Alarms were ringing everywhere as the Avengers pulled themselves up off the floor. Sean was already making his way towards the monitors. "Do you have visuals on the attackers?" he asked, scanning the screens.

Fury was barking out orders into his com "Status report!" He came up behind Sean, "And pull up all visuals on the attackers and send it to conference room A." He gave him a level stare "I really hope you aren't screwing with me."

Sean ignored him and focused on the images appearing on the screen. A couple of hulking humanoid shapes covered in crude symbols lumbered down the halls of the Helicarrier on several screens. He cursed quietly under his breath.

The good captain spoke up "Um... What are they?"

Clint leaned forward to get a better look at the images "Whatever they are they have the worst paint job I have ever seen."

"That's not paint, its blood. Where's your sprinkler control?" Sean was searching around frantically.

Fury raised an eyebrow "Why exactly do you need the sprinklers for?"

The bridge officer reported in "Sir, there are a dozen um... hostiles moving towards the bridge. All attempts to stop them have failed so far." There was a long pause "We could really use the Avengers help." Tony, Thor, Steve, Clint and Natasha rushed out to assist.

Bruce Banner looked nervously at the remaining people "I'm not sure that the other guy would be much help in this situation. Sean gave a small laugh but otherwise ignored him.

"Again...What are they?" Bruce asked uncomfortable with the tense atmosphere.

"They are called Constructs. They are magical creations made from scrap. Nigh unstoppable and probably capable of going toe to toe with the Hulk without difficulty. Hopefully the sprinklers will wash away the blood. Without the symbols the Constructs won't function." Sean explained "This is the only thing I can think of to do. I was never really the magically type. Damn I wish Reagan was here." He turned towards Loki "She didn't teach you anything helpful for this situation did she?" he asked hopefully.

Loki shook his head "She never mention anything about fighting Constructs. I'm sure that I have sufficient training to take them on."

Sean taped rapidly on the keys, pulling up the Helicarrier's emergency systems and triggering the sprinkler system unleashing a flood of stagnant, artificial rain on everyone. "OK, that should do it." He looked up at the screens again and swore just as a bridge officer contacted the conference room again.

"Director Fury, the... creatures are splitting up, we have pairs heading towards the engines, the hanger and armoury now. Shit! Sir, we are showing additional attackers! They appear to be Chitauri! They've just appeared out of nowh..." the signal cut out dissolving into static. Fury cursed under his breath and did the quick arithmetic of leaving the two in the room unguarded versus not ending this attack quickly. Banner will have to be enough. He thought.

He turned to the wary scientist "Make sure they don't leave the room, I don't care if you have Hulk out to do it. The Helicarrier is being torn apart around us as it is." With that the SHEILD director rushed out to join the fray.

The three remaining men in the conference room looked at each other awkwardly before the floor began to vibrate, heralding the five Constructs stampeding up the hallway just outside the conference room. One skidded to a halt and swung back around, crushing a two foot section of door frame under its grasp. "I suggest we run, if that's alright with you."Loki said.

"...We have pairs heading towards the engines, the hangers and armoury now." Tony peeled off from the rest. He was finding that he did not particularly like fighting in tight spaces in his armour; it gave him no room to manoeuvre. He couldn't fly so he was forced to run through the halls. He came up behind the group that was heading for Engine Number One. A blast from his gauntlet repulsor tore apart the arm of one of the creatures. They spun around readying to attack. Another blast caught one full its torso, splitting it in two. The two halves continued around for a moment before the artificial rain destroyed the symbols powering it. The one armed Construct lashed out, grabbing Tony's helmeted face and slamming him into a wall. He saw stars and his HUD flickered. "Ok, that hurt." The creature was now slowly crushing Tony's helmet and with it his head. He grappled with his attacker's arm trying desperately to pull himself free. He was forced to blast it off with his chest reactor. He collapsed onto the ground as the creature's hand fell away now that the rest of it was cinders. Tony scrambled back up to rejoin the fight.

Clint and Natasha were well ahead of the rest of the Avengers and nearly at the bridge when the sprinklers came on soaking them. It did not even slow the pair down. Meeting up with Maria Hill they organized the defence. The SHEILD agents had just reached the bridge before the first wave of attackers. Guns opened fire biting into the Constructs marching forward. The firearms were having as much of an effect as they had been earlier. The Constructs were unconcerned with the bullet holes riddled in their bodies. "It's still not working!" Natasha yelled over to Clint on the other side of the room.

Clint notched another explosive tipped arrow. It flew through the air embedding itself in chest of one of the creatures. The resulting explosion blow away much of the head and upper torso but the legs and one arm continued to move. I'm going to run out of explosive tips if this continues. Need to try another tactic. "We need to come up with a new plan."

