Pantheon's name is directly from the Greek word 'Πάνθεον', referring to the collection of gods in ancient Greek mythology.
Pantheon's dance is a reference to the dance from the "Jailhouse Rock" music video. A side-by-side comparison can be seen here.
Pantheon's lore had previously stated that he was of the tribe "Stanpar" (an anagram of "Spartan"). But when Šablóna:Ci was introduced to the game, his lore had been re-written to replace all mentions of his tribe's name "Stanpar" with "Rakkor."
The picture on his Perseus shield resembles the head of Šablóna:Ci (more specifically, the head of her Classic skin). This is most likely an allusion towards reflecting the gaze of Medusa, seeing as both Medusa and Cassiopeia have a Šablóna:Ai.
Cassiopeia is also the name of a queen in Perseus's adventure who disrupts his adventure.
