In the God of War Series
A statue of the God of the Dead can be found in the Temple of Zeus in the Jails of Tartarus. In this statue, one can see Hades with his helmet on, and the spikes adorning his body fully detailed. This statue must be destroyed by Kratos on his quest to escape the jails. This same statue can be found in the fourth Challenge of Hades: Crunch Time.
Though they are not statues, several carvings can be found in the chamber that once contained Pandora's Guardian.
In the Hades arena map there is a statue similar to the ones found in God of War. It is overlooking the arena.
Several Statues of Hades exist within the Underworld, most notably the one inside the Palace of Hades, which Kratos breaks open and where the two of them fight. There are several other statues of him within the Underworld, though they also contain the design from the first game and current model.
