What happened last chapter:

All of a sudden the sky lit up with a powerful bright light. "Shield your eyes!" Raven yelled, covering her eyes with her arm, Robin doing the same. "What's going on?" Robin asked in fear. "You will see...soon", she replied. Just then the light vanished. They both looked around them, spotting the villain.

Inside the tower, the alarm went off, sending the 3 titans to the big computer screen. Cyborg checked the location.

"The villain's on the roof of the Tower," he reported, turning to face the others. Beast Boy's eyes widened.

"Dude, isn't that where Robin and Raven are?" he asked, his voice rising in panic.

"Yeah, let's go!" Cyborg replied, already running towards the roof with Starfire flying ahead of him and Beast Boy changing into a dog to follow behind them.

Meanwhile, on the roof:

Raven just stared at the villain. It had been so long since the last time she'd seen him, years-she'd stared at him then, as she was doing now-and still he was the same...

Flashback:

It had all started on Azarath. They'd once been close friends in their childhood years-that is, until he'd betrayed her.

When Raven saw him that final time, he seemed...different. She couldn't explain how, exactly, but he didn't seem like the best friend she once knew. Even knowing this, she hadn't expected it. It had all happened so fast. One moment they'd confided everything in each other, and now here she was, covered with scars he'd given her.

She fell to the ground, clutching her arm where he'd just dug his claws into her. She glared at him, her eyes burning with rage. She may not have known or felt many emotions, but this particular emotion was familiar to her.

"Why...why are you doing this, Caim?" She shook her head and continued to stare in anger and bewilderment at her former friend. "You promised me we would always be friends!" She stood up and clenched her fists. She couldn't believe what was happening, what she was doing. Caim smirked.

"We were only kids then. It was just a dumb promise we made when we were foolish and young. We aren't children anymore, look around you, Raven! We're teenagers now, it's been years since we made that promise. Did you honestly think it would last forever? I always thought you wouldn't be that stupid." He laughed cruelly while Raven bowed her head in regret and shame.

"Yes, I did. I guess that was my mistake," she said bitterly, "but you never told me why you're hurting me like this!"

"Things change, you know that. Nothing can last forever, not even friendship. Now, I know that doesn't explain everything. Why am I doing this? Well...to tell you the truth, I really don't like you. In fact-I just plain despise you!" he replied, running towards her to injure her with his claws again, and then flying up into the air with demonic wings to shoot magical lightning her way.

Raven didn't have enough time to escape from his attack or defend herself with her powers. All she could do was survive the powerful attack, and force herself to get back up afterwards.

"Not giving up, eh? You will regret that." Caim threatened, still airborne.

"I doubt that." Raven stood her ground, and as she cried out, "Azarath, Metrion, Zinthos!" her eyes glowed white. Her hands were also glowing as she lifted a boulder with her powers and sending it right at him, knocking him to the ground. She watched him get back up.

"I see you're getting better, but you're still not good enough!" he shouted as he took out his sword. He charged at Raven again and quickly sliced the sword across her abdomen.

She fell once again to her knees, putting her hand over the gushing wound with her other hand placed on the ground to hold her up.

"You can't defeat me, and nothing-no one-ever will," he declared.

"Don't try to reassure yourself, Caim. There will be a day when I will be the one to defeat you!"

"Then I'll spare your life to give you the chance to live up to that threat," he said as he laughed.

End of Flashback

His laughter could still be heard in her mind from that day, a cruel, wicked laugh that made her shiver when she heard it.

Caim gazed at Raven, and as he slowly walked near her, he reached to grip her chin tightly with his hand. The feeling of his claws on her face made her shudder.

"It's good to see you again, Raven," he said, wearing that same old smirk of his.

"Don't touch her!" Robin cried as he pulled out his Bo-staff, preparing to fight him. Caim let go of her face and turned to Robin.

Robin continued, "I don't know who you are or what your plans are, but I do know that you're an enemy and I need to bring you down!" He knew Raven had told him that even all the Titans together couldn't defeat him. But he knew he had to try.

The other teen titans came running up on the roof, seeing Raven and Robin with Caim.

"Raven, Robin! Is everything alright?" Starfire asked with panic.

"Everything is just fine", Raven replied sarcastically.

Beast Boy changed into his human self. "Why aren't we fighting?" Beast boy asked, confused.

"Even if we did fight, we wouldn't win," Raven answered hopelessly. All of the Titans stared at her in shock with the exception of Robin, who was focusing on the enemy.

"That's not like you, Raven. Why wouldn't we win?" Cyborg asked.

"Yeah, why not?" Beast Boy mimicked.

Starfire said nothing and continued to look at her in hope for an answer along with the others.

Raven sighed in exasperation. She didn't want to tell them, but she had to anyway. "I've fought him before and he was far too powerful for me to beat him. It was difficult enough when I was alone, but now he's probably gained more skills and powers, who knows how strong he is now? All of our powers combined probably can't overcome him. If you do choose to fight him, you'd better watch yourselves."

For a minute all of the Titans looked scared, but fear was quickly replaced with determination as they turned to face the villain. Robin was charging at Caim before he knocked him out of the way.

"For all of you that don't know me, I am Caim, the all-powerful demon. I come from the planet Azarath, and I suppose I could once be considered Raven's...friend."

He grinned evilly at Raven when she added, enraged, "Until you betrayed me!"

"And then defeated her, in a battle I'm sure she'll never forget," he added, concluding his introduction to the Titans.

"Like we even care who you are!" Beast Boy retorted.

"Oh, but you will care, when I take my plan into action. It's too bad Slade couldn't pull it off himself..." he said with a wicked grin.

Raven looked at him in shock. "You know Slade?" she asked.

"I knew him, yes," he replied.

"Knew?" She questioned. Caim nodded.

"That is, until I killed him and stole his plan," he said with a laugh. The Titans all gazed at him in shock.

"It wasn't the easiest thing to do when I wasn't as powerful as I am now, but somehow I managed to pull it off", he said casually.

"We may have lost the strongest enemy we ever had, but things have now gotten worse, a lot worse," Raven said.

Sorry if he doesn't sound so bad, or evil, I'm not so good at doing stuff like that, but I'm trying my best, he'll get a little bit eviler in later chapters though!
