I Don't Like the Gods, I Want to Be a Hero

For some reason, a tiny baby appeared in the River Styx in Greece. Out of pity, Hades, the god of the underworld, saved the baby. He named his adopted son "Seleucus" and sent him to the wise man Chiron to learn martial arts.

Hades invested a lot of affection in this adopted son, and Seleucus lived up to everyone's expectations and soon grew into a hero that even the gods took notice of.

Hades was proud of his son, but as Serius grew up, he gradually became troubled by his son's excellence. As for the reason:

Zeus: "My child, have you made up your mind today to become his heir?"

Ra: "Seleucus Ra, you are the brightest sun in the sky."

Odin: "Thor and Balder are both my sons, and as their brother, Seleucus is naturally my son too."

Hades: "..."

So, can you three shameless bastards please get away from me?