Steve was having a hard time maintaining traction in the wet conditions. Smooth floors and water meant that he was limited on how fast he could move. He could see Thor vainly trying to keep his footing too. Thankfully their weapons of choice meant they did not need to move about much in order to hammer at the enemy. The hanger was already being trashed by four large Constructs. The symbols on them were already smeared and running. Steve threw his shield at the closest. It turned around supernaturally fast and pulled the shield from the air. Tossing the shield to the ground it lunged for Steve. Molnjir's impact caused it to stumble and gave the good captain enough time to dodge its blows. The other three took this as their cue to join in. Soon the two were trading blows and trying to avoid the four inch talons that ended each 'finger'. The captain made a dive for his shield laying only feet away. He brought it up in time to stop a lethal strike from above. Thor tore the arm off one and bashed in another with his hammer.

The agents on the bridge were running dangerously low on bullets. Of the six Constructs only two had been disabled. Though none of the agents wanted to say it but they couldn't hold off the rest of them for much longer. Suddenly one of the Constructs exploded from behind. Nick Fury stood behind the attackers carrying the destroyer gun. With the Director to help them now the last of the Constructs were quickly taken care of. "Now let's clear out the rest of the trash."

Bruce followed after Loki as they fled from the pursuers, he was not letting him out of his sight. He was only barely staying in control but he would be more useful as Banner than the other guy. Loki was making a lot of sharp turns to try and throw off the creatures behind them. The animated piles of scrap were not able to corner very well especially with the water pouring down. He was not all too sure where they were going but Loki certainly seemed to and he was content to follow. They eventually ended up looping back around to the conference room. Loki quickly headed over to the monitors to check up on the others. Bruce took a few deep steadying breaths hoping to keep calm. He caught movement out of the corner of his eye. Two Chitauri stood in the doorway. He positioned himself between the two in the doorway and Loki at the computer. He could just see Loki turn to face their new attackers and bring his hands up in front of him. Before anyone could move everything seemed to go dark and Bruce fell to the ground.

Loki was completely and thoroughly lost. He left the conference room with the purpose of locating Sean in the chaos but he hadn't found him had no idea where anyone else was. A repulsor blast shot past his head. He spun around to see Tony standing behind him. "What was that for?" he shouted. Tony only shrugged in his armour. Loki narrowed his eyes at the clearly childish behavior "We may as well head back to the conference room then." The armoured man lead the way back to the conference room. Turning into the room Loki stopped short at the sight of two Constructs leaning over the prone form of Dr Banner. He felt a twinge of guilt that the good doctor was in this precarious position because he had availed himself of the opportunity to get a modicum of revenge on the beast for their last encounter. He threw a conjured dagger straight into the first attackers. The attacker dropped like a stone to floor or more correctly a pile on inanimate metal. Tony took out the second with a well placed blast

With the battle over everyone had gathered back in the conference room. Bruce had woken up and was now sheepishly sitting in the corner. He thought it was a bit of a blessing that the other guy had avoided making an appearance. Sean looked from Bruce to Loki and pursed his lips. "Ok I'm going to need some explanation from you two. Right now!" Fury ordered. Loki and Sean looked at each.

Loki turned away "Never you mind." He said crossly. Sean gave him another look. Now was not the time to angering potential allies turning them into potential roadblocks.

Fury crossed his arms "This is not a request! My ship has been attacked and these creatures were clearly after you! YOU ARE GOING TO TELL ME WHY!" Loki continued to sulk.

Sean sighed when he noticed the set expression of everyone around. The Avengers were not going to let them go without answers. "They're trying to kill us." This was met with sarcasm.

"I think we are going to need a bit more than that." Fury said. "We can start with who you really are" pointing to Sean "And you are doing here" pointing to Loki.

Thor chimed in "Yes how ever did you escape from your prison brother?"

"Asgard must have terrible security." Was all Loki would say.

"I'm not sure as to why the Chitauri are here controlling the Constructs. Do you know why they'd take her?" Sean asked Loki.

Loki shook his head. Thinking about why the Chitauri would take Reagan was terrifying. He knew how powerful they were but how did they know where they were going to be? How did they know to grab Reagan? "As for what we are doing here, on Midgard, I have already explained we were going to the opera." This was greeted to a round of incredulous looks. "Reagan asked me to show her this little world I was so eager to conquer." He took a deep breath, it was going to be hard. "I failed to conquer Midgard, I will be punished for this failure. I suspect that the Chitauri are here to meet out that punishment."

"The Constructs are usually a creature created by enemies of my people, mainly because they aren't alive they are not susceptible to some of our... abilities. If the Chitauri have been given control of an army of such creatures then there is something larger at foot than simple revenge for failed promises." He pointed a finger aimlessly "I...have an idea on what that could be."

The Avengers looked at each other, it was beginning to look like they were going have to work with Loki.

"Sit down. We have a lot to talk about." Fury said forcefully.

The Avengers team up with Loki and Sean and plot their next move.
