I'm afraid it goes much deeper than our rivalry over your mother. The bitter feud between the Hamato and Foot clans lasted centuries. Oroku Saki was the son of the enemy. But he was just a child, so my father gave him shelter. We were raised as brothers, and rivals in all things as brothers are. But that rivalry soon turned bitter when we met Tang Shen- your mother. Jealousy became hatred when Saki learned of his true heritage. He swore vengeance and rebuilt the Foot clan. One night, Oroku Saki struck. The blow that was meant for me struck your mother instead. Shredder blamed me and in his rage, he burned our home to the ground, leaving me to my fate. He took you away from me.
Karai (silently seething): After all this time haven't you wanted revenge?
Welcome to "the Courage Slayer." To save your brothers you'll have to face ninja blades as skilled as your own. Which isn't all that formidable, so I cranked up the speed to a hundred.
So, what's up with the head gear, Princess? Daddy issues?
Karai
I want to rebuild the Foot. Bring back honor to a clan that Shredder poisoned for almost two decades. And when I finish, I'll destroy Oroku Saki and his empire, once and for all.
Now you see the kind of pain and suffering revenge causes.
Karai
I know. I thought I could end this by going after his operations. But it's too much of a risk to go after petty targets, just to spite him. I promise, I will no longer go after Shredder's operations. I'll go after Shredder himself.
You must be proud. You are finally a monster both inside and out.

I want to see you fall, then finally your brainwashing will disappear! And she will remember that it was I who raised her! It was I who made her who she is!! I sacrificed everything for her, out of absolute love!!
Karai
Father is right! Your transformation into a monster is complete!
Did my old student not tell you the story of poor Hattori Tatsu? I was born blind but with an acute sense of hearing. They say it me gave a sixth sense.
Plan blackout was definitely not the way to go, dudes.

Shredder recognized this as a rare ability when all others mocked me. I used that prejudice in my favor until I became Shredder's right-hand: the Blind Swordsman. When this brat recruited Foot soldiers of her own, they attempted to eliminate me.
Splinter once taught me: "Underestimating your enemy is a deadly weakness, but trusting in your allies is a great strength." We're gonna need your help against Hothead.
