Thank you all so much for reviewing and reading the first story! And thank you for voting for it in the 2017 TMNT Universal Reader's Choice Awards! It got Second Place for "Best Crossover"! And so here's the sequel! :D

This fics takes place after the series finale of TMNT, "Wanted: Bebop and Rocksteady" and is set during the second GOTG movie.

NOTE: There will probably be grammar mistakes which I will fix later.

"Gooooooood morning, New York!" Mikey shouted with glee as he ran out of his bedroom and slid into the living room. Of course his brothers weren't up yet; he always got up at least an hour before the rest of them to make breakfast.

"What's cooking without a little music?" He took out his T-Phone and pulled up his list of downloaded music, pressing "play" to the song "Bohemian Rhapsody" by Queen. As the music began to play, he walked into the kitchen and reached into the fridge for the eggs and milk.

Is this the real life?

Is this just fantasy?

Caught in a landslide

No escape from reality

Open your eyes

Look up to the skies and see

I'm just a poor boy, I need no sympathy

Because I'm easy come, easy go

A little high, little low

Anyway the wind blows, doesn't really matter to me

To me

After setting the eggs and milk down on the counter, he opened the door to the freezer and pulled Ice Cream Kitty out. The dairy feline mewed happily as she licked him on the nose, leaving a pink drop on the tip of his beak.

Mikey giggled and licked her back. "Morning, Kitty!" He put her bowl down on the table and proceeded to making breakfast: French toast.

...

The smell of bread being grilled crept into Leo's bedroom and brought the Turtle out of his sleep. He took a couple of whiffs and a small smile formed on his lips. Mikey was making French toast, his favorite.

Every morning before breakfast, Leo would go to the dojo and kneel before Splinter's shrine, paying his respects to his late father. Sometimes his spirit would appear to give his eldest son wisdom and advice during times of trouble, but it just wasn't the same. He wanted his father here with them physically and all the time, like the good old days. He knew that his brothers felt exactly the same way as he did, and it hurt his heart to see them so forlorn whenever they would talk and mention about their dad.

But out of all his younger brothers, Leo worried about Mikey the most. The youngest of their group was also the most sensitive and emotional, and the tragedy that took their father away perhaps hurt him the most, even more than it did Leo. Of course, Mikey would try to hide his inner most feelings from everyone with a big smile and pretend to be fine, but Leo could see right through his little brother. Even the music that Mikey has been listening to lately betrayed how he really felt, upbeat yet with depressing and dark lyrics.

After spending about ten minutes in the dojo, he headed toward the kitchen and could hear one of Mikey's songs playing, "Jump" by Van Halen.

Ah, might as well jump

(Jump!)

Might as well jump

Go ahead and jump

(Jump!)

Go ahead and jump

Ow, oh, hey you

Who said that?

Baby, how you been?

Leo peeked his head in and saw Mikey humming merrily along as he did the finishing touches on the French toasts, topping them with whipped cream and strawberries. The younger Turtle noticed his brother and smiled at him. "Morning, Leo!" He gestured to the French toast on the table and spoke in a fake French accent, "Breakfast is-a served, Monsignor!"

Leo chuckled and walked into the kitchen. "It's Monsieur, Mikey." He took his seat at the table and looked down at the food before him. On top of his French toast pile, a smiley face shaped with a whipped cream mouth and two stawberry eyes stared back at him. "Well, my breakfast looks rather...happy."

"Happy to see you this morning!" Mikey exclaimed as he squirted whipped cream onto Kitty's head. For some reason, he really liked doing that to her.

The music continued to play on Mikey's phone as they started to eat.

Ah, might as well jump

(Jump!)

Go ahead and jump

Might as well jump

(Jump!)

Go ahead and jump

JUMP!

When it got to the radical guitar solo, Leo lifted his eyes from his food and up at Mikey. The young cook seemed to enjoy his culinary artwork, humming in approval and delight at each bite. Mikey noticed him looking and stopped eating, his mouth still full and his cheeks puffed out like a chipmunk's. "Iz if goof?" he asked muffled.

Leo chuckled softly and nodded. "It is. Thank you, Mikey."

"I thought I heard Van Halen in here."

They both turned to see Raph and Donnie standing at the kitchen doorway. Raph had Chompy on his shoulder, and the little space turtle was nibbling at the ends of his already tattered red mask. Donnie looked like a zombie, as he did every morning after working so many hours in the lab the night before.

