Sailor Pluto and her transformation is not shown on screen. She wields the Garnet Rod, a gigantic key which is topped by the Garnet Orb and a heart. The orb is one of three items necessary for Sailor Saturn's awakening and a reference to one of Japan's Imperial Regalia: the jewel. The reason for garnet specifically being associated with Sailor Pluto is probably due to an elaborate pun regarding her underworld-based powers and mythology. The Japanese name for garnet is "pomegranate stone" and pomegranates were the food of the underworld in the Greek myth of Persephone becoming Hades' (aka Pluto's) wife. Therefore
Pluto uses "Sao Diêm Vương", which was derived from the Chinese term 閻王 (Yánwáng), as "minh" is a homophone for the Sino-Vietnamese words for "dark" (冥) and "bright" (明)). Some Indian languages use the name Pluto, but others, such as Hindi, use the name of "Yama", the God of Death in Hindu and Buddhist mythology. Polynesian languages also tend to use the indigenous god of the underworld, as in Māori "Whiro". Once Pluto was found, its faintness and lack of a resolvable disc cast doubt on the idea that it was Lowell's Planet X. Estimates of Pluto's mass were revised downward
