Suppon no Karon

The Suppon no Karon is a species of Dry Bones in Super Mario-kun that, in the future, evolved to have shapeshifting bones. Only one of them, the Kāmenētā, appears only in volume 5.

In the future, Bowser has lost his title of king, so he hires a famous Suppon no Karon, the Kāmenētā, to go back to the past and kill Mario, before he defeats him in Super Mario World (the moment he considers the beginning of his downfall). The only item capable of destroying a Suppon no Karon is the Super Kōra, which Princess Peach from the future sends to Mario during his fight with the Kāmenētā.
