Tantroni's Japanese name ("Gaki") refers to the Japanese name for preta, or "hungry ghosts". In Buddhism, they are the souls of greedy, gluttonous or otherwise materialistic people who couldn't let go of their desires and thus wallow in the underbelly of the universe, plagued by a constant hunger. In Japanese, spoiled or bratty children are also called "gaki" as an insult.
"Tantroni" combines tantrum and oni. "Gaki" is the same as its origin, but with a katakana syllable replacing the first kanji.
