The next night, the Big Four stood on the rooftop of a building.

"Alright, Anna. I give up. Remind me what are we doing exactly?" Elsa asked.

"I promise mother that I will get this team together again." Anna replied.

"Well, ever since you left, my archery skills and agility training has been hit to extreme big time." Merida smiled.

"That's impressive, little sister." Anna said with a hardcore face as she turned around to face the illuminating city. "Especially when we are up against this Blue Spark and her vigilante drive. But her job will end."

"Hey, no offense, Anna." Elsa said. "But Blue Spark was the only one who will able to fight crime while the rest of us did nothing after your departure."

"And she's so wicked cool, especially her untamed fighting style." Merida grinned.

"Oh please. I'm with Anna in this one." Punzie scoffed. "I mean, have you seen how armed and dangerous that girl acts...?"

The Big Four suddenly heard a loud, unknown noise and rushed off to investigate the sound as they stood on the edge of the building. Another loud roar came from a construction site.

"Looks like someone's cranky tonight." Merida said.

"Hey look!" Punzie said. The Big Four looked up and see the Turtles moving into the construction site.

"It's the Turtles. They must be here to see whatever's in there." Merida says.

"Hey, Leo's back. He's with his brothers again." Punzie said.

"What do we do, Anna?" Elsa asked.

"What we always do. We go and fight. Let's roll." Anna replied.

The Big Four sprang off the building and landed on the rooftop of the warehouse as they started opening up the skylight window and their faces went bewilderment at what they saw.

"Oh my gosh." Merida muttered.

The Big Four watched a whole army of the Foot Clan fighting against a huge arctic monster. The monster was easily beating the Foot Clan. The Big Four gathered together around behind the tall crate.

"This is just sad." Merida said with an amused smile. "The Foot Clan are definitely getting their butts kicked."

"Can't say I agree with you on that." Punzie said.

"So what? I'd rather enjoy the show." Elsa smirked.

"Come on. We have to take this freak down." Anna said firmly.

The Big Four jumped out from the crate and charged forward to attack the creature with their powers. The Turtles noticed them and helped them out. Merida, Elsa, and Punzie went to different direction as they attacked with their weapons. Mikey, Raph, and Donnie went in with their weapons as well.

Anna and Melody went up to help their team against the monster until they saw each other.

"I'll have a some fun with you instead." Melody said with a grin.

Melody began attacking with her sword at Anna, who dodged each swing effortlessly.

"I'm not trying to pick up a fight with you." Anna said as she blocked Melody's sword with her katana. "We wanted to help you."

"Helping isn't my idea of fun, Anna." Melody smirked. She backflipped few feet away from Anna and they both turned around to see Leo fighting Karai.

"We're trying to help you." Leo said.

"Never." Karai said as she back flipped away. She spoke to her ninja clan in Japanese and they retreat.

"Wait! The Shredder's dead! Who are you working for?!" Leo yelled.

Melody looked at Anna one last time before taking off.

"Melody, if Ursula is dead, then who are you working for?" Anna called.

"Hey, Anna! We can really use some help here!" Elsa yelled to Anna.

Anna went back to help her sisters and her mutant friends against the arctic monster. Elsa cartwheeled herself through the air to hit the monster with ice blasts from her hands multiple times.

"Still got some skils." Raph grinned.

"I've been practicing for a long time." Elsa winked.

Merida dashed forward to perform an fire backflipping wide-arced kick at the monster fifteen times.

"Whoo! Nice flame kick, Merida!" Mikey complemented.

"Ok, gotta admit, that was pretty awesome." Merida smiles at Mikey.

Punzie moved forward to perform five spinning kicks from an upside down position and hit the monster with a flying upward drill kick with both her legs and her frying pan.

"Sweet kicks." Donnie said.

"I still do my studying." Punzie smirks at Donnie.

Anna leaped upwards to deliver slashes from her katana at the monster while spinning repeatedly.

"Some surprise you came back." Leo said.

"You didn't tell me you were coming back." Anna said.

"Well, where's the surprise in that?" Leo asked.

Anna gives a slight glare at him.

"I kid. You surprised me." Leo smirks.

"I do love you, leader boy." Anna says as she smiles at him. The two leaders helped their siblings.

But the arctic monster hit the Turtles and the Big Four at once with one punch. Leo, Anna, Donnie, Punzie, Mikey, and Merida were thrown down a couple of floor levels with the monster. Raph and Elsa jumped down at the bottom floor and got their siblings up. The arctic monster backed up the two teams until they stopped against a field of pipes.

"Oh boy." Anna muttered.

"We're dead." Elsa says.

"Okay, anyone else have any bright ideas?" Punzie asked in a panic.

"Just this." Merida replied.

Merida and Punzie hugged each other while screaming at the top of their lungs. Merida started climbing on Punzie, who was still screaming in terror. Mikey looked at Donnie and they both do what Merida and Punzie are doing.

Then suddenly, large pieces of debris hit the two teams. A bright light started to shine from behind the monster, causing it to turn around. The four statue generals started marching their way. One stone general was the leader on the far right, another stone general with a jaguar skin slouch next to him, a female stone general was next to him, and the biggest stone general was carrying a big hammer at the very end of the row. The devices on their stone bodies glowed red. As the four stone generals moved closer to the monster, it started to walk towards them as well. The monster let out a mighty roar and charged forward to attack the biggest general, but he swung his hammer to hit it to the nearby wall. As the monster laid on the floor, the stone generals gathered around the monster to look down upon the creature.

The Big Four and the Turtles immediately rushed over to see the monster is gone.

"What the heck?" Punzie said in confusion.

"How did something big like that just disappear? It doesn't-?" Donnie stuttered.

Then, the two teams heard loud familiar sirens outside the warehouse.

"Oh snap. It's the cops. We gotta go." Merida says to her older sisters and her mutant friends.

The Turtles jumped in the sewers while the Big Four ran across rooftops. Elsa quickly looked back and saw something unusual. She wanted to take a closer look but she caught up with her sisters.
