Spike glowers down her nose at the Kraang around them as she draws the mace and holds it high. "Who's first?!"

"I thought there were four turtles," Rahzar remarks, glancing at the group.

Stockman's eyes widen behind his glasses. "You fool, that's the girl! They gave her the serum!" He throws back his head and laughed. "I hope you were warned about the side effects, right? Cut off from the rest of your people?"

Raphael starts forward, but Spike thrusts an arm in front of him, stalking forward. Her large hand closes around Stockman's throat and she lifts him up. "The side effects seem to be beneficial," she growls in his face before tossing him into the Kraang. "To arms, guys!"

Michelangelo bounds in beside her, clearing the Kraang's forces as April slides in after him. "Yee-haw!"

Irma sinks her dagger into a Kraang brain and removes it, spinning to face a new enemy. "I'd say thirty Kraang."

"Twenty six," Donatello corrects.

"Okay, twenty six. Sue me."

Spike turns to a new foe as something comes into her peripheral vision. "Karai!" She bares her teeth and raises her mace high.

"Sanchez!" Karai steps back in surprise. "You look…How? How could you have…."

"Mutated," Spike supplies, blocking Karai's half-hearted sword swipe. "Is that the word you're searching for?" She shoves the smaller woman back.

"How?" Karai whispers.

"Your master murdered me," Spike snarls. "I died."

Karai starts in shock and aims a cut for Spike's knees. Spike reaches out and grabs Karai's wrist, stopping the thrust. Spike squeezes and Karai drops the sword. Spike picks it up and holds the tiny weapon, holding the mace over Karai. "Surrender."

Karai looks up at her.

"Surrender," Spike hisses. "You are beaten. You and the Foot. We are going to defeat your leader, and remove the hateful, hurtful, parasite. Look at what you've done. People have died. Not just me, innocents."

Karai's eyes flicker once, and Spike reaches forward and knocks the woman out, dragging her into a corner before turning.

Raphael and Michelangelo ferociously attempt to battle Rahzar, whilst Leonardo and Donatello fight Tokka. The humans remain taking out the remnants of the Kraang squad.

Spike races towards Leonardo. "Reportin' for duty, Captain."

"Give us a hand," he gasps, blocking a kick and striking at Rahzar's elbow.

Spike eyes the wolf. "Gimme space."

Donatello backs up and holds Rahzar's left arm while Leonardo grabs Rahzar's right arm. "Go!"

Spike goes in with her right cross punch, as hard as she can, into the dog's ribcage.

Crack!

Raphael and Michelangelo rush over. "Tokka's down," Michelangelo reports.

Donatello corners Stockman. "What are you working on?!" he demands.

Stockman glances around. "Nothing!"

Donatello frowns. "Seriously? How dumb do you think we are?"

Raphael brings his fist down on the computer equipment, smashing it. "Don, let's go! Cops are comin'!"

Donatello sheathes his staff and joins the others in the withdrawal.
