The turtles and Splinter were shocked to hear that they now possessed the same life force that Bloom has.

"What do you mean we have chakra? That's your thing not ours" Raph said

"Its hard to explain but I know for certain that you have chakra" Bloom said

"But how did this happen?" Leo asked

Donnie thought back to their battle against Shredder last night and remembered one thing that had occurred.

"Leo, do you remember cutting the Shredder's white wire that was wrapped around Bloom?" Donnie asked

"How could I forget? I wanted to save her" Leo said

"Yeah but after that the wire exploded" Mikey said

"I suspect that the explosion energy has something to do with this" Donnie said

Bloom agreed with Donnie on that.

"I agree with Donnie on his hypothesis. The energy blew all of you back but somehow all of you ended up absorbing that energy. The energy was my chakra" Bloom said

"That explains a lot" Mikey said

Bloom noticed that Mikey's ankle was injured and offered to heal it which he accepted.

"Well what are we supposed to do with this chakra now?" Raph asked

Bloom gave them a serious look. The family could tell that it was serious since she was giving them that look.

"It means you need to be careful. If you absorbed my chakra into your body, then that means that you need to be careful to not run out because if your chakra runs out then you'll die" Bloom said

"Its not like we need it to begin with" Mikey said

"If you don't mind, I would like to train you on how to use your new chakra" Bloom said

"What do you mean train us?" Mikey asked

"She is offering to train us on how to use chakra. Since this energy is from her world, we should be able to use the same abilities that she can currently do" Splinter said

"This is a type of ninja training that's on a completely different level compared to what we're used to" Leo said

"I'm game, after all this might make easier to fight off any of those bozos that attacked us before shredder" Raph said

"Raphael, I hope you're not thinking about using this for petty revenge matches" Splinter said

Raph remained silent before saying that he wouldn't do something like that.

The family of five sat down and listened to Bloom's lecture on chakra.

"Chakra is spiritual energy that can be used to weaponize attacks. It can also be used to increase your speed and strength" Bloom started r

Mikey interrupted since he was already getting bored.

"Come on we already know that part. Get to the part were can shoot fire or something like that" Mikey said

Raph smacked him on his head.

"Shut it Bozo" Raph said

"Well Mikey, to tell you the truth you wouldn't be able to do that right now anyway" Bloom said

"What do you mean we can't do that right now?" Mikey asked

"Michelangelo, pay attention to the lecture and quit interrupting" Splinter said

Bloom then cleared her throat before continuing her lecture.

"Well you just received chakra so the next lesson would for all of you to learn how to control it" Bloom said

"Control it?" Leo asked

"Right, its called chakra control and it requires focus" Bloom said

"Well Bro looks like you won't be making it past the focus part" Raph says to Mikey

"Now then I want you to feel the chakra inside of you" Bloom said

Through meditation they focused their focused on feeling their chakra and they eventually managed to find their chakra and were able to feel it naturally.

"I…feel it" Leo said

"So do I and it feels powerful" Raph said

"Good now we can focus on trying out the basic techniques that ninja can use with chakra" Bloom said

"And what would that be, Bloom?" Splinter asked

"Master Splinter seems to be really into this type of stuff" Mikey said

"Well he's very passionate about ninjutsu so learning a different type ninjutsu must excite him" Donnie said

Bloom then began her first lesson on ninjutsu.

"The first lesson is the transformation jutsu. This allows you to change your appearance. This will allow you to transform into anything you desire. You could change into an animal or a human" Bloom said

"How about a demonstration?" Donnie asked

"A demonstration huh? Sure" Bloom said

Bloom used her transformation jutsu and transformed into April. They were shocked to see that this was possible in her world. Bloom then changed back and looked at them.

"Now which one of you would like to go first?" Bloom asked

Splinter decided to go first.

"I will go first" Splinter said

With some focus Splinter actually managed to change his appearance and changed into his beloved Master Yoshi.

Bloom clapped and smiled as Splinter changed back.

"Very good, Master Splinter, that was perfect" Bloom said with smile

"That's our master to ya" Raph said

Leo volunteered next and changed into his father and it was perfect.

