Outrageously Dickish
Superman isn't in the running, simply cuz he isn't self sufficient. Without a yellow sun, he'd be relatively normal. And Captain Marvel as well. Both from outside sources. King Thor is Thor drawing fully from the OdinForce within him. Shazam is a wizard who's = to skyfather and thus King Thor. Silver Surfer is the embodiment of the power cosmic, so he's just below the two above. GL power battery is equal to if not a teeny bit above SS. So it goes from top to bottom
King Thor/Shazam, = Self Sufficent/ Internal
Silver Surfer/Power Battery = self sufficient
Juggernaut /Captain Marvel/Superman = Outside power sources
