The one with a frozen heart

A/N: Okay, here is my new story, which is a sequel to 'The winter storm of my brother's heart.' And I know you've probably already read about the info in the A/N of the last chapter of 'Mutagen Madness' but if you haven't I'll tell you shortly.

Donnie has grown used to his new powers and is having a great time with his father, brothers and friends. But the drama is not over yet as April and Casey are growing closer and closer and more enemies are crawling around in the city. And the Shredder is determined to get Donnie's powers on his side. No matter the cost.

The story will be a 'musical fanfiction' like the last one, but since there is no Frozen 2 I will choose the songs myself, both normal songs and musical songs if they fit with the story. And if you have any suggestions, don't be afraid to tell me why you want them and if they can fit in. I'm always open to suggestions to make my stories better. And hope you don't stop reading my story but Alex will not be in this story. Not so much anyway, sorry but can't find any good place for him. But I don't think you will be that upset, but if you'll be, I'm sorry. Hope you enjoy the first chapter of 'The one with a frozen heart.'

Chapter 1, Brotherly times


(Karai's P.O.V)

Five weeks after 'The big blizzard'

As I walked towards my father's throne room I started to think over what I was supposed to say. When he had come back from Japan he had found his old throne in the trash along with pieces of a broken window. It had been a few weeks since 'the big blizzard' as media called it, and when Father had come back home to New York he had heard about the winter storm in Japan on the news and had, to say the least, a few questions. I entered the room and kneeled down in front of him. He waited as Bradford and Xever entered the room and kneeled down on either side of me. Then he started talking.

"Karai, I heard about a big snow storm here when I was gone. Can you explain how that happened?" I was quiet for two seconds, then took a deep breath and started talking.

"It was those turtles! One of the turtles caused the big winter storm through some kind of mutagen reaction or something. It wasn't my fault! It was his, and the others turtles! It was like some kind of snow power or something. I've seen it myself!" Father didn't say anything at first, but after a minute he gave his response.

"Karai, I have no time for silliness. I want a serious answer." He didn't raise his voice, but sounded annoyed. But I didn't care, it wasn't the first time I had talked back to him.

"But it's true! I swear, he froze us in solid ice and swore to let an eternal winter over the city, but then took it away after a while! I swear it's true, ask Bradford or Xever if you want, they were there!" My father didn't say anything first, but after a while he turned to Bradford.

"Bradford, is what my daughter says true?" Bradford bowed his head in respect as he was being spoken to. When father had asked his question he looked up and gave his answer.

"Yes, Master. She is telling the truth. One of the turtles, Donatello has gained a certain power from the mutagen. He is extremely powerful and managed to defeat most of the foot-bots, me and Xever and Karai on his own!" Father mumbled in thought and then stood up from his throne and spoke again.

"Interesting. Tell me everything you know about this power of his. And I mean everything..."


(Donnie's P.O.V)

"Okay, are you guys ready?" We all were on the top of one big snow mountain and had a great view over the big abandoned train station we were playing in. It had been a few days since we fought both Kraang and the Shredder's forces and we felt a little worn out, so after training today we had all went out into the sewer and found that old abandoned train station a bit away from our lair and my brothers begged me to make it snow and after a bit of convincing I did.

At first we had just done relaxing stuff, like building snowmen, making snow angels and such. But after a while it had broken out in snowball fights and just messing around with the snow, and after about half an hour I made a bunch of snow slides and this was about the highest (at least 15 feet high) and steepest slide so far, and at the bottom it was a ramp so we would fly at the end.

My brothers nodded with smiles on their faces and with that I placed my hand on the snow and a thin layer of ice spread over the snow. And after that we started to slide down in a growing speed. I heard Mikey squeal in delight and the others laughed along with him. And I had to admit I also liked that feeling in stomach as the speed increased and it got steeper and steeper. Mikey had his arms in the air, Raph laid on his stomach and Leo laid on his shell and all three and laughed.

"Look out below!" Leo called out as we flied through the air from the end of the slide and land in the snowdrifts laughing. I admit that hitting the ground made me lose my breath for a minute, but I didn't mind. It wasn't that often we had done these sort of things before 'the big blizzard' happened and now it felt so good to hang out with my brothers. Especially considering that I was locked away from them for a while. We didn't want get up immediately when we all hit the snowdrifts, we stayed on the ground for a while and tried to catch our breaths, which was a challenge since we were laughing the whole time.

"That was awesome!" Raph exclaimed between his panting breaths. Leo nodded while letting out some grunt of agreement and Mikey just got out an m-sound. I looked at my brothers and sat up, dusting the snow of my body smiling at them.

"Well, I'm glad you enjoyed it. I guess my powers has some good use besides freezing things and making blizzards." Leo sat up beside me and placed a hand on my shoulder and smiled at me.

"Of course they have. Your powers are beautiful, and are useful in more than one way." Mikey bounced up and threw his arms around my shoulders from behind.

"Yeah! And you are like, immune to cold and winter storms! You're like some kinda superhero, dude!" The rest of us laughed at Mikey's silliness and I playfully pushed him in the face and he, dramatically fell back into the snow face first. Raph had also sat up and moved over to us, and gave me a light punch on the arm.

"And you can also kick serious butt with those powers! You, my dear brother, are awesome!" I grinned sheepishly at my brothers comments and I felt a blush creep onto my cheeks. But I pretended like I didn't notice.

"Yeah, but you know that Master Splinter told me to only use them in a battle when it's absolutely necessary." Raph waved with his hand dismissively and smiled while he did.

"Yeah, yeah I know. But still, you know that you are a pretty darn good fighter!" I felt myself blush harder and then looked back at him with a raised eyebrow and a smug smile.

