Jessica ran up to Bucky and asked if he had a plan.

'I don't have a plan,' he stepped back and stared at the metal men killing and chasing people.

'You will be destroyed,' they heard and so they rotated around to see a Cyberman point its arm at the pair.

With one fire, green fluid shot out of the Cyberman's gun on its arm.

Seeing the green fluid fly towards the pair, Bucky grabbed hold of Jessica's waist and pushed her to the ground. He fell on top of her and winded her but thankfully the green gunk landed just beside them. He helped the female up as the Cyberman pointed its arm again. The pair sprinted off and the Cyberman kept missing them.

'What are we going to do?' screamed Jessica as she and Bucky jumped behind a UNIT van.

'Hang on,' the American said. 'All of the sarcophaguses opened. Kate!'

Abandoning a petrified Jessica, Bucky rushed back inside the building as a Cyberman tried shooting at him.

'Stay away from me!' screamed Kate as she picked up a box and threw it at the Cyberman.

It made the silver monster move back slightly but it soon continued its journey across the room.

Shrieking, Kate then tipped the table over. It was a heavy table so it took a bit of time but when she did, the Cyberman fell over. Thinking she was successful, she made her way to the door and started hitting it again. However, she turned around and saw the Cyberman stand up.

'Kate,' she heard Bucky shout from outside. 'Are you in there?'

'Yes,' she confirmed. 'Get me out! The key is on the shelf outside and there's a Cyberman in here with me.'

Sticking the key in the latch, he twisted it and the door flew open. Grabbing Kate, he whisked her out of the room and then he clutched hold of the disintegrator that was also on the shelf. Kate knocked it out of his hand and then kicked the monster in the chest. It crashed down the floor and then its head came off.

'I'll call the scientific sector and ask them to extract the green stuff and to create a cure for Clara.'

'What are these things anyway?' asked Bucky as he and Kate stepped out of the historic building.

'They're called the Cybermen,' she watched as a beefeater hit one of the metallic brutes with his hat. 'They've tried to destroy earth on previous occasions but this time I think White Cobra are behind it all. I'm just wondering why they had 21 Cybermen hiding in chrome sarcophaguses.'

'Well that's what I said,' Bucky watched from the door frame. 'I think White Cobra wanted UNIT to take the sarcophaguses back. On Steve's SHIELD there was a black device that counted down and when it reached 0 the Cybermen emerged and attacked everyone here.'

'So White Cobra's plan was to let the Cybermen attack everyone at UNIT HQ?'

'Sounds like it.'

Instantaneously, a beam of red light shot past their heads. It hit the wall above them and a few bricks cascaded onto the floor. Spotting Jessica hiding behind the van, he led Kate to it and they dived behind it, watching the Cybermen through the van window.

Suddenly, the 20 Cybermen stopped what they were doing and stood still. As the sound of a rocket launching filled the air, the soldiers and scientists watched as the Cybermen lifted themselves into the air and the swarm flew away into the distance.

'Now what the hell is going on?' asked Jessica.

'I'm not sure,' said Kate, so Bucky and Jessica stared at her. 'But White Cobra have planned something with these Cybermen. It's my job to find out what. I'm going to pay them another visit.'

As the pulsating alarms rang out just like a few nights ago, White Cobra guards rushed around the base. As the man in the dark suit came rushing around the corner, he turned to see a woman in a chair sitting in the middle of the chrome corridor. She had blonde straight hair and she was wearing a dark blazer and blue shirt underneath. He recognised her instantly.

'Kate Stewart,' he approached her as the guards grabbed hold of her. 'What brings you here?
