Similar to the Trickstars, Skye's previous main archetype, the Marincesses are all women dressing in various colorful attires, with the distinction of them dressing similar to royalty and with a secondary design of the various sea creatures being incorporated into the clothing. Due to being created by the Water Ignis, they have a blue or purple tint somewhere around themselves. Their crest or logo is similar to the gem at the center of Marincess Crystal Heart, which could be a reference to the Heart of the Ocean, a necklace from the 1997 Film Titanic which had a blue diamond in the center.
"Marincess" is a portmanteau of "Marine" and "Princess". Their kanji translates a "Sea Gem Maiden", which seem to be more or less, another transliteration of their English name.
