"You know all those complaints that people have about Kira/Light vs Lelouch/Zero?"

"You mean that Light needs to know his victim's true name, which Lelouch isn't going to be stupid enough to give to him? And even if he was stupid enough to give his real name, Light gets killed before he can pick up the pen to write down how and when his victim dies? And the fact that Light isn't, never was, and will never be a fighter, making him ineligible for Death Battle in the first place?"

"Exactly! Well, I have the perfect way to fix these problems. Presenting... Light vs Walter White!"

"Uh... Exactly what problems is this fixing when Light's still not a fighter, Walter goes around under a pseudonym all the time, and Walter can just shoot him before Light can pick up his book?"