"Excellent Leo, that was great" Bloom said

Leo changed back and wondered what other lessons about chakra they will learn.

Raph and Donnie managed to get it perfect too and Mikey was the last one. The goofy turtle then changed into Casey but the appearance was completely different. Casey looked more fat then his usual appearance.

"Uh…I don't think that's quite right" Donnie said

Mikey changed back and was about to sit but was stopped by Bloom.

"Mikey, you need to perfect the transformation or else you can't advance to the next lesson" Bloom said

"Aw come on, I did it right?" Mikey asked

"You transformed yes, but the appearance wasn't correct. If you tried to use this on an infiltration mission, then you would be caught immediately. Now focus more on your chakra and get a perfect transformation" Bloom said

Mikey groaned and kept trying and managed to finally perfect it after many failed attempts.

"You finally got it, great job" Bloom said

"Its about time" Raph said

"Training takes patience my son. Focus is also linked to patience" Splinter said

Bloom then went to the next chakra lesson.

"The next lesson is the substitution jutsu" Bloom said

"Substitution jutsu?" Raph asked

"The substitution jutsu is a jutsu that allows the user to replace their body with something else. Such as wood or stones" Bloom said

Bloom then pointed at Raph for a demonstration.

"Now Raph hit me" Bloom said

Raph was taken aback by Bloom's instruction.

"Hit you?! I don't want to hit you" Raph said

"Don't I'll be fine now hit me" Bloom said

Raph did what he was told and hit the redhead and was knocked on the ground. Bloom's body changed into a puff of smoke and a rock appeared in her place.

"Whoa! Now that's cool" Mikey said

Bloom reappeared from the kitchen and explained how it worked and urged everyone to give it a try. They focused on their substitution jutsu and after a couple of tries they were able to perfect that too.

"Excellent, now we can move on to lesson three which is the clone jutsu" Bloom said

"Clone jutsu? Like making a scientific clone?" Donnie asked

Bloom smiled and shook her head.

"No, not that kind of clone. I'm talking about using chakra to make an exact copy of yourself" Bloom said

Bloom then showed them what that was like and made a clone of herself and then it disappeared.

"That's the clone jutsu" Bloom said

Everyone managed to do it perfectly except Mikey who's clone was limp lifeless.

"What happened?" Mikey asked

Bloom smiled because her brother had the same problem when he was at the academy.

"You pumped in too much chakra. You need to use a balance amount in order to have a perfect replica" Bloom said

Mikey tried again and again. He finally managed to get it.

"With this I'll be a one turtle army" Mikey said

Bloom hated to be the bringer of bad news but she had to tell him about the clone jutsu' weakness.

"I'm afraid that the basic clone jutsu can't be used to overwhelm opponents" Bloom said

"What does that mean?" Raph asked

"Well the truth is that the academy clone jutsu doesn't have any substance therefore the clones you create can't actually damage any opponents" Bloom said

"Then what's the point of clone jutsu if they can't hurt opponents?" Donnie asked

"Clone jutsu are mostly used to confuse your opponents. However, if there is an opponent that is familiar with the clone jutsu then they'll know how to counterattack against it because the clones can't leave imprints or crush things like grass or leaves" Bloom said

"I see, so it is merely used to play a trick on one's mind" Splinter said

"Correct" Bloom said

"So are there any clones jutsu that can hit other opponents?" Raph asked

"Of course, any clone jutsu that are past academy level can hurt other opponents, but we can work on that another time" Bloom said

Bloom then managed to teach them the last basic jutsu which was the body flicker jutsu which they managed to master in no time.

"Alright now we can onto more advanced chakra control lessons" Bloom said

"More advanced?" Leo asked in concern

"Trust me you're ready" Bloom said

Bloom then urged them to follow her at the abandoned subway station.

"Next we'll be focusing on climbing the walls here" Bloom said

"Climbing walls? That's it? Piece of cake" Raph said

"Without using your hands" Bloom said

Everyone remained silent and looked at their teacher like she was crazy.

