Apotheon is a metroidvania with a Greek Mythology theme attached to it. It’s notable in the fact that it has an interesting story that was clearly built by people who were fans of Greek Mythology.
The start of the game reveals that the protagonist – Nikandreos – is actually the bastard son of Hera…the only bastard child she has. Her intent was to use him to get revenge on Zeus for his constant womanizing.
While this is a very interesting idea, it’s also out-of-character for Hera to do this due to the fact she’s the Goddess of Marriage and her issue with Zeus’ constant shenanigans was that he wasn’t being a dutiful husband. It would be unusual for her to, y’know, break the vow as well.
Though I wouldn’t necessarily call it morally wrong due to the simple fact the marriage vow is rendered null by Zeus’ everything.
