A Godhood Seeker is, quite plainly, a mortal or otherwise non-divine being who wants to be a god. The most obvious purpose for doing this is the ultimate quest for power — gods tend to be the ultimate authorities and rulers in settings where they exist, making divinity the logical goal for someone driven by ambition and a desire to rule. Likewise, someone concerned with personal rather than political power (such as in the form of magical might, or control over one's environment) may see godhood as the ultimate pinnacle of mastery over reality.
Alternatively, someone may seek godhood in order to bring themselves on the same playing field as preexisting gods. For instance, a character may wish to confront a deity directly, or to unseat one and take their place. Relatedly, a character may feel that the current gods are not doing a good job of running things and believe they could manage the universe more efficiently or fairly than they are.
For successful Godhood Seekers, see Deity of Human Origin. Note that Deities of Human Origin may not necessarily seek godhood before they became divine beings. This may overlap with Transhuman Treachery if becoming a god makes the new divinity look down on their once fellow humans/what have you.
Compare Immortality Seeker, with which this may overlap. An immortality seeker "merely" wishes to live forever, without necessarily wanting other changes in their condition. A Godhood Seeker, by contrast, may only pursue eternal life as a secondary effect of their quest for divinity.
Compare with A God Am I, where a powerful but otherwise normal individual has delusions of already being a god. A Godhood Seeker is generally fully aware of their currently non-divine status.
