Roku went over to the TARDIS as instructed.

Some the shadows that were slashed at disappeared, while few still remained. 

Hunter noticed how his shadows were decreasing in numbers. Now, he was frustrated, but he didn't show it. He flipped open his spell book to see if there was anything stronger than shadows. He was searching for a spell that would summon the undead. [i]Zombies? That could work, but they are slow.[/i] He thought to himself as flipped to another page. [i]Vampires? Maybe, but they'd be too obsessed with blood.[/i] He called his shadows off before walking away to find a new hideout.

The remaining shadows threw a few last needles at Arin before they were called off. Most obeyed, but one stayed. (Hey, I rhymed. Or at least I think I did). The last one wanted to continue fighting until it heard its leader snap his fingers. This was the only one that could talk. "But....this girl is interesting. I wanna keep going!" It shouted in protest.

Hunter walked over to the talking shadow before looking at Arin. "You might have won this time, but I'll make sure you fail next time, dino-boy." He said as dragged the last shadow by the ear to wherever he was going.

Arin heard what the necromancer called him. Dino-boy? He just shrugged at the nickname before turning his girlfriend, but winced before he could say anything. He looked over at his left shoulder to find a few needles there which made him slightly annoyed. He attempted to pull the dang needles out.

Mikey looked at his group. "Hey, you can't just leave me alone with Shredder here." He said.

Kirby had transformed into Needle Kirby after swallowing some of them. He heard Mikey and ran over to where he was and began throwing his own set of needles at Shredder.

Shredder did not expect the needles. "Ow! Ow! Ow! Ow!." He shouted as he looked for whoever did that. He found a pink fluffball with a needle helmet on its head. "What's with the pink thing?" He asked.

Mikey shrugged in response to Shredder's question. "I don't know, but he appears to be helping me." He threw his Numchucks at Shredder who stumbled backwards before the Numchucks returned to Mikey's hands.

Shredder knew he had only two choices left, keep fighting or retreat. He chose retreat. "You and your friends haven't seen the last of me." He said as retreated back to his Headquarters where his leader(Kranng) would be awaiting his victory or failure.

Alexander saw the Deleks and hopped off Five's pet before running over to the TARDIS. He had no fighting experience therefore he had no idea what to do. He decided to only follow the Doctor's orders for now.
