shell broke and Rainbow grab the X. Her suit once more gave her an up date.

"Gravity Suit effect recovered. Can now move freely in water." It said.

Like with the Varia Suit, a bright light cover the area and when it fade Rainbow saw her suit change again. The green-yellow fur coat turn into a light purple almost like Twilight's. And the dark purple on her turn into her normal fur color, cyan.

Rainbow left the room and was able to give that Gravity Suit a test. Once she step in water, she felt that she was still on dry land and was able to move quicker as well. She turn to head back to the Navigation Room, but fond the way was block. Using the Gravity Suit, she use the Speed Boost to break a wall behind a hatch she saw earlier and soon fond herself back in Sector 4.

Luna was getting worry that if the Nightmare isn't stop, the whole station was going to be gone. But she had fate in Rainbow Dash. She was quiet surprise that she got a Plasma Beam before Work Tool send it. But she did tell him that he can use it for other studies.

Work Tool on the other hand finish a new upgrade to Rainbow missiles. He knew it will be very helpful. He had to wait for Luna order but knew she needs to be alone right now. Not even Celestia went near her. Still, Work Tool knew that Luna will what to help Rainbow and so did he. He turn his own screen and send them to the Station.

"I'm sorry Luna, but Rainbow really needs those." He whisper.

The he look up and look around for his brother Scanner.

"Hey, has any pony seen Scanner?" He ask out loud.

"He said something about getting back to studies and head off for his lab." One pony answer.

His lab? Must be about the X-Parasites again. Work Tool thought.

Still he didn't trust his brother. After checking to make sure the Data was send, he walk over to Celestia to tell her what he thinks his brother up to.

Rainbow move though out the water rooms and took out any X-parasite that stood in her way. Thanks to the Gravity Suit Rainbow was able to move though with ease. She fond a few Missile and Power Bomb packs until she fond herself in the Security Room. Rainbow knew that she wasn't told to unlock the hatches but knew there was no way of getting though unless she does. She unlock the level lock and left the Room. She travel thought a few more water room picking up more Power Bomb and an E-Tank.

After using the Speed Boost, Rainbow found herself back in back in familiar rooms as well as rooms she hasn't been in because the level hatches were still lock. After using the Shinespark to shoot herself upwards and hit a ceiling part that was breakable by the Shinespark, she grab a ladder and fire an Missile. The ceiling broke and Rainbow climb though.

She enter a room that was fill with X-Parasites taking shape for the spike creatures she seen though out the Station. Using a Power Bomb, she clear the room and enter the familiar area she knew. She drop down and enter thought a red hatch and fond herself in the Data Room. She was surprise that there was an weapon upgrade waiting for her.

"That odd, An weapon upgrade without me knowing? Well if it useful I better grab it." Rainbow said and step into the machine.

Her suit glow and it gave her an update.

"Diffusion added to Missiles. Charge the Missiles and fire to release a steam for ice from each missile." it said.

Rainbow left the room and gave the Diffusion Missiles a try. She charge it up and fire. She watch as four giant snowflakes appear after the missile hit the wall, freezing a form Parasites. Before heading back to the Navigation Room, Rainbow make some quick pickups for two Missiles pack and a Power Bomb pack. She went back and enter the Recharge Room and refill herself before entering the Navigation Room and contact Luna.

"Luna, I here. Got a little lost, but I got this really upgrade for my missiles." Rainbow said.

"You upgraded your missiles? That's unusual... I didn't order any upgrade to be send to you. A procedural error, I'm sure..." Luna said.

"Huh?" Rainbow ask.

"Even so, I did not approve of bypassing security level 4. From now on you will use more discretion." Luna said.

"Hey! I open the locks so I can get out of Sector 4 water depths! If I didn't then I won't be here right now!" Rainbow yell explaining why she did.

"Rainbow...You just raise your voice at me." Luna voice came back really surprise.

Rainbow stop herself. She lost her cool and yell at one of the Princesses. That was something nopony does and doing so can get them in a lot of trouble.

"I'm sorry Luna." She said.

"No, It fine. You told me your reason, so I'll let it slide. In any case... Rainbow, do you remember the Security Robot you faced back in Sector 3? I believe the X have infected is to say, they have claimed the organic components that form its neural network. It has entered Sector 6 (NOC). I don't know what it's planning, but let's not wait to find out. You know what to do, Rainbow. To Sector 6, quickly." Luna said after Rainbow clam down.

The Contact was cut and Rainbow rod up the elevator. She walk over the Sector 6 elevator and rod down it. Unknowing what secrets it hind from her last time she visit.
