- This card has two upgraded versions, "Neo-Parshath, the Sky Paladin" and "Sacred Arch-Airknight Parshath", a DARK counterpart, "Darknight Parshath", a Synchro counterpart, "Avenging Knight Parshath" and a Link counterpart "Celestial Knightlord Parshath".
- This card is the opposite of "Mefist the Infernal General" in a number of ways. This monster is a LIGHT Fairy and Mefist is a DARK Fiend. While both monsters have the Pierce effect, when they inflict damage, this card allows you to draw 1 card while "Mefist" forces your opponent to discard. However, "Mefist" does not have a upgraded version of itself while this card has.
- This card is named after the mythological character Perseus, but the name was mistranslated (Pa-Shi-Ah-Su).
- This card is the one of the few cards to not have its halo removed in editing, another being "Belial - Marquis of Darkness".
- Its appearance in the anime has its shield mistakenly drawn upside-down.
