Leo was going on his daily exercise, but not before Master Splinter telling him to be careful since the foot are still looking for them. He's been fighting them nonstop for a long time now and soon he found himself up against some red ninja with hats on. He saw this and made a comment.

"Nice hats" Leo said

They soon attacked and Leo was forced to fight back against them with every once of skill that he possessed in him.

Meanwhile the others were waiting for him back at April's apartment and everyone was getting worried about him since he would usually back by now.

"Where is he? He should've been back by now" Raph asked

"Patience, Raphael, I'm sure that he's fine" Splinter said

"I don't think he knows patience that well" Bloom commented

After waiting for what felt like hours.

"Guys, something is definitely wrong, Leo should've been back by now" Mikey said

"I know this is a first, but I think that Mikey might be right" Donnie said

"Master Splinter" Raph said

Splinter remained silent.

"Go, find your brother" Splinter said

Bloom decided to go to since she was also worried about the young turtle herself.

Before anyone could head out, Leo's was thrown through the window injured. Everyone gasped in horror when they saw him.

They tried to ask who did this to him but he couldn't respond and Raph made the reckless decision to go out and make whoever did that to his brother pay.

"I'm going out to find out who did this" Raph said

"Wait" Leo said weakly

Raph jumped back down. He then told everyone the bad news.

"He's back…The Shredder" Leo said before passing out

Everyone gasped.

"Please don't tell me I heard what he said" Donnie said

"You did. Don't you know in the movies the bad guy always comes back" Mikey said

"Donnie we need to started to medical ninjutsu" Bloom said

"Right away" Donnie said

But before they could, Foot ninja appeared in front of them.

"Looks like treatment will have to wait" Raph said as prepared to fight.

Mikey and Raph started to fight the ninja but more and more kept coming. Splinter came in to help them but there seemed to be no end to them. The redhead looked a Donnie and told him to go.

"Donnie go help them" Bloom said

"But" Donnie said before being cut off.

"Don't worry, I'll heal Leo, go help the others" Bloom said

Donnie just nodded before going to help fight off the foot.

Bloom then started to use her medical ninjutsu to heal the wounded Leo. The turtle leader began to groan as his wounds started to heal.

April had to ask how bad his wound were.

"How injured is he?" April asked

"His life isn't in danger but he needs treatment now so I can't stop now. His right arm is broken along with some bruising. But he'll live" Bloom said

April sighed with relief that her friend would be ok. More Foot ninja came in and rushed towards the medical ninja, who gasped. Master Splinter jumped and did a midair kick to knock the ninja back out the window.

Bloom sighed with relief before detecting some chakra approaching Splinter and it looked like he couldn't see them.

"Splinter, invisible enemy, 50 degrees on your right" Bloom said

Splinter pumped some chakra in his stick and swung it, knocking back a tech ninja. More Foot ninja appeared through the window, and everyone was starting to get overwhelmed by their numbers.

"There's too many of them" Donnie said as he defended himself

"What are we supposed to do?" Mikey asked

"We need to get downstairs" Bloom said

Bloom was forced to stop her treatment for now. She then made some shadow clones to help the boys fight off the ninja. Meanwhile the real Bloom and April lifted Leo up and started to head towards the stairs.

The fight in the apartment continued as they managed to make it all the way down to the shop that April ran. But the ninja followed them down there and kept attacking. Bloom continued her treatment and Leo's injuries were starting to get better.

Casey managed to come in and help them fight off the Foot ninja. However, Hun appeared before them again and began to fight them. But Splinter managed to perform a genjutsu.

Hun found himself bound to a tree and he started to believe that he was really restrained.

Bloom's treatment was still going on but the Shredder soon made an appearance.

"How are you alive?" Bloom asked

"It takes more than a fall and a water tower to take me down" Shredder said

"What do you want?" Bloom asked

"Revenge against you and those turtles ruining my plans time and time again. You may have defeated me once, but I won't allow that to happen again. I won't stop until all of you are destroyed" Shredder said

The three remaining Turtles tried to attack him, but he proved to just as powerful as ever. He did a spin kick that knocked all of them back.

"We have no choice but to use ninjutsu" Raph said

"But April's shop will be ruined" Donnie said

"Do whatever you can to defeat him. Don't worry about the shop guys" April said

"Alright lets go" Mikey said

Mikey went in first and used his jutsu.

