"You again!?!" Beast Boy cried in disbelief as he saw Mystery. "Didn't the New Titans beat you up?"

"Yes, they did, but now I have the jewel, I can leave, and that time, they can't follow me! Ha ha ha ha! I shall rule the universes!" He roared with laughter.

"Um, do any of you know the number for a mental hospital? I think the guy needs to be locked in a padded cell." Beast Boy asked his teammates.

"Hey! I heard that! Anyway, I can't be stopped! Ha ha ha ha!" Mystery laughed. He threw the staff, which is smashed up pretty badly. The staff dashed toward the Teen Titans.

"Don't that guy ever learn?" Raven asked as the staff crashed, for the third time, into the invisible barrier.

"Apparently not." Robin answered. "Teen Titans, go!" He shouted. "Get that jewel!" They raced toward Mystery. He cackled and limped out of the way. Even if he was hurt badly, he still moved with speed that's fast compared to the Flash.

Robin swirled around and tried to attack Mystery again, but he grabbed him by his arm, and threw Robin some twenty feet away. He did the same with Beast Boy and Raven. With Starfire, he threw her into a car wash, which, luckily, has no cars inside. But still, she was sidetracked. Now only Cyborg remained.

He shifted his right arm into his sonic cannon and aimed at Mystery. As he fired, Mystery dodged the sonic bolt, and then grabbed Cyborg's left arm. He released a high electrical shock like last time, and like last time, Cyborg's systems crashed. Mystery's glory was short lived after Cyborg fell to the ground, because he heard a cry that was welcomed by citizens, feared by villains back at his universe.

"Titans Together!"

With that cry, Nightwing appeared. He managed to punch Mystery several times before Mystery laced upon his right arm and threw him about twenty feet away like Robin. But a green tiger then slashed his back.

Mystery screamed in pain, but still he managed to grab the Changeling's right hind leg and toss him nearly fifteen feet away. He threw him hard enough, the Changeling was too injured to get on his feet. Enraged, Princess Koriand'r punched him straight through a SUV. Mystery snarled; grabbed on Starfire's left arm and threw her into the car wash where the another Starfire is.

He could heard the sound of the girls crashing into each other; they would be down for a period of time. He grinned; a sinister smile, and began to channel his power into the jewel that he stole. When the normally black jewel glowed bright blue, he brought it crashing into the ground, where an enormous electrical shock roared from. It swept through both Cyborgs, Starfires, Robin, Nightwing, Beast Boy, the Changeling, and the younger Raven. They all screamed in pain before blacking out.

"Wait... where's the other Raven? I didn't hear her voice." Mystery puzzled. But then he froze as he heard the voice. It was filled with pure hatred and fury toward him. Never such a voice had been heard before. It truly frightened him.

MYSTERY!! How dare you to attack my friends! How dare you! For that you will most surely pay!! Raven roared, her voice filled with pure hatred, her fury blinding her to anything else but Mystery. In her mind there is only one thing: kill. The half-demon's eyes shone red with bloodlust and fury as she moved in. Her soul-self tore itself from her body and rushed at Mystery.

"No!! NO!! NOO!!!" He cried as the soul-self enclosed him. "NOO!!!" The ice-cold black mass had enclosed around him; nothing could open it useless Raven decided that Mystery had enough. Bright electricity volts could be seen from the birdlike entity. The others struggled to awake and to their feet as they stared in horror at what Raven is doing to Mystery. Nightwing, the Changeling, the older Cyborg and Starfire all watched with grim sadness, for they know what is happening.

But for some strange reason Raven's eyes returned to its normal ice-cold blue and she slowly released the jewels Mystery had stole, but she kept him in her soul-self. She picked up one jewel and walked over to the younger Raven.

Here is the jewel he had stolen from this universe. She said, placing the black jewel in Raven's hands. She then turned to her team. Come, friends, and let us return the stolen jewels. I shall open the portal. As she spoke, a dark portal opened.

"Thanks, Raven. Okay, guys, let's go home. Now, about you kids, I just want to say thanks for helping us to catch Mystery." Nightwing said, extending his hand to Robin.

"You're welcomed." Robin smiled as they shook hands.

"Yes, you are most welcomed, and you shall be most terribly missed afterward." The younger Starfire spoke up. The Teen Titans watched as the New Titans each stepped through the portal; Nightwing first, then Starfire, Cyborg, the Changeling, and lastly Raven with Mystery in tow. After the older Raven has disappeared, the portal began to dissolve away, as the universes was returned to normal. The Teen Titans knew that they would not forget this, ever.