"Um…I think you lost your marbles because its impossible to climb something without using hands" Mikey said

"Well with chakra you can. Focus chakra on your feet and then use it to stick to the wall like this" Bloom said

Bloom demonstrated what she was talking about by focusing chakra on her feet and climbed the wall with ease. This shocked the turtles and Splinter that this was possible. Bloom took it a step further by going onto the ceiling and staying there, not falling at all and she was still only using her feet.

Bloom then dropped back down to the floor and asked her students to give it a try. Mikey went first and the moment he tried to climb the wall he was sent flying off of the wall and onto the floor with a groan. Leo went over to him to see if he was ok and was relieved when he was brother seemed to be ok.

"What happened? He just flew off the wall" Raph said

"Mikey used too much chakra on his feet and because of that he was sent flying" Bloom said

"Too much chakra?" Leo asked

"Right of you use too much chakra then you'll get sent flying off and if you use too little you'll simply fall off" Bloom said

"This is going to be tough to perfect" Donnie said

"Don't worry, I don't expect you to perfect it in the first try You just need to figure the perfect amount of chakra to use to climb the wall" Bloom said

Everyone tried for days and they finally managed to do it.

"Great job you managed to do it at last" Bloom said with excitement

"It took a little longer than we thought it would" Leo said

"Now follow me for the next the lesson" Bloom said

"More lessons? Come on" Mikey complained

"Move it knuckle it head" Raph said as he pushed his brother

They were now located in a deep part of the sewer where the water was deep.

"Why are we here?" Mikey asked

"The next lesson is walking on water" Bloom said

"Walking on water? Is that even possible" Donnie asked

"With Chakra it is" Bloom said

"So what do we have to do?" Raph asked

"Its actually the same method like the wall climbing exercise you just did. Except its more difficult to master and the more you practice it the better you'll be at it. You'd be walking on water without even noticing. Although you need to emit constant chakra in order to stick to the water's surface" Bloom explained

Bloom then jumped down and landed on the water without sinking.

"Fascinating" Splinter said

"Don't worry about sinking I'll use a water jutsu to save you if you get in trouble" Bloom said

It took them a while but they eventually managed to perfect this technique as well.

"Great well done" Bloom said

Bloom helped them perfect chakra control for a week until she believed it was time for them to go to the next stage of their training.

"Alright all of you have made great progress and now is the time for me to tell you how to use the elements" Bloom said

"Finally, we can learn what you use all the time" Mikey said

"Well the truth is I'm not sure how many elements you'll be able to use but I can help you with any element you might have skill in" Bloom said

Bloom then took some paper out her bag and Leo was curious what the paper was for.

"What are those?" Leo asked

"Duh Leo, She's holding pieces of paper" Mikey said

Raph smacked Mikey's head and told him to shut up.

"Anyway, there are five chakra natures. Fire, Water, Wind, Earth, and Lightning" Bloom said

"But we've seen you use all five of those natures" Donnie said

"That's because I'm capable of using all five, which is a rare trait for shinobi" Bloom said

"Ok so do we pick which nature we want to use?" Raph asked

"I highly doubt its going to be something like that my son" Splinter said

"If you pump your chakra into this paper then it will tell you what chakra nature you specialize in. If its fire then the paper will burn, if its water then paper will get wet, if its earth then the paper will crumble away, if its wind then paper will get cut in half and if its lightning then the paper will crinkle" Bloom said

"You mean we can only get one?" Mikey asked

"No, in time you might be able to gain a second chakra nature. But for now you'll need to settle with one" Bloom said

Bloom then asked the important question.

"Now who wants to go first?" Bloom asked

Donnie decided to go first and put his chakra in the paper. Everyone waited with anticipation and the paper responded to the chakra. Donnie's paper was shown to have been cut in half.

"Congratulations Donatello, you're chakra nature is wind" Bloom said

Donnie looked a little disappointed and Bloom had to ask what was wrong.

"What's wrong? Are you not happy with your chakra nature?" Bloom asked

"I was kinda hoping I would get lightning instead of wind" Donnie said

Bloom placed her hand on his shoulder and to put him at ease.

