You can always make a Shazam knock off. Just file the serial numbers off him. Instead of:
Solomon, Hercules, Atlas, Zeus, Achilles and Mercury
you could have:
Sophia (Gnostic spirit of Wisdom) Polemos (the Greek divine personification or embodiment of war), Alke (the Greek spirit of courage and battle-strength), Nike (Greek spirit of victory) and Kratos (Greek personification of strength and power).
Imagine a Willy Waxer (or totally different name) who turns into SPANK. Or if SPANK isn't what you're looking for there are countless old gods you could use to make up a name. I wouldn't trust Wikipedia for real research but they have lists of names there.
https://en.wikipedia.org/wiki/List_of_war_deities - lists scores of war gods, and they have a list for gods of wisdom, the sea, etc.
Maybe take the concept a bit further with sea gods, which are listed
https://en.wikipedia.org/wiki/List_of_water_deitiesFor example, he taps the power of:
Salacia (Roman goddess of salt water), Leucothea (Greek sea goddess who aided sailors in distress), Amphitritev(sea goddess and consort of Poseidon), Poseidon - becoming a aquaman type hero when he says SLAP
Or he taps the power of:
Poseidon, Achelous (Greek river god), Danu (Celtic Continental Celtic river goddess), Doris (Greek goddess of the sea's bounty), Leucothea (a sea goddess who aided sailors in distress), and Electra (an Oceanid, consort of Thaumas) - becoming aquaman type hero by saying PADDLE.
Any word you can think can be spelled using the names of old gods. Any theme you can think of has a list of "god of - " on wikipedia.
So clone him, file the serial numbers off, and write a story about a clearly ripped off - er - "inspired by" character.