"Morning, bros!" Mikey cheerfully greeted them. "Come get your breakfast!"

Raph was the first to reach the table and the first to see Mikey's artwork. He raised an eye ridge at his breakfast and then rolled his eyes. "How original," he mumbled sarcastically. "No offense, Mikey, but I came in here expecting to eat food, not art."

"You can still eat it!" Mikey insisted with a smile. "Mr. Smiley is an added bonus to start the day off with fun and good feelings!"

"...Whatever." Raph took his fork and stabbed it into the pile of toasts. He picked off the strawberries and gave them to Chompy who sat on the table next to his plate.

Donnie took his seat and picked up his fork, but when he saw the strawberries on his food, he picked them off with a displeased look. "Mikey, you know I don't like strawberries."

"Sorry, D," Mikey said sheepishly. "I keep forgetting."

Leo frowned disapprovingly at Raph and Donnie. Couldn't they at least thank Mikey for making breakfast for them? "Guys, be grateful," he said sternly. "Mikey put a lot of effort into this."

Raph growled softly in annoyance. "Yes, Mother."

Mikey flashed Leo a grateful grin and went back to eating. At least one person here appreciated his cooking.

Later that night, Leo paired up Mikey and Raph with Donnie for their usual nighttime patrol. The eldest and the youngest sat at the ledge of a building, keeping watch for ant suspicious activity on the streets below. So far, nothing. It's been extremely boring and uneventful since the Bebop and Rocksteady incident. No supervillains to fight or going on interdimensional travels. All they did lately was play video and board games, go on patrols, and eat snacks and pizza.

At one point, Mikey looked up at the starry sky, reminiscing about their days in space. They visited amazing and strange worlds and made some awesome new friends (and even found romance in Raph's case). Among those friends were the Guardians of the galaxy, a group of nobodies and criminals who, with Mikey's help, defeated the power-mad Ronan the Accuser and prevented him from using the power of the Infinity stone to destroy the galaxy and possibly the universe. They were a strange bunch, but they were the coolest friends Mikey ever had. They were like family, even. A dysfunctional but close family.

Mikey sighed deeply, the twinkling dots in the dark sky reflecting in his sad eyes. He really missed hanging out with the Guardians.

Leo heard his sigh and looked over at him. "Mikey, are you okay?"

Mikey turned his head to where Leo sat and quickly nodded, a forced smile on his face. "Uh-huh. Yeah. Everything's cool."

The older brother raised a skeptical eye ridge. "Are you sure?"

Mikey nodded again. "Totally."

Leo let out a sigh of his own and looked back down at the street. When was Mikey going to be honest with him? It was really frustrating. He had been burdened with the responsibility of being the eldest brother and clan master, but lately he's been feeling like a complete failure. Why did Sensei place so much trust in him?

"Hey, Leo?"

Leo's face brightened up with hope. Was Mikey finally opening up to him? "Yeah, Mikey?"

"What the heck is that?"

"Huh?" He looked at his brother, who was staring and pointing at the sky. He followed Mikey's gaze and his eyes immediately widened. A bright yellow light that shone brighter than the stars was getting larger and larger by the second, like it was heading straight toward them.

Leo's heart skipped a beat when he realized that it was hurling toward them. Was it a meteor or an attack by an unseen force? He quickly grabbed Mikey's arm and pulled him along as he ran to the rooftop closest to theirs. "MIKEY, RUN!"

But before Leo could make a leap onto the next building, Mikey jerked his arm away. "Dude, wait!" The younger Turtle pointed to the mysterious falling object. "Look!"

Although he wanted to make a run for it, Leo stayed where he was and looked closer. He was shocked to see that the "meteor" was actually a ship. A Nova Corps ship to be exact. It slowed down as it got closer to the rooftop and it hovered over them with a loud hum.

"Nova Corps?" Leo scratched his head. "What are they doing here?"

They both stepped back as the ship got to about fifteen feet above the rooftop, and when it finally landed, the front of it opened to reveal a man with short curly brown hair sitting in the pilot seat.

Mikey immediately recognized him and he gasped loudly. "Corpsman Dey?!"

"Uh, actually, it's Denarian Dey now, remember?" He stepped out of the ship and walked over to where the two Turtles stood. He grinned and saluted to Mikey. "It's good to see you again, Michelangelo."

