@TrueGoddessReincarnation The author referred to it with mentioning "Titanomachy" and "fratricide". Honestly though, fratricide is one of the few good things Zeus did that I can remember, his father was an asshole just like him.
This version of Zeus is pretty fun though. I wonder if him changing with Shiva means that Round 2 will also go to the Gods, he seems pretty shrewd, after all. I also like he hasn't been shown as an electric guy (yet, at least), his lightning bolts were weapons forged by cyclopses, not something he could use naturally.
