If the battle is Lucy jumping Light where neither party has time to prep, Lucy wins. If the battle is scheduled to happen in the future at a location that both are aware of, I think Light wins. Light will never fight her in a one vs. one fist fight. If that's the rules of the battle, then he will break them. Misa, Mikami, Misa's Shinigami, the reporter... Light will manipulate some of them into playing key roles that will get him the name or "inadvertently" put Misa in a situation where her Shinigami has to save her and kills Lucy.
@sickVisionz: Yeah but before that Lucy mutilates Light. Even if Light has luck and has time to prepare he isn't safe. Also Rem couldn't save Misa from Lucy. She would be dead before the shinigami reacts. So as long as Light doesn't know Lucy's name she's sure to win. I think we should lock this thread.
All Light needs is to stay alive for 40 seconds. He can bring out cannon fodder swat teams to occupy Lucy for a few seconds while Misa or Mikami writes her name. As soon as she shows up, the clock is ticking. And that's assuming he didn't figure out her name by manipulating someone at the research lab or Kota.
@sickVisionz: Kota doesn't know lucy real name (Kaede) lucy had three name , Death note actually never shown to actually work where all those name is real, lucy kills swat team in seconds, 40 seconds is too long for them to hold out
@battleheiz: I doubt it would work though. That kind of method only protect you against a Deathnote like L used something similar in the Movie. It has no effect on cases when someone directly tries to kill you.
Lucy doesn't have 3 real names. Lucy and Nyuu aren't anymore legit than L, which didn't work.
The writing your own name in a Death Note would probably work considering that there would be two other people with Shinigami eyes there and Lucy only has 40 seconds. Something could easily pop up for Lights favor. Plus, Lucy likes to toy with people before killing them. Especially arrogant people.
If Misa is there and tries to run out to protect Light, Lucy will definitely focus on her since she seems to get her rocks off by killing loved ones in front of other people. Rem will not let Misa die and would gladly sacrifice her life and do an instakill on Lucy.
@sickVisionz: Forced.Too many speculations about something we have no idea of. Also Light never had a situation where someone tried to kill him face to face...Well, he had one but he failed and died soon after. Light has no chance, period.
For the Death Note to work, one needs the real name (both first and last) of their target to kill them. Seeing as there was no last name given to Lucy's real name and the fact Light wouldn't know anything about her, he's screwed in this match.
