What Dante approves of
Pizza - In both the Devil May Cry 3 manga and video game, he is introduced shoving a pizza down his throat. See! Video game character do eat! And Pizza is the only thing we've seem him eat...
Strip Clubs - When he was 18 years old (and maybe hung out their at a younger age) he is often seen in Love Planet -- A strip club.
Rock / Metal - The video games have very heavy (and usually gothic) music. In Devil May Cry 3: Dante's Awakening, he is excited about the guitar like weapon and throws a little rock show singing and dancing. Later uses it to bash enemies around the head with.
His mother - Dante gives the impression that he was very close to his mother and he always wore that pendant. He is avenging her murder at the hands of demons.
Attention - He loves to be the center of attention. He hates it when someone steals his spotlight and argues with them, often forgetting about the threat that stands before him.
Ladies - He flirts with anything in a skirt even if they try and shoot him. He's probably into orgies, as he hasn't really got ONE lady friend. He's paired up with Lady, Lucia and Trish.
Dislikes
No-nos.
Father - At first, he hated his father. After the events of Devil May Cry 3: Dante's Awakening, he learned to respect and admire the devil.
Mundus - Eh, the main hero hates the main villain. Obvious? Yes.
Bigger mouths than his own - He hates it when someone or something talks more than him. He will go as far as threatening them to shut their face.
Demons - ... do I really have to say anything here?
Name calling of his mother - If anyone calls his mother anything negative, he gets psycho.
Turn-ons
Oh, yeah
Brotherly fighting, women who look like his mother.
