• This card's name is a reference to Neptune, the god of freshwater and the sea in Roman religion.
    • "Mermail Abyssalacia" might be this monster's female counterpart, as "Abyssalacia" has a similar appearance as "Mermail Abysstrite", thus they can be considered as the humanoid versions of both the king and the queen of "Mermail". This is further supported as "Abyssalacia" is named after Salacia, a Roman Goddess and the wife of Neptune.