"Don't Donnie, there's stull a chance that you'll be able to get you can get it" Bloom said

Donnie nodded and went back to sit down.

Bloom waited for the next one to step forward and Raph decided to go next because he couldn't wait anymore. When he put chakra in his paper. His paper crumbled away and Bloom congratulated him.

"Raphael, your chakra nature is earth" Bloom said

"Man and I was hoping for the fire nature" Raph said

"Don't worry there's still a chance that you can get it" Bloom said

Mikey was next and his paper crinkled.

"Michelangelo your nature is lightning" Bloom said

"Man, I wanted wind" Mikey said

"Don't worry, you'll get it" Bloom said

Leo was next and his paper went up in flames.

"Leonardo, your nature is fire" Bloom said

"Fire? I don't know how I feel about having fire as my nature" Leo said

"Don't worry you'll get used to it" Bloom said

Splinter was last and his paper was wet.

"Master Splinter, you're nature is water" Bloom said

"Ah perfect, water was always my favorite of the elements" Splinter said

Bloom then trained them on how to manipulate their chakra nature and they manage to do well and she helped them learn many jutsu. They were able to work on their chakra nature for a month before they were able to get their second chakra nature and it was the ones they wanted. Mikey got wind, Donnie got lightning, Raph got fire and Leo got water. Splinter's second nature ended up being earth.

Splinter and Bloom went searching for food around the sewer and they eventually came across a giant alligator, and it roared at them.

"Be careful and watch yourself Bloom" Splinter said

Splinter meditated and some of his chakra leaked out and this seemed to have affected the gator who looked like it was panicking before knocking itself out by bumping into a wall.

Splinter didn't know what had happened because he didn't even release any jutsu yet. The turtles were nearby and saw this and wondered what had happened.

"Master Splinter, what did you just do?" Leo asked

"I do not know my son" Splinter said

"Bloom you know what happened?" Leo asked

Bloom thought for a moment before responding.

"Master Splinter, it may have been unintentional, but you placed that Alligator under a genjutsu" Bloom said

"Genjutsu?" Raph asked

"Genjutsu is like an illusion that causes no harm to the physical body but it attacks your mind, affecting the five senses of sight, hearing, touch, hearing and taste" Bloom said

"That's incredible Master Splinter" Leo said

"I can train on how to use Genjutsu affectively" Bloom said

Leo was also interested in genjutsu and managed to learn some of them too along with Splinter.

Donnie was working on another device but he stopped to take break. He wanted to help his brothers out more and he was also more of the support with his brothers but he didn't know what else to do and then thought back to what Bloom did to Raph when he was injured and went to ask her for help.

Bloom saw Donnie and wondered what he needed when he came over her.

"How can I help you?" Bloom asked

"That jutsu that you used to heal Raph I was wondering if you could teach me how to do that too?" Donnie asked

Bloom was surprised to hear that Donnie was interested in medical ninjutsu.

"You want to learn to medical ninjutsu?" Bloom asked

"Yeah, I hope you don't mind" Donnie said

"It's not that I don't mind but learning medical ninjutsu requires a great deal of chakra control. It's not easy for those who struggle with chakra control to learn" Bloom said

"I wish to learn medical ninjutsu by any means necessary" Donnie said

"Alright, I'll help but you'll have to work hard and that means stopping with your tinkering until you can learn how to use it effectively" Bloom said

"I understand" Donnie said

Bloom trained Donnie how use medical ninjutsu and he managed to learn the basics of medical ninjutsu.

Bloom was in the subway station looking around. She just wanted to find a spot to relax since she always ended up meeting the purple dragons when she goes above ground. She remembered Donnie working on some crystals he found. She wondered what type of crystals they were.

Bloom then heard some hissing and looked around to see where it was coming from.

"Hello? Anyone there?" Bloom called out

She saw the shadow before it disappeared. She then heard a loud screeching noise and this forced her to cover her ears to block out the sound.

