Rottmnt meets tmnt 2k12

explanation plaese!

The kunai floated in midair, surrounded by a faint orange glow.
"What the-!" the kuniochi started, before orange chains burst from the ground and wrapped around her and the two mutants.
They all floated up into the air, before Mikey flung them away, towards the harbor.
He watched the as the flew threw the air. But when he turned towards the turtles, he came face to face with with the red banded ninja.
"What the heck was that!?" He screamed in his face.
"Heycalm down Raph, let him explain." The other Leo pulled his brother back with slight difficulty.
"Okay, to start off with, im from another world." R.Mikey looked at the other turtles blank faces. "My real name is Michelangelo Hamato. The same as you." He gestured towards the other Mikey. "I fell though a portal to this world and got separated from my brothers."
"Let me stop you there." The other Raph put up his hand. "Why should we believe you you have no-"
"Mikey!" R.Mikey turned and saw his big brother run up to him.
Raph grabbed Mikey and gave him a huge hug, lifting him off the ground and spun him in a circle.
"-proof?" 12.Raph finished.
"I have more proof were that came from!" R.Mikey said. As soon as he was placed on the ground again, he deactivated his cloaking broach and he was back to looking like regular old Mikey, still wearing his cloak and baggy clothes he had on under it, but his skin had turned a noticeable green. "Is this enough proof for you?"
"Mikey? Who are they?" R.Raph gestured towards the other turtles as he deactivated his own cloaking broach.
"I'll explain once the disaster twins get here." R.Mikey patted his brothers hand affectionately.
"...twins?" The other Leo gave his Donnie an odd glance.
"Yeah." R.Raph crossed his arms. "Leo and Donnie. They aren't really twins but their both sixteen and Leo really wanted to say that."
"Sixteen? Then how old are you two?" The other Mikey gestured towards R.Mikey and Raph.
"I'm fifteen, and he's seventeen." R.Mikey pointed towards himself, then his brother.
They went on like this for a few more minutes before Mikey heard footsteps behind him.
"Mikey!" Leo was running up the street with Donnie close behind him. The ninja in blue wrapped his little brother in a furious bear hug, much like the one he had given him after they reunited after being separated during their attempted rescue for Raph.
Donnie stopped next to him and simply patted him on the shoulder.
"Could you please explain!?" The other Raph gestured towards the rise brothers.
"Sure, but we should head somewhere else, it looks like the sun's rising and I'm guessing you guys don't have cloaking broaches." Mikey gestured towards the sky and then the other brothers.
"We can take you back to our lair. Then you can explain everything." The other Leo was holding his red brother back again. "Raph  go get the stealth bike back and meet back up with us at base, everyone else get in the shell raiser."
