Got an idea.
User: Oogie Boogie.
Stand Name: ?THE JITTERBUG?
Ability: Oogie Boogie is able to summon any insect or arachnid in a five mile radius, and is fully in control of them. The Stand itself is also able to bite, punch, and shoot webbing.
Appearance: I was thinking a giant spider, like the size of a goat or something. The two front-most legs would have gloved hands at the end (kind of like Mickey Mouse or Goofy), and it would have a flute, which it plays when summoning or controlling bugs.
Role: Part 5 or 6 minor villain.
