It had been raining for several nights as if a prophesy had just been released. Much to the Titan's joy, things had been quiet otherwise. The most they had to stop in the past few nights was the occasional break-in, and they were thoroughly enjoying their free time.

However, as with many good things, it did not last long.

It was another damp, dreary night when Raven, interrupted from her usual meditation, sensed a new presence in her room. She pretended to remain in her state, as to try and scope out the opponent's weakness. Its gender was a mystery, but it overall had a human-shaped body. She could tell it was covered in fur, and had a tail with pointed, alien-like ears on its head. Whatever it was, it was sneaky, and any creature other than Raven would not have noticed its presence. It walked up to a table and placed something on it.

"Azarath, Netrion, ZINTHOS!" Raven chanted, the table was lifted and used to throw the creature through the window. She walked over and saw it shift into what appeared to be a large bat, although it was hard to tell in the darkness. As it flew into the distance she noticed the slight gimp in its flight, and the blood on the broken window panes. Robin ran in.

"Raven!" He shouted, "What happened?"

Raven picked up an envelope that had fallen off the table, "Get the others, something weird is going on."

And now for the titan's theme song!

When there's trouble, you know who to call ...

What?

Oh, right, the story.

Sorry.

Sunrise came and the Teen Titans gathered in the living room. Each one had received the same odd envelope, although Cyborg was busy analyzing the blood that was left on the broken glass.

"So ..." Began BeastBoy, "Who wants to open theirs first?"

"Perhaps it is a trap of the booby kind?" Said Starfire. BeastBoy raised an eyebrow.

"I think she means booby-trapped." Said Robin, "And I doubt that's the case. If the creature intended to trap us, it wouldn't have given an envelope to all of us."

Cyborg walked in, "Hey, guys. I have the results."

"And?" Said Robin.

"It's ... weird. Whatever it is, it's female, but I tested the DNA with that of every creature on earth, and it doesn't match any of them ... directly. If anything the DNA is consisted of codes from several different animals, including humans. Actually, the closest match I found was with that of BeastBoy's blood."

"Sweet!" Said BeastBoy, "I have a sister!"

"For all we know, your 'sister' is evil." Said an annoyed Robin, "We need to open these envelopes before we assume anything.

"I already did." Said Raven, "You're not going to be happy." She tossed him one of the letters. Robin read it in a matter of seconds before crumpling it up and walking out of the room.

"What does it say?" Asked Starfire.

"It's a cry for help." Said Raven, "From Gotham city."

Author's Notes:

My first fanfic! WAAAH! Please don't kill me TT

In case you're wondering, the creature in Raven's room was, in fact, a shape-shifter like BeastBoy, but she has a few extra powers. This will end up as a factor later, so pay attention!

I will end this footnote with a hope to see you again note. There will be a bit more action later on, so don't worry if it seems to drag. Meanwhile, consider this: if Robin were sent to a future without the Titans, what would the world be like?

Maybe you'll find out ;)

Adieu!