"Lightning style: Thunder wave"

A wave of lightning was hurled at Shredder. But the foot leader laughed at this pathetic attempt. To everyone's shock he performed a jutsu as well.

"Steel style: Metal wall"

A wall of steel appeared in front of Shredder and blocked Mikey's attack.

Bloom was shocked too, she was utterly shocked to see that the Shredder had managed to perform a jutsu too.

Shredder then used another Jutsu and this time he formed a giant sphere made out of wind.

"Wind style: Typhoon Sphere"

Shredder threw it at Mikey and this knocked back against the wall.

"Ok, when did he learn how to do that?" Mikey asked

"I've learned how to use this chakra for myself. Therefore you all are doomed to fall by my hands" Shredder said

Leo's injuries were pretty much healed so she stopped her treatment and charged in to attack Shredder. The shredder's armor turned black and then tried hit her but she dodged his attack in time kicked his stomach and that sent him flying out of the store and onto the streets.

"Nice going now we can finish him off" Raph said

Bloom stopped them from going any further.

"Stop, I'll take care of him myself" Bloom said

"We can't let you face him alone" Mikey said

"Don't worry, I'll be fine" Bloom said as she went after the shredder.

The Shredder got up and was frustrated that even with his new steel style still wasn't enough to defeat the redhead ninja.

Bloom appeared before him and stared him down.

"Well its time for my rematch and this time I will be victorious" Shredder said

"We'll see about that" Bloom said

Shredder then pounded the ground and the street started to break apart. The wave of earth was headed towards Bloom but she managed to dodge it in time. Bloom then used next jutsu.

"Fire Style: Dragon flame bullet"

A giant dragon made out of fire was unleashed on Shredder but this proved to have very little effect on him.

"Is that the best you can do?" Shredder asked with a taunt.

Bloom now understood what the Shredder was using. It was a kekkei genkai.

Shredder then used his new steel jutsu again.

"Steel style: Metal Forest"

A bunch of steel spikes came out of the ground and Bloom was forced to dodge them but this proved to be difficult since they were popping all over the place. But she somehow managed to avoid his attack but her relief was short lived because Shredder started his next jutsu.

"Earth Style: Mud needle forest"

Stone spikes started to grow and the redhead started to dodge them again. This proved to be difficult too because she barely had any room to dodge. Both the metal and mud needles started to unleash senbon on her and unfortunately she was hit by them but she managed to use her chakra to push the senbon out of her body.

The forests then extended some spikes from their sides and Bloom got caught up in it again. Her body got scratched up multiple times.

"You're no match for me now, brat" Shredder said

Bloom used her strength and punched the metal and mud spikes. They broke apart after a couple of hits.

"Impressive strength. It's too bad you aren't on my side" Shredder said

"I would never join someone like you" Bloom said

"Yes…I'm well aware of that. Originally, I wanted you alive so I could take the power that you possess and now that I have it, I have no more use for you" Shredder said

Shredder then sent a lightning bolt at her and she dodged it. Shredder then jumped off one of the metal spikes he made and kicked Bloom down. The kunoichi managed to get up slowly and realized that he had gotten so much stronger than last time. She hasn't this difficult of a fight since she faced Ogron of the sound four.

Bloom made a decision to fight back with even more deadly force. Her mouth started to fill up with something and this caught Shredder's attention.

"What are you up to this time?" Shredder asked

"Lava Style: Lava spit"

Bloom spat out some lava. Shredder was shocked and jumped out of the way in time.

"What is this? Lava?!" Shredder asked out loud

"That's exactly what it is" Bloom said

Bloom then used another jutsu.

"Ninja art: Acid spit"

Bloom spit out some green fluid and forced Shredder to dodge her attack by jumping out of the way but that's what the kunoichi wanted him to do. She jumped up and dived down towards him with her fist ready to punch him.

Shredder formed a black shield to defend against her attack and he was partially successful. His shield managed to absorb some of the blow but the redhead's pure strength pushed knocked Shredder back down to the ground. Shredder got up and charged at her again.

He tried to hit her with his claw but dodged it in time. She jumped to the side to dodge a haymaker. The shredder hit her midsection with an open palm and that knocked her back several feet.

The redhead then detected that the remaining metal spikes started head towards her but she dodged it with a backflip. Another came after her and punctured her shoulder, causing her to scream.

