Kaiba and Leichter in “Unfinished Business”

[as Leichter destroys his Crush Card trap] It's destroyed! But how?! You have the power to destroy traps?! Now I know what monster you are, Leichter! The only monster I know with the power to destroy trap cards!

Yes! I am Jinzo! And with a monster this powerful as my Deck Master, you don't stand a chance! So prepare to lose your body to me… FOREVER! I've been waiting for this moment for quite some time Mr. Kaiba. For years, I stood by and watched you rise to power, a power that should have been mine! As you stepfather's right hand man, I not only helped you run Kaiba Corp, I helped raise you. And how did you repay me?! By taking away every I worked so hard to gain!

How did I do that, Leichter?!

I was next in line to run the company until you forced your way to the top! I'll never forgive you for that!
