Beast Boy sat by Starfire's bed, he had known her for almost three years, he knew that, much like Superman, Starfire's powers increased by our sun's radiation making her a more powerful and almost unstoppable heroine, yet someone… or something was able to put her in a near-death condition, something that had him both nervous and scared, if whatever was it that attacked Starfire could do that to her… what could it do to the rest of the Titans? He knew that Raven had more power than he imagined but yet… who or what hurt Starfire? He was so concentrated in his thoughts that the sound of the alarm made him jump from the chair, turning into a cheetah he ran to the main room where Robin was already checking the monitors.

-What's going on? – He asked

-I don't know, something broke the perimeter but I can't see anything on the screen. –the boy wonder replied.

-What about using that thing Cy says can show your heat?

-I already tried the heat sensors and got nothing…

Unbeknown to them, a transparent figure moved on the corridors of the Tower, at the same time the T ship landed in Tameran, Cyborg and Raven where escorted to the Chief who allowed them to see Blackfire, the teenager was sleeping in her cell.

-Just leave that trash you call food there… I'm not hungry… and bring me another pillow…

-We need your help –a voice very well known to her said.

The girl turned around startled.

-What are you two doing here? –she asked.

-Starfire was attacked and if she doesn't get a transfusion soon she may die in a couple of days.

Blackfire turned her back to them.

-So what? –she said.

Raven frown.

-We need you to give her some of your blood. She's your sister so I assume you will want to help her.

Blackfire shook her head.

-I can't…

-What do you mean you can't? –Cyborg replied

Raven extended her hand and with her powers raised Blackfire from the ground and after slamming her against the wall she began to choke her.

-Stop… it…

-Starfire is a dear friend… if I have to drag your dead body back home to get your blood for her I will… believe me… you won't be missed here…

-Raven stop –Cyborg said

Blackfire was desperately fighting against Raven's power, gasping for air.

-st.. op…

-RAVEN ENOUGH! –Yelled Cyborg as he forced Raven's arm down

Blackfire fell to the ground and gasped for air.

-you… idiot… it's… it's not that I… don't want to… it's bec… because… I can't…

Raven walked to her, her hands glowing with dark power.

-Why?

-Have you ever heard… about the techno virus? –she asked.

Cyborg's eyes opened wide.

-I heard about an incident near New York a long time ago… something about a school for gifted children… but it was stopped... Raven you were in that school…

-I left Xavier's school long before that happened… but what does that have to do with you? – Raven asked.

Blackfire told them about the time when she was wandering in space and got caught by a strange machine that took her to an abandoned planet where a being calling himself Apocalypse used her as a guinea pig for a newer version of the techno-virus.

-It was… shortly after I escaped from here… after my defeat against Star… the wedding thing remember? You don't have a clue of the hell I lived… he was surprised that I survived the infection… one day he just left… with the little power I had I was able to break free… weak and sick all I could do was fly back here… I don't know how much I'm going to live… sooner or later the virus will find a way to overcome my immune system and then…

Raven was silent. Cyborg approached and before Blackfire could do anything he took a sample of her blood.

-OWW! What are you doing?

-I promise I'll find a cure…

Blackfire got up and glared at him.

-So then you can save Starfire at my expense right?

-No. So I can save Starfire the pain of losing her sister.

-YOU FILTHY LIAR I… UGGH!

Blackfire fell to her knees in pain, Raven tried to help her but Cyborg stopped her and took her back to bed.

-We don't have much time, the infection is growing.

Later, Cyborg was preparing the T Ship for departure when Raven approached.

-Good news, they gave me this, the medic told me it'll help Starfire increase her blood recovery.

-Either way we must help Blackfire as well. Get in, we're going back home.

Raven nodded and moments later the ship was on it's way back to earth. In the Titan's Tower Beast Boy is walking back to the medical bay when he crashed against something.

-Wha…

Two green eyes flashed and a net was fired out of nowhere, the changeling was able to turn into a fly before the net contacted him, without delay he returned to the main room just hearing the impact of energy blasts behind him.

-What's going on? –Robin asked.

-There's something near the medical bay!

-What?

-I COULDN'T SEE IT BUT IT FIRED A NET AT ME!

-Star is in danger… COME ON!

Robin's words where not far from the truth, in the medical bay a stealth figure watched the unconscious form of the Tameranian teen, with a move of his hand a metallic claw appeared, for any observer all that could be seen was a metal claw raising to strike at the girl…

To be continued…
