*The Ranborg are the main monsters from "Hirogaru Sky! Pretty Cure" that first appear in episode 1. They are summoned by the generals of Undergu Empire, using the power of Undergu Energy by saying the phrase, C'mon! Undergu Energy.

They say "I've been purified~" when they are purified by the Cures.

The Ranborgs are voiced by Souma Kouichi.*

RANBORG!!!!!!
