This monster may be based on Kumbhakarna, the Hindu sleeping giant, who shares similar physical attributes.
The Tributed monster requiring 10 Zushin Counters is based on this card's Summoning condition in the anime. In the anime, it required the controller to keep a Level 1 Normal Monster on the field for 10 of their turns.
Though this makes summoning it both easier and harder. Being forced to reveal Zushin in one's hand removes any chance of catching the opponent by surprise, meaning that they can start fighting back immediately, making it harder to summon. On the other hand, if you have more than one copy of Zushin in your hand, you can reduce the amount of turns needed to accumulate sufficient counters by more than half, making it easier to summon.
The Spanish print of this card refers to it using masculine and feminine words in the same line ("Must be Special Summoned [...] and cannot be Special Summoned by other ways"/"Debe ser Invocado de Modo Especial [...] y no puede ser Invocada de Modo Especial de otra forma"). This might occur due to treating it as a monster (a masculine noun in Spanish) as well as a card (a feminine one).
