As you can see from Mikhail Villareal’s Twitter account, Aquaman conceptual designer Christian Scheurer was going for a trident with much longer points than the one that ultimately appears in the film.
It also has more of a jagged look to it, like it was carved from diamond, with hard edges and sharp angles.
By the looks of things, Aquaman could have gone in a drastically different direction for the titular hero’s weapon.
