I already know of dr manhattan, just read Divinity from Valiant and really enjoyed it's take on a human -> godlike being. Specifically where they have and exert power over reality, rather than just having more energy to pew at a higher scale.

I always find godlike stories more intresting when it isn't just them fighting at a grander scale and they actually use godlike powers to manipulate reality. Also when they start off as humans, arent born gods and haven't already existed forever.
