Pyrahedron

Pyrahedron is the first caretaker in HOPE. His hero is Gold. Although he is shorter than Cube, he is the oldest and wisest caretaker. He is not related to Pyrare and Barracuda in any way. Pyrahedron is either a Triangular Prism or a square-based Pyramid but he is most likely the second.

Episode appearances
He made his first appearance in episode one, telling Cube and cubical that cube is the fourth caretaker and that he must seal the monster with cyan within one day.
