Still Human
8. What you make of your life is up to you. You have all the resources and tools you need. What you do with them is up to you. The choice is yours.
He's always dreamed of being a hero.
Leonardo watched "Space Heroes" religiously, and all his brothers find some entertainment in "Super Robo-Mecha Force Five", but in both shows he finds the ability of the leaders to power through and successfully save the day nothing short of inspiring.
But he's a mutant turtle, and a ninja at that. His sensei, having been human once, has warned him of the dangers of exposure to the humans above; they won't accept them. They'll fear them. They'll do things to them.
April, Casey, Mr. O'Neil, and even Karai are exceptions, but they also prove the rule. They were terrified, too, at first (though Karai did an excellent job of hiding it).
He wants to be a hero. He wants to save innocents wherever he can. He wants to make a difference in this crazy, messed up world they call home.
Leo doesn't care about the recognition. Helping from the shadows is a good a start as any.
He just hopes he's making the right choice.
