That's the problem though, when it is said that Almighty powers can do anything it is meant as "anything except for Omnipotence". That is because we basically consider Omnipotence not something that is impossible but something beyond impossible and illogical.

Imagine this: you're writing a story, now you can write any character no matter how ridiculously powerful they may be. But in the end can't you simply retcon the characters to be weak? Yes, you can so, in the end you're the real all-powerful here and no character can come close to you as becoming as powerful as you isn't beyond logical, it is beyond illogical and beyond impossible.

Now, can any character come out of the story and kill you? No, maybe your avatar can die via those 4th wall breaching and Fictional Transcendence but you can never be killed by them as after all they are merely some ink on paper for you. That is exactly what an Omnipotent being is to any other character and that is why no character can become Omnipotent, either you are omnipotent or you're not or are not, similar to how no fictional character can become as powerful as you.