A small part of the ceiling collapsed, and Bloom noticed this too since it was falling straight towards her.

"Yikes" Bloom said before backflipping out of the way.

Bloom returned to the lair to hear the guys discussing about the screech and Donnie talking about how he thinks the crystal was melted by some sort of chemical.

"I suggest you investigate these invents before we are attacked again" Splinter said

"Alright Everyone who wants to go investigate say aye" Leo said

"Aye" Everyone but Mikey said

Mikey ended up saying something else instead.

"Meep" Mikey said with scared tone.

"Close enough" Leo said

"We can't go down there chasing monsters we'll never come back if we do" Mikey said

"And Where did you get that idea from?" Raph asked

"Duh, it always happens in the monster movies" Mikey said

Bloom laughed off his fear.

"Oh Mikey those are just movies" Bloom said with a smile

"You won't be saying that when all get trapped down there and never come back" Mikey said

"Enough blabbering scaredy cat, we're going so get a move on before I have to drag you there" Raph said

The heroes were traveling down the tunnel and they came across a giant hole and Mikey almost let out a scream but Raph covered his mouth.

"Could you not scream at anything for five minutes?" Raph asked with frustration

Bloom and Donnie were examining the hole and Donnie tried to think of what could have made a hole this big. It was around the same size as the previous one

"Something must have burrowed into the wall here" Donnie said

Bloom disagreed though.

"No I don't think so the outer layer here is different compared to the rest of the wall here" Bloom said

"What do you think it is then?" Donnie asked

"I think that something must've used some sort of ability that was able to melt the wall and crawl on through" Bloom said

"You seem to have experience with this type of stuff" Donnie pointed out

"Trust I've been through things kind of like this before" Bloom said

Mikey kept making noise and then sneezed which Raph complained about.

"Geez stop making sound" Raph said

"Geez How am I supposed to stop a…huge grotesque and horrifying monster!" Mikey said

Everyone turned around to see a giant rock monster and they were surprised to see something like this before them.

Their adventure continued but they decided to stop for the night. Bloom undid her ponytail for the night.

The next morning, they were awakened by some roaring. A red monster was pushing a boulder down towards them.

"Look out!" Raph called to his brothers and Bloom.

Bloom woke up first followed by the others. She saw the boulder rolling towards them and they had very little room to get out of the way.

"It was nice knowing you bros" Mikey said

Bloom charged at the boulder and punched it and the boulder was smashed to pieces by her super strength.

"Whew, we're safe" Mikey said

"What a way to wake up" Donnie said

They continued their journey and found a broken bridge.

"Well looks like the bridge is out time to go home" Mikey said

"That won't be problem at all" Bloom said

Bloom then used an earth style jutsu to make a new bridge.

"Earth style: Mobile Core"

A pillar appeared out the rock wall and formed a bridge.

"There we go a new bridge" Bloom said

"Awesome now we can continue moving" Raph said

Mikey groaned because now he was going to have to keep going and then face the monsters that were living down here.

"Everyone look at this giant door it looks like it was broken down from the inside" Donnie said

"That's horrifying!" Mikey said

Leo told his brother to be quiet as they continued.

"Look at this lab, it's a genetics lab they were experimenting with mutation down here" Donnie said

Mikey then accidentally set off an alarm.

"Mikey!" They all said

A forcefield was headed towards them and Raph managed to destroy the shield by hitting the crystal with his sai.

Through a video log it was discovered that the foot were behind these monsters by having "volunteers" with some experimental chemicals that turned them into monsters.

"So this an old hideout that the foot had used before abandoning this place" Raph said

"But why? What were they hoping to accomplish down here?" Leo asked

Bloom thought for a moment and came up with hypothesis of her own.

"Well my best guess is that he was trying to create an army of super solders that would obey his orders but I guess the experiments failed so they all fled this facility" Bloom said

"That sounds about right to me. So the monsters were once people and now they're mindless beasts" Donnie said

They were about to go back to the surface above them when they were confronted by three giant monsters growling and Mikey did his girly scream when he saw them.

The heroes will have to fight their way out of this battle for sure.