The turtles heard her scream and tried to rescue her but the foot ninja proved to be enough of a distraction for them.

Bloom took the spike out and gasped. The shredder then unleashed something she never thought she would see again. There was black particles in the air and they were slowly forming into weapons like swords and spears.

"That look on your face is satisfying to see" Shredder said

"That can't be. You got iron sand?" Bloom asked in shock

"Ah so you know about this ability already. Too bad it'll be the last familiar thing you'll ever see" Shredder said

The iron sand then headed towards Bloom but she managed to dodge it in time but the weapons changed their direction and went up towards her and sliced her up and a triangle of iron sand smashed her down to the ground, causing a crater.

Leo soon woke up and sat up. He realized that his injuries were healed.

"Leo, thank goodness your awake" April said

"What happened?" Leo asked

"Bloom healed your wounds and your brothers are fending against the foot" April said

"And what about Bloom? Where is she?" Leo asked

April looked away before looking back at her.

"She's fighting Shredder" April said

Leo was shocked to hear that his friend was taking on the Shredder.

"We need to help her" Leo said

Leo's brothers saw that he was ok and they had just finished off the regular foot but the rest of them were difficult and they were knocked out of the store. Everyone else went outside in time to see that Bloom being crushed by Shredder's iron sand.

"NO!" They all yelled

Shredder laughed in victory and then looked at the turtles.

"Do not worry little ninjas, you'll be joining her soon" Shredder said

However Shredder's victory was short lived because the iron sanded triangle started to lift up on its own, much to Shredder's shock. Bloom was lifting up the giant iron sand and threw it at her foe but he dodged it in time.

Everyone could now see how much more deadly Shredder was compared to last time. Just by looking at their friend. She had multiple cuts and puncture wounds on her body. She was bleeding pretty badly and the wounds were deep too.

"We need to help her" Leo said

"I'm sure we can think of something to defeat him we just need to put our heads together" Donnie said

"But she'll be goner from blood loss by the time we think of something" Mikey said

Bloom knew that she would die if she didn't heal her wounds so she had no other choice but to use her ultimate healing jutsu. She formed some hand signs to use it. Master Splinter saw this and asked her to stop.

"Stop! If you fight anymore then you'll be done for" Splinter said

"Ninja art: Creation rebirth. 100 healing jutsu release"

Everyone saw that the diamond on her forehead started to glow pink and the black marks started spreads throughout her whole body.

"I don't know what that is, but it doesn't matter because this battle is over" Shredder said

To everyone's shock, the wounds that Bloom had sustained started to heal on their own. She open wounds started to close and this also stopped the bleeding.

"What is this?!" Shredder asked in anger

"Um…Donnie, you're the medic, care to explain?" Leo asked

"I don't know what this is. She never taught me something like this" Donnie said

"I thought that green diamond was just a tattoo" Mikey said

Bloom faced the shredder again and was ready to fight again. She rushed towards him with great speed and punched him across the battlefield they were on AKA the street.

Shredder got back up and growled. He unleashed another steel spike that was faster and it erupted out of the ground and punctured Bloom's heart in an instant.

"NO!" Splinter shouted

Shredder walked back over to the where he was standing before he was punched away by his adversary.

"Its over" Shredder said

However to Shredder's shock, Bloom was still alive. She punched the metal spike and broke it. She ripped out the spike.

"Don't rip it out!" Donnie said

To everyone's shock however, Bloom's chest wound started to close by itself.

"You should be dead by now. Why are you still alive?!" Shredder asked loudly

"The 100 healing jutsu. This jutsu gives me the ability to stimulate my cells and increases the amount of time cells need to divide and create new ones. Damaged organs and tissues are healed instantly. You can stab me or slice me apart all you want. As long as this is active I can't be killed" Bloom explained

Shredder growled. He never thought his opponent would have something like this up her sleeve.

"We need to retreat at once" Splinter said

Bloom nodded and had everyone go back into store and went into the storage room. The shredder locked them in there and started a fire before disappearing. Luckily the turtles were able to escape in time, but Bloom got caught up in some of the explosion. Everyone was worried because they saw that she just got severe burns on her body. Luckily her 100 healing jutsu was still active so the burns were instantly healed.

All of them managed to escape undetected and fled to a farm house nearby.
