Hades: Zagreus has a bitter relationship with his father Hades, who seems to think of him as lazy, naive, and foolish. The two frequently bicker, and Hades thwarts his escape attempts at every turn. Zagreus's memories of his father's treatment of him spur him on at the beginning of his escape attempts.
What was Hades worst thing?
Bad things Hades did: 1. He kidnapped Persephone and forced her to marry him by trickery. (Note that he had Zeus's permission though, so Zeus was just as responsible for this) 2. He trapped Theseus in the underworld for trying to kidnap Persephone, so he's a hypocrite 3.
How old is Zagreus from Hades?
He looks about 20, but that doesn't mean anything for Gods. Dionysius is the only Olympian to experience any time as a child, the rest came into being fully formed.
