If a God type being really existed, what do you suppose it would be like?

If you are agnostic, or atheist, tell me what you think a God type being would be like if one actually did exist.
______

If you’re not religious, but are still a theist, tell me what you believe a God being would be like.
______

If you’re religious, and you like the God of your religion, then please tell me about it.

NOTE: I’m more concerned with what you think it would really be like if reality, rather than what you want it to be like in your fantasy. Though you can share your fantasy god too.