"Do I hear you say that I am a better fighter than you?" Raph was a little taken back by my words, but then, so fast I didn't quite catch on to what happened, he scooped up some snow and squeezed it into a snowball and threw it into my face.

"Uh, I don't think you're quite as good as me, brainiac! But you can always dream on if it makes you feel better." I didn't answer first, I just tried to cough and splutter out the snow from my nose and mouth. But as I finally got the snow from my mouth I laughed and tried to look threatening.

"Oh-ho. You just made a big mistake dear brother." And with that I made one big snowball and threatened to throw it at Raph. He saw that I was just playing, but decided to play along and pretended to look scared and ran away from me and my snowball. But then Mikey threw a snowball and it hit me in the shoulder and I got so shocked I dropped the giant snowball on myself.

The others started to laugh loudly as I clawed the snow from my eyes and spat out the snow from my mouth. The shock had worn off as I brushed off the snow, so I started my revenge. I stepped on the ground and the snow froze in a second and the others started to slip and fall over and over. I wasn't bothered by cold or snow and not even ice was a problem for me. I made my move and formed new snowballs in my hands and as they was distracted by trying to stand without falling I shot he snow at them. And they all got one in the face and fell again. And then I created a new big snowball and let it fall over them and they all let out shrieks as the cold, wet snow fell over them.

"Donnie!" Leo called out and brushed the snow from his head and shoulders and looked a little disapproving. "Mikey and Raph I can understand, but what did I do? I am innocent!" I laughed at my older brother and walked over to them and helped them up.

"Well, that's what happens when you think you can beat the Snow king, big brother. And then everyone around get's involved, innocent or not. You should know that by now." Leo rolled his eyes with a small smile and accepted my hand, and I pulled him up to his feet.

"Yeah, Considering how you almost doomed America and us in that snow storm, I suppose I should know that." I looked away and felt that guilt come back . The blizzard I had unintentionally created a few weeks earlier and what my ice powers had turned me into was not really a pleasant memory.

"I thought we agreed on to never speak about that again!" I didn't mean to sound harsh, but I really didn't like to talk about that subject. Leo saw that and placed a hand on my shoulder, making me look back at him.

"Hey, it's okay. The winter storm is gone and everything is alright. Right?" He smiled at me and squeezed my shoulder reassuringly. I smiled at him then frowned as I saw them shiver a little. Mikey hugged himself as he shivered. Raph was blowing hot air into his hands and rubbing them together and Leo rubbed his arms. I slapped myself on my forehead and silently cursed myself for my stupidity. My brothers weren't immune to cold like me, and here I went and dropped the cold snow on their heads like a complete idiot! I quickly got rid of the snow and walked over to Mikey and rubbed his arms, trying to warm him up a little.

"Maybe we should go back to the lair and get you guys warmed up?" I said and looked at them with a small frown on my face. The others nodded and we pretty much ran back to the lair.


(Leo's P.O.V)

Master Splinter was in the dojo meditating when came back ,wet and cold so we knew we shouldn't disturb him. But Donnie went into our rooms and got our blankets and made tea to help us get warmer, so it wasn't a problem. I knew that neither Mikey or Raph were much into drinking tea, at least not as much as me and Master Splinter, but they didn't complain. We all sat on the couch and three of us were feeling warmer than about ten minutes earlier.

"How are you guys feeling? I'm sorry, I keep forgetting that you guys aren't immune to cold like I am." Donnie looked a little concerned, and almost worried. And who could blame him, we all knew that cold was a bad thing for turtles and other cold-blooded creatures. But before we had gone out into the sewers we didn't want to bring any warm clothes so we kinda had ourselves to blame.

"We're fine, bro. You don't need to worry about us, it's no big deal." Raph said and sipped a little on the tea, grimaced and with a lot effort he swallowed it and grimaced again. Donnie didn't exactly look convinced.

"Yes it is, it was irresponsible of me to use my powers like that on you! I didn't think it through." Mikey looked at him and smiled slightly.

"But we were the ones that wanted you to use your powers, you were the one that didn't want to use them. It's just karma or something." I shook my head with a smile and rolled my eyes at Mikey's words of karma, but he was trying, which is good enough. Even Donnie was smiling at Mikey's words.

"I'm not so sure that karma has so much to do with that, but I get the point." He said with a small laugh. Mikey shrugged with a smile and pulled his blanket tighter around himself. Donnie seemed to think something over and smiled a little wider.

"But at least I know something good that came from 'The big blizzard' except the obvious reasons." We looked at each other and then back our smart brother who looked at us with a raised eyebrow and a smug smile.

"Like what?" Raph asked and looked confused and raised an eyebrow and looked from side to side. Donnie shifted so he sat closer to us and put a hand Mikey's shoulder.

"Well, think about it. When was the last time that we went out like this in the sewers and goofed off, all of us." He looked at us all before continuing. "I'll tell you when, when we were little kids. I guess we've been hanging out a bit together in the present, but not like back then. We've grown closer, and I don't know about you guys, but I kind of like it." I couldn't help but smile and put my arm around Mikey's shoulders and placed my hand on Donnie's shoulder.

"I like it too. It does feel good to do fun things like this together again." Mikey smiled too and placed both of his arms around us and nuzzled his face in the crook of Donnie's neck. Raph smiled too and moved closer and placed his hand around me.

"Well, for being a bunch of dorks, you're pretty cool to hang out with." He said with a teasing smile. We all smiled and shared a group hug, but what no one of us noticed was that Splinter stood and watched us from the dojo with a warm smile.


A/N: And that's the first chapter. Hope you've enjoyed it and will keep reading this story. And I will try to update this more often than with 'Mutagen Madness' and now there are not that many tests in school and a lot of free days so I'll try to update as often as I can. Good night and bye!
