Yes, Nero is Dante and Vergil's half brother by an unknown mother and Sparda.
dante and Nero are not brothers even tho they have the same blood
Nero is the main character you play, he is a reincarnation of Vergil, making him Dante's brother and the son of Sparta. He isn't the "bad guy" and even though you fight Dante, Dante isn't the "bad guy" either. image: http://i199.photobucket.com/albums/aa235/argent_angelo/nero.jpg
Yes, Nero is Vergil's Son. There is a mission in Devil May Cry 4 where Agnus trying to put the broken Yamato back together but he can't. Nero arrives at his lab, and a confrontation between Nero and Agnus occurs as Nero trying to find out what's is all going on. Agnus refuses the tell the answers to Nero and stabs him. Agnus called his guards to take the wounded Nero out but suddenly Nero's arms reflects to the broken Yamato and it was putted back together. Nero become more powerful due to the sword. These all scenario proven that Nero is the only one can fix Yamato, which is a sign that Nero is Vergil's son. The last scenario where Dante and Nero defeated the Sanctus and the false Savior. Nero tried to return the Yamato to Dante but Dante refuses to take it. Dante entrust the Yamato to Nero because it was a worth gift for Nero. He also says it's gotta stay in the family. This proves Nero has some sort of blood link to Dante and Vergil.
Nero is as strong or stronger than Dante in devil may cry 3 since they both took on and defeated an enemy who misused Sparda's power however Dante required Vergil's aid where as Nero required none whether Sanctus was weaker than Arkham or Nero was just stronger than dmc3 Dante hasn't been specified
Dunno how long ago this was posted but No Vergil isn't in DMC4 but his reincarnation: Nero (who is the main character you play, though you play Dante too later on) is in the game.
it has been hinted that Vergil is Nero's father however nothing official has been said yet
Technically yes he does die but I suspect that Nero's Devil Bringer is Vergil's Soul manifested in Nero's arm.
Dante would win. It doesnt matter if Nero has the devil bringer because Dante has to much power.Of course he is the son of Sparda
Nero is actually the main character in devil may cry4. you use Nero for the most of the game but on the half way after holiness and the savior kidnap Nero you use dante for 7 stages out of 20.
Nero is the new character but don't worry Dante's still around
Beat the game as Nero first
Vergil doesn't die in Devil May Cry 3, he just gets sealed in the demon world and fights... the big boss of DMC 1, in fact he's kindof IN DMC1... you know... Nero Angelo.... The Dark Knight....
