A/N Just a reminder: any brother referred to by his full name is one of the jerk brothers. Leo's good brothers go by their nicknames. Anyway, here it is. Time for a little butt kicking.

As Raph began to circle his opponent, he knew he had to put aside the angry brother and become the professional ninja he'd been trained to be. Immediately he began to look for areas of weakness he could exploit to his benefit. To assist in this, Raph feigned an attack at his enemy's left side. Hmm, not bad, but not as fast as it could be. After just a few seconds, Raph repeated the motion to the other turtle's right side, but this time he didn't pull back. Score! Raphael hadn't been fast enough to keep Raph's sai from nicking his side.

With first blood now scored, the fight was one, full force. Raphael, Raph had to admit, was good. At first, the younger turtle was driven back by a barrage of kicks and punches that came with incredible speed. But Raph had an ace up his sleeve, if he were wearing any sleeves that is, and that was he had spent the past year under Leo's training. Under his older brother's guidance and tutelage, Raph had become stronger and faster than ever. And now it was time to put all that training to work, avenging his brother against the very individual who featured in Leo's worst nightmares.

With a quick flip, Raph landed behind his opponent. A strong kick to this shell had Raphael flying forward, into the wall. He immediately recovered, and turned back to face Raph, his sais flashing as he twirled them. Raph just smiled confidently, and mockingly motioned him forward once more. Raphael charged his younger version, only to be tossed unceremoniously over Raph's shell. Cursing, he came to his regained his feet. This time, however, he led his attack with his sais. With a clang of said meeting sai, Raph met him move for move. Using his better stance and leverage to his advantage, Raph pushed Raphael back a step, then delivered another punishing kick to his plastron. This time, when Raphael hit the wall, his weapons dropped from his hands. When he went to grab them, however, he was stopped by a sai suddenly piercing the ground directly between his hand and the lost weapon. He turned a dark look on his younger counterpart.

"Come on, old man" Raph taunted. "Let's try this the old fashioned way, mano a mano."

With a growl, Raphael charged, but Raph neatly leaped over him. A firm kick to Raphael's backside sent the other turtle face first into the wall. Again, Raphael approached, though this time at a much more controlled pace. Once he was in range, he unleashed a punishing volley of kicks and punches that left the younger turtle unable to do much other than defend himself.

By this time, the fight was beginning to get to both turtles. Determined to end the find on his own terms, Raph kicked it up a notch. Moving fast that ever before, Raph landed a set of double punches to his opponent's face that left his bleeding from the mouth where his lips were cut on his teeth.

"That," he told Raphael, breathing heavily, "is for what you did to Leo tonight."

Several punishing spin kicks left the older turtle nursing decidedly bruised ribs. "And that is for the way he flinched away from me the first three months he was here."

Finally, Raph downed his enemy with a sweeping kick that knocked Raphael's feet out from underneath him. "And that is for every cruel, heartless thing you've ever said to my brother that made him feel lower than dirt."

Panting slightly, Raph stood over his fallen, bleeding counterpart. "Keep away from my brother," he growled. "You lost all rights to him when he tried to kill himself because of what you did. Now, leave him alone with the family who truly appreciates what you so idiotically threw away." With that, Raph turned away and walked to where his brothers were waiting. Clapping Donny on the shoulder he said, "Your turn bro. Have at it."

Donny moved calmly onto the floor, bo staff in hand. When Donatello didn't move fast enough to join him, Mikey "encouraged" him with a none too gentle shove that sent the older turtle scrambling to regain his balance. Silently, the two turtles faced each other. For a long moment, no sound was heard beyond the heavy breathing of the two previous combatants. Then, without warning, Donny sent a lightening fast blow from his bo toward his opponent's abdomen. Donatello barely caught the blow on his own weapon, and it still left his arms aching and palms stinging from the strength behind it. Before he could fully recover, however, a second strike came from seemingly nowhere and landed harshly along his left side. Reacting on sheer instinct, Donatello returned the blow, only to have it smoothly turned aside by Donny's weapon.