Mikey excitedly saluted back. "Same here, dude! What are you doing here on Earth?"

"I've been sent by Nova Prime to retrieve you."

Mikey's eyes widened and he pointed to himself. "Me?"

Dey nodded. "Well, actually, if you want to get technical, the Guardians were the ones who asked for you."

"They did?!" Mikey's eyes sparkled at the mention of his old friends. "Really?!"

"Hold on," Leo came forward and stood between the two. "What is this about? Why did they send you to pick him up?"

"The Guardians have been assigned a mission that requires fighting an inter-dimensional monster that feeds on the power sources of other planets," Dey explained. "A fairly easy assignment, nothing they can't handle. But they insisted on bringing your brother along."

"Why?"

Dey shrugged. "I dunno. 'Cause they miss him, I guess."

Mikey grinned from ear to ear. "Really? Awww! I'm definitely going!"

Leo looked at him like he was crazy. "Uh, no, you're not."

There was now a mixture of shock and hurt in Mikey's expression. "What?! Why?!"

"Going into space on your own to fight a giant monster?" Leo crossed his arms and shook his head. "No way."

"Awww, come on, Leo!" Mikey whined. "I haven't seen the Guardians in a long time! They're my friends!"

"And I'm your oldest brother and clan master," Leo said sternly. "And I forbid you from going. Besides, you can't expect me to just stay here on Earth and not worry that you'll get eaten or blown up."

Mikey thought about this for a moment, then the light bulb turned on. "I got it! You could come with me!" he said with a big grin.

Leo blinked. "I-I...what?"

Mikey eagerly nodded. "Yeah! You go to space with us so that you can keep an eye on me and not have to worry!"

"Mikey, I...I can't just leave Raph and Donnie-"

"Sure you can!" They both turned around to see their brothers standing at the other end of the building. Raph grinned as he stepped forward. "Donnie and I can take care of things while you're gone!"

"When did you guys get here?" Leo asked them.

"A couple of minutes ago," Donnie said and pointed to Dey's ship. "We saw the ship and followed it here. Raph's right, we can handle it. It's not like we'd be completely helpless with you."

"Yeah," Raph nodded in agreement. "I'm actually offended that you don't trust us."

"Guys, it's not that I don't trust you," Leo insisted. "It's just-"

"We get it," Raph gave him a smug grin. "You're a worrisome mother hen. But really, we got this. Go on your space trip with Mikey and have fun."

Leo still wasn't convinced. "Look, I hate being the bad guy but I can't-"

Mikey grabbed his shoulders from behind and leaned forward to whisper in his ear, "We could use a Captain Ryan in our group."

Leo's eyes instantly became big and sparkly. Okay, now he was convinced.

They decided to meet Dey again in the park after they had packed up for the trip, bringing with them essentials such as weapons and a First Aid kit, and nonessentials such as comic books and other stuff that mostly came from Mikey's room. Even on their way back to the ship, Leo continued to lay out the rules to Raph and Donnie, expecting his more responsible and mature younger brothers to follow them while he was gone.

"And don't forget to polish the blades every afternoon. And clean out the fridge of any outdated foods. And don't leave the water running in the sink like you did last time. And don't-"

"LEO!" Mikey impatiently waited in the ship for his eldest brother. He was so ready to go into space again and reunite with his secondary family. He just wished that Leo would hurry up. "Come on! Let's go!"

"Yeah, I'm on a pretty tight schedule here," Dey told him as he pointed to the watch on his wrist. "I ain't got all day, you know."

"Right, sorry!" Leo apologized before turning back to Raph and Donnie. "I'm really counting on you guys to keep things in order while I'm gone."

"You won't be disappointed, Leo," Donnie gently assured him.

"Yeah, now get going already!" Raph roughly but playfully shoved him toward the ship.

Leo picked up his backpack of supplies and hurried to the ship, but before he got in, he turned to give one more look at his brothers, who smiled and waved at him to go. Once everyone was on board, they took off into the night sky at full speed, and Raph and Donnie watched as the golden light of the ship's rocket got smaller until it disappeared.

Raph turned to his immediate younger brother and grinned mischievously. "Party in the sewers?"

Donnie grinned back and nodded as he pulled out his T-phone. "I'll text everyone an invitation."

They laughed and whooped as they gave each other a high-three.

And so the epic story begins! Next chapter, Mikey reunites with the Guardians! And meets baby Groot! :)
