Well, these two figures recently fought in the Injustice series. I don’t really think that Ganthet could take down Shazam or come very close to Superman, but it’s still fun to watch. In a true fight, I’d give Superman the immense advantage in speed and power. A single punch should be able to break any construct that Ganthet could make. This is the Man of Steel that we’re talking about after all! Superman wins.
