American Comics: I’m Warner, the God King, and I Declare War on Asgard

That's too lowbrow. Odin would at most visit the Ancient One on Earth; would he even bother with mortals? Thor is just a prince; he can do whatever he wants. The protagonist is a god-king; is he going to play house?

Your Saint Seiya character design is terrible. The original Eighth Sense was enough to kill a god, and the Ninth, Tenth, and even the power of the universe were beyond that. In terms of power, even in Marvel comics, it's close to the ceiling. And Odin might not even be able to beat a Saint Seiya using the Seventh Sense's light-speed punch as a basic attack. The potential of their Cosmo is incredibly high.

Even if you do marry the witch, you're supposed to be a god-king; if you can't even control a witch, this pantheon is doomed.

Don't you find it jarring to use Chinese names for foreign myths?

The protagonist, as a king, lacks any regal dignity; everything is decided by others, and he passively accepts his fate.

The divine body in Super God isn't nuclear-resistant, is it?

The Twelve Talismans were nerfed too much. In principle, there is no upper limit; the stronger the user, the stronger they become. Xiaoyu can crack a mountain with one punch using the Ox Talisman, which is much stronger than the Hulk in the movie. The Dragon and Rabbit can even travel through time, which is faster than the speed of light.

According to the lore, Asgardians grow stronger with age; an elderly Thor could single-handedly defeat Galactus and Thanos with all six Infinity Stones in the Infinity Gauntlet. Therefore, Odin is ridiculously powerful. The eye Odin uses to exchange knowledge is, according to the lore, actually self-sealing. So, it depends on the author's chosen universe setting. If it's the 616 universe setting, then things will get interesting.

The protagonist's name feels a bit out of place.

It's really awkward to see a god from Western mythology with an Asian name.
