Marvel universe explanation

So some of you are pretty confused about other gods and ultron. Yeah, there are several gods that didn't came out yet which is why I decided to introduce them first. After all it is just matter of time. As for Ultron, he is very underwhelming in original aou. He is nerfed so hard even his original purpose was erased. We are talking about a guy who single handedly wiped humankind. Not only that he created every single replicas of Avengers and others super powered beings. So, I decided to tone up him a little . As I said before I won't kill him off like mcu because it is such a waste of material.
