Following my other comment from this chapter, I’d like to weigh in and say that I find it interesting, that if you go onto their wiki and read the desc. of the Gods, their attributes seem to relate to our respective heroes and their flaws. This makes me think that if Mordret is one of the reincarnations and he is the reincarnation of Heart God. My prediction for his flaw: would have to do with emotion (such as fear maybe). Perhaps a problem can occur if someone is not afraid of him (which might be why he tries so hard to be this scary person in our two encounters with him [the monster in the mist during the Hope Arc or him trying to be terrifying in his prison by randomly murdering] or maybe he has issues if he gets too emotional. This can also have to do with mirrors, maybe our perception of the reflection we see of it (ie Mordret) is what gives the reflection impact over someone.
After reading some wiki, I have stuff to add to my theories :). My guesses about the characters respective hero/God match up. Sunny-Shadow God-Slayer Nephis- Sun God- Lord Cassie- Storm God- Priestess Effie- Beast God- Hunter These last two were more difficult, so not entirely certain: Kai-War God- Builder; or Heart God- Knight (leaning to heart God, because of his voice ability), tho he might not actually be one of 7, not too sure yet Mordret- War God- Builder; or Heart God- Knight. He is hard cuz his background makes me think of War God, but his powers seem to do more with the soul (ie Heart God) Also another big theory I’ve come up. Wiki says there’s only 6 gods, but I believe there is a seventh. Rain/Morgan/Stone Saint- Dream God- Stranger (no one remembers their dream after they wake up, just like no one would remember a stranger).