For the next few minutes, the two purple clad turtles exchanged blows in what very well could have been a scene straight out of Robin Hood, only ninja style. All that could be heard was the clatter and clack of the two wooden staffs hitting each other, punctuated by the occasional grunt as a blow landed, and the muted sound of feet as the two turtles jumped and dodged to avoid each other's blows. It rapidly became apparent that while Donatello had strength on his side, Donny was quicker and more agile. Being slightly smaller than his counterpart, Donny was able to slip under Donatello's guard and deliver quick, stinging blows that left the older turtle off balance.

Once he had his opponent where he wanted him, Donny, following Raph's lead, began to punctuate his blows with an enumeration of his counterpart's sins in regard to Leo.

Thwack! A blow hit Donatello upside his head. "That's for letting Leo suffer for that wounded shoulder without helping him," Donny said grimly.

Thwack! A stinging blow landed on Donatello's right wrist, followed closely by one to his left. "That's for not standing up for Leo when he needed you."

Thud! The end of Donny's bo caught Donatello in the stomach, knocking the air out of him. "That's for every time you made my brother feel like a useless failure."

Suddenly, Donny's bo staff caught Donatello behind the ankle, knocking him onto his shell. Before Donatello could move, he found the tip of Donny's weapon poised a mere inch about his windpipe, the younger turtle's face a study in wrath. "And that," Donny hissed, "is for your part in tonight's stupidity, and the new pain is caused my big brother. Now, like Raph said, stay away from our brother."

And with that, Donny turned and marched off the floor.

As Donny made his way off he floor, Mikey flipped away from the wall toward the center of the room. "My turn," he cried enthusiastically. Turning to give his counterpart a snarky little grin, Mikey taunted, "Why don't you just give up now, dude. I'm just gonna whip your butt."

"In your dreams, JV," Michelangelo shot back. "You're only junior varsity. Stop and watch how the big boys play." With that, he set his nunchucks whistling and singing with a blindingly fast attack, which Mikey very deftly, and easily, avoided.

"Not bad, not bad," Mikey said. "Now, try this on for size." Mikey's attack was, if anything, even faster and more impressive, and Michelangelo barely had time to get out of the way. As it was, one of the 'chucks still hit his shell with a harsh smack.

"All right, it's on," Michelangelo growled, and the pair of two youngest brothers began to attack in earnest. For those observing from the sidelines, it was like watching a pair of armed pinballs go at each other, as both Mikey and Michelangelo jumped, flipped, and bounced all over the room and off the walls. The fight wasn't nearly as pretty as the two previous, and both combatants delivered a fairly equal number of winning blows. For a while it appeared the match was going to be a draw, when suddenly Mikey managed to entangle his opponent's nunchucks with his own, and pull them from the other turtle's grip. Automatically, Mikey moved in with a follow through: the same maneuver Michelangelo had been admiring that first morning he had joined Leo's new family for practice. Unfortunately for Michelangelo, he, unlike Leo, didn't know how to counter the attack, and as a result he ended up unconscious on the floor from being hit in the head with the end of Mikey's nunchuck.

"Huh, so much for the varsity team," Mikey said, looking at the unconscious form on the floor in front of him. Limping slightly from a bruised ankle, the result of not jumping fast enough to avoid his enemy's weapon, Mikey rejoined his brothers.

Raph turned a cold eye on the three bruised, bleeding, and, in Michelangelo's case, lifeless figures. "I suggest you keep your distance from Leo for the remainder of your stay. If I even suspect that you've caused him one second of concern, I will wipe the floor with your butts so hard it will make tonight look like a birthday party." And with that, the three victorious turtles turned and left the dojo.

After cleaning themselves up, Raph, Mikey, and Donny made their way back to Raph's room.

"Are they still breathing," Leo asked as his brothers settled on the bed around him.

"Unfortunately," Raph grumbled. "But we did wipe the floor with them."

Leo gave his brothers a breathtaking, though teary smile. "Thank you," he whispered as he drew them all in for a group hug. "Thank you for caring enough to fight for me."

"Any time, bro," Raph and the others assured him. "You're ours, and no one but no one messes with our family."
