Disclaimer: I Don't own Teen Titans, if I did Slade would have been in Season Five more and Brother Blood would have had more appearances.
The Steel City Penitentiary, certainly lived up to its name, the entire building was made literally out of steel that was rusted into a dark, sickly color, giving off the feeling of corruption and decay that was so prominent in the city. The guards reflected so as well, as corrupted as those they kept in check, many taking sadistic pleasure torturing the criminals.
The exception was in the deepest, most heavily guarded cell, actually hidden several levels below the ground, behind in a triple-reinforced steel door. The criminal held in there reeked of unholiness that the guards did not dare try and test their luck.
In the cell was Brother Blood.
The broken cybernetic body of Brother Blood lay hooked up to various sorts of machines designed to repress his psychic abilities, S.T.A.R labs and Wayne Enterprises contribution to keeping one of the world's greatest cultists and terrorist leaders away from innocent people. Still his powerful mind was just barely able to bypass the machines and send out a signal for help.
The sound of an explosion signaled to him that his salvation had arrived.
Ten of what appeared to be ninjas rushed through the hole made in the wall, into the prison, dodging various shots from the guards' overly fancy laser guns. One was shot strait in the back of the head, causing much of the head to explode revealing only wires and circuit boards. With the revelation that the ninjas were robots, the few uncorrupted guards began firing with much more lethal intentions, destroying two more robots.
One ninja, who appeared to be the leader due to his different attire, ran down the corridor to the main holding room, while the others ran head on toward the guards. The ninja-bots were extremely skilled but were horribly outnumbered, and a well placed shot in the head signaled the end of the battle.
The guards stormed into the main holding room to see the ninja-leader typing on a device on the wall. With the last push of the button all the cell door flung open releasing hundreds of convicted criminals, eager for some payback at their old captors.
While the majority of the guards were quickly overwhelmed, one managed to notice through the chaos, the leader entering the elevator to the subterranean level.
'But the only thing down there is…oh no!' the guard thought.
He quickly fired a skillfully accurate shot at the face, which made it that much more surprising when the ninja displayed surprising agility (especially in the confines of an elevator) and dodged the blast just before the elevator doors closed.
Deep below the ground in the dank subterranean levels, the elevator doors opened, revealing to the ninja-like man a small corridor with a heavily reinforced door at the end flanked by two more unusually heavily armed guards who raised their weapons when no one came out of the opened elevator.
The guards looked at each other in bewilderment, growing tenser at the resounding silence. The only time that elevator was used was to change shifts, and that wasn't for another three hours.
A device resembling an unusually large shuriken struck the wall next to the guards, the sharply stylized S symbol on it glowing before exploding into a million pieces, killing the guards and destroying the door.
The ninja-like man stepped through the thick smoke created by his projectile into the holding cell.
Brother Blood looked up at his savior and grinned.
"Glad you made it." Blood said pleasantly. "Long time no see, Slade."
