Blue Lightning

After Splinter announces that Leo is now the leader, everything quickly moves downhill. Raph won't speak to Leo, Donnie snarks and pokes and prods at him and Mikey comforts the other two all while avoiding Leo, because apparently, he didn't need help. They all......blamed him. He didn't want this, he'd NEVER wanted this, but now it was his fault?! When he confronts Splinter about it, the old rat just waved him off, saying "You'll get over it Blue, now MOVE, you're blocking the TV!!!" which honestly made Leo realize how much Splinter had done that growing up, and that it probably wasn't okay.

Leo has enough and decides to leave. Que the Battle Nexus, Big Mama, Hueso, and getting to know Villains! What happens when, about two months later, Donnie makes a portal and brings through their alternates, but realizes he needs Leo's help? Chaos!

(I changed up the timeline of Splinter making Leo Leader. Why? Plot Convenience.)
