Disclaimer: I do not own Teen Titans or DC Comics. Nexus is based on a character from a script I wrote for a short film for school. I only found out halfway through writing this story that there's already a superhero called Nexus from a separate non-DC comic series - any similaries between the two characters are entirely coincidental.

A/N: As well as being my first story on this site, this is the first story I've written in a long time, so forgive me if it's not that great. Righto, let's begin!

Chapter 1: Ice

The city square was overwhelmed by mass hysteria. The people screamed as they ran, slipping and falling on the icy ground. The buildings around them quickly became covered in jagged sheets of ice. Soon almost the entire square was empty, save for some unlucky people whose feet were frozen to the ground. They were now hostages of Mr. Freeze.

"I will ask once more, or these people will suffer. Where is the one known as Nexus?"

Mr. Freeze looked around the square, eagerly awaiting an answer. There was none. He smirked as he noticed one of the hostages, a boy, take a hot water bottle out of his jacket and place it near his frozen feet in a futile attempt to escape.

"I know you are here, Nexus," he boomed, raising his ice gun, "give yourself up, or..."

The ice gun suddenly vanished from his hand. Out of the corner of his eye he could see someone next to him holding the same gun.

"Or what? You'll freeze them? How very original! I've never heard that one before!"

Mr. Freeze was told he'd be dealing with an Australian. He turned and saw what he was dealing with. He looked around 16 or 17, with dark brown hair and pale skin. His suit of armour was matte black with glowing red piping, and he wore a mask over his eyes. Mr. Freeze found the costume's design suspiciously familiar.

"I'm sorry, I'm pretty new at this, but isn't simply freezing them a tad predictable? 'Ooh, look at me, I'm... Freeze Man, or... whatever, and I freeze people!' Sorry, I don't know your name, but seriously? Is that all you can do?"

Mr. Freeze wasn't sure how to respond to this person's cockiness. "That ice gun will only work when it is attached to my suit. You will be unable to use it."

"Really? Let's see about that!"

Nexus pulled the trigger. Nothing happened. Mr. Freeze seized the opportunity to grab his face and smash him into the wall. Nexus remained pinned against the wall while Mr. Freeze reclaimed his ice gun. Nexus tried to escape by striking him in the elbow, which did nothing except provoke a punch in the face.

Nexus lifted his head. "'Tis but a scratch," he said wearily. Mr. Freeze knew he wasn't joking. The description of Nexus he'd been given stated that his mutation made it difficult for him to take damage. He also knew that using his powers too much wore him out.

"Just come with me, and no one gets hurt," urged Mr. Freeze. Nexus frowned and said nothing. Mr. Freeze noticed him looking past his shoulder. He turned to find out what Nexus was looking at. It was the boy with the hot water bottle. The bottle vanished.

Oh no.

Immediately he felt searing pain caused by immense, burning heat. He screamed in agony as he fumbled with his gun while trying to remove his helmet. The burning clouded his concentration and caused him to panic. The helmet finally came off and he scrambled to remove the hot water bottle from his face.

He rolled himself onto his back and looked up at the figure looming over him. This couldn't be happening. He was running out of ideas. His only option was to negotiate. Make Nexus come with him. He needs to.

They have Nora.

"Please, you don't understand..." Mr. Freeze said as he slowly grabbed his helmet and put it on.

"Of course I don't understand. I don't even know who you are. Why do you want me?"

The sudden breeze of sub-zero temperatures from his helmet brought him back to his senses. He looked around and saw his ice gun near his head. He snapped off a shard of ice from the ground and thew it at Nexus to distract him. It worked, as it provided him with ample time to obtain his weapon. Nexus transported the shard somewhere behind him, and as he turned around, Mr. Freeze pulled the trigger. Nexus was frozen in a jagged block of ice.

Mr. Freeze stood up and took a transmat device from his belt. He already had one attached to his suit, but he needed to attach one to Nexus in order to take him with him. But before he could do so, he was suddenly struck by a green beam of light that sent him flying into a nearby car. He looked up and saw who attacked him.

The Teen Titans.

"Ah, Robin. The Boy Hostage. I see you've made quite a living for yourself."

"The only living you'll be doing is in a prison cell!" Robin replied.

Mr. Freeze couldn't afford for this to happen, so he fired his ice gun in their general direction. One of the Titans, a girl in an indigo cloak, projected a black forcefield that deflected the ice. He scanned the area for the other transmat, spotting it lying next to an ATM. He raced over to it, firing more ice beams at the team. He picked it up, but before he could take it back to Nexus, he found himself being mauled by a tiger. A green tiger. He dropped the transmat again, and in the struggle with the changeling, they both rolled over twice. He kicked the tiger away from him and stood up.

The transmat was broken. It had been crushed by the tanks on the back of Mr. Freeze's suit. He found himself being cornered by all five Titans.

"There's nowhere to go now," said Robin, "give yourself up!"

Kidnapping Nexus was going to have to wait. He activated his own transmat and dematerialised, praying that his masters would give him one more chance.

A/N: Sorry there wasn't much of the Titans in this chapter, but don't worry, there will be more soon! Feedback is appreciated!
