I personally think that Capcom has scraped Mundus. To tell you the truth, I didn't like him, as much as I liked the story behind his name and the fact that he was second only to Sparda. The battle with him was epic but still I can't like him. His plan was kind of lame, I can't think any way that it could have worked
So I don't/can't see him being the one who influences Nero. From what I remember in the old trailer "this hand was made for sending guys like you back to hell", meaning that he wasn't always partially demon. But his powers and moves don't seem Vergil/Mundus like to me. Actually the only reason I ever thought that he may be possessed by Vergil is because Capcom says that Vergil remains an important character in DMC series and so on..
Probably Nero somehow got Devil's Power to hunt Devils with some kind of ceremony know to the Order, cool if you ask me.
hmmmmmmmm..........it all seems likly but what about the organization he works for? wonder why Dante is killing them?
maybe the are trying to summon demon power to make the stronger maybe thats how Nero got that arm. Plus Nero is apart of Sparda's whole name his middle name i think. plus he looks like them maybe he was the last born and the org. took him to care for him. plus the voices and the sword which resemble spardas sword maybe it belonged to his mother (RED QUEEN)?!!!! does that ring a bell?
What do you mean Sparda's whole name. No one in DMC universe has more than a word for name apart from Enzo.
And Nero isn't a son of Sparda according to Capcom, his looks etc are mainly for continuing the DMC theme - White Hair - Devil's Powers - Swords - Guns - Cool Attitude and so on. Although Capcom did say that he has some kind of relation to Dante - yet another fact that makes people think that he's connected to Vergil.
And what about the name Red Queen?
