lelouch vs yagami who would win

both 2 guys at their mental peak to me it souds like a great story one has the deatnote and the other geass altoug both have limitations in the right hands those powers could becom pretty scary weapons

If he knew lelouch's face and real name it would be over as soon as it started, if he did not lelouch would not be so stupid as to show his face and tell him his name

i also think it would be yagami however still its lelouch he is not one to be tricked easely plus he plans out the course of every event almost always whitout fail

Everyone knows him as Zero. So I don't think that light would be able to find him. Plus, if Lelouch reasearches possible suspects and goes around with the Geass in areas where he thinks Light could be found and commands people to "take me to Kira" He'll eventually get a lead.

depends who saw who first XD lelouch if it was just a chance meet :P but.... it takes a few seconds to work so lelouch wood make it so hed kill kira even after he dies (he being lelouch) so......theyd both win XD (if geass works after death o3o)

i dont know man i do admit that lelouch has a beter weapon (geass) but in the end it would still be a battle of wits the only factor that would be unpredictable would be who got better luck at least that's what i think :P
