The Factor Four
Trying to outdo their rivals of the Atom Family, they exposed themselves to mystic artifacts that changed them into elemental beings. They look human-ish, but are entirely comprised of their particular element. Now they strive to profit and manage their forms to enjoy their profits.
Professor Fathom is their leader and the most likely to even come close to fixing their team. He was changed into a being of water.
Sylph fawns over Fathom but is more than willing to use her charms on anyone to get what she wants. She was turned into a airy vaporous form.
Pyre loved danger and fast things, and working for Fathom got him money to do more. He was transformed into a living effigy.
Granite was a simple man who lifted heavy things and moved obstacles out of the way (living or otherwise). He is now made of solid rock.
