Not much is known about Dante's past, he was left in the Underworld when he was 6 months old, he was raised by a girl named Siren Grimm, she taught him how to kill and he listened to every word.
Later when The Grimms were assembled he was one of the first to join, he wishes nothing more then to make Siren happy and to do whatever she says.
Later it is known that he is in fact a mortal, who's veins flows the blood of nearly all the gods and goddesses, all mixed together.
He is a Child of All.
However the blood inside him will rot away his humanity and slowly kill him.
Messy blonde hair and pale yellow eyes, he is unaturally pale from spending his life in the Underworld, he has many scars on his arms and back from fighting monsters. He also has weird markings he draws on his arms, these markings allow him to move more silently and double his strength.
He usually wears his black armor but when he doesn't he wears a black hoodie, jeans and boots, he also wears around his neck a silver ring that was found with him when he was found by Siren.
He is courageous but arrogant, he enjoys killing monsters, much more if its for Siren, and he's devoted his life to the Grimms and Siren herself.
He never wonders who his parents are because he doesn't care about them, he focuses on his role in the Grimms and nothing more.
Uses a Celestial Bronze dagger along with a Stygian Iron double edged sword he calls "Medusa" for when the monsters see his blade they are petrified with fear.
