Nero Sparda

Nero is the protagonist of the fourth installment of the saga, along with Dante. Two different essences can be seen in Nero: most of his body is human, but his right arm retains the shape of a claw. It is understood through the metamorphosis that Nero undergoes when facing Agnus, that his arm encloses (or could enclose) the spirit of the defeated Nelo Angelo, that is, the essence of Vergil. More reasons make this fact true, because as the adventure progresses the arm becomes more powerful, absorbing objects, etc. Also Under the comments of Berial and Sanctus, who believed that Nero was the reincarnation of Sparda, since Berial reminds him of someone he saw 2000 years ago (Sparda) and Sanctus bows to someone who possesses Sparda's blood.
