Pain and Panic

Pain and Panic are two demons who serve Hades in Walt Disney's Hercules. Pain is the rounder and shorter of the two and has a purplish hue and Panic is the slender and taller one with a turquoise-ish hue.

Description
The two are not very intelligent and obey Hades on command, although mostly out of fear rather than loyalty. The two almost never complete their commands successfully however. They both have the ability to shape shift, but they always remain the same color as their original forms and Pain remains plump, as Panic remains thin. The two can also join together to form one creature rather than two separate ones.

Pain
Pain is the cunning one of the duo and is very sly. Unfortunately for him, he is very clumsy and liable to hurt himself. He often ends up in painful situations.

Panic
Panic is twitchy and nervous, and constantly worries about the simplest of situations. He is also very paranoid and likely fears Hades much more than Pain.

Relationship with Hades
The duo seem to resent their master, but do anything he says, mostly out of fear. In the film, they are sent to kill the baby Hercules. They feed him an elixir that will relieve of his godly powers, turning him mortal, however, they fail to feed him the very last drop, preserving his heroic strength. They turn into snakes and attempt to asphyxiate the baby hero, but he manages to use his strength to turn them into rattles and use them as playthings. Having failed, they worry about what punishment their cruel master will bestow upon them and decide not to tell him of their failure. When Hades falls into the river Styx, they hope that he will never return and that they will be able to live their lives free of worry from his punishment.

Kingdom Hearts II
In Kingdom Hearts II, Pain and Panic serve simply as the lackeys of Hades who work at the Underdrome. Sora needs to speak to Panic if he wishes to enter a tournament. They serve as minor characters, and they never utter an audible word in the game.

Pain and Panic have their a cup named after them in the game. It is the first cup unlocked in the Underdrome.
