Eerie

Eerie is one of Darkghost's best friends. He is a coward even though he is immune to all kinds of pain including acid and fire.

Darkghost, Eerie and X Jr, were having a race. Darkghost was riding in The Dark Ball, Eerie was riding on the E-Cycle and X Jr turned himself into a wheel. Before the race, The Dark Ball ran out of power and as it could no longer hover, it fell through the ground.

Darkghost was taken prisoner by The Witch. However he was freed by an army of Strongo the Magician, Lightghost, Eerie, X Jr, Laserghost, Virtualghost, Darkerghost and Pinkghost. He was then able to escape.

Darkghost, Eerie and their sisters were having a tour at Baked to a Crisp, the crisp factory. While they were there, Crisp Guy said they could all have a free packet. Darkghost tried some chili crisps. His head then set on fire.

Darkghost, Eerie and X Jr went to a bonfire. The three bonfire night ghosts, Guy Fawkes, Thomas Farryner and Claude Frollo came out of the bonfire. Guy Fawkes and Claude Frollo realized that Thomas Farryner isn't evil. They attempted to kill him but ended up only killing each other as he moved out the way.

It was Christmas. A monster called the Snowterror (who was being controlled by The Puppeteer) suddenly appeared. Darkghost called lots of his friends to come and help him. Together they defeated it.

On Halloween Drunk Ghost, X Jr, the Headmaster, Guy Fawkes and Orange Ghost disappeared in a flash of light. They were found by Darkghost, Eerie and Lightghost and upon their discovery, they got transformed into evil ghosts. The ghosts began to chase Darkghost, Lightghost and Eerie and they eventually escaped. Darkghost managed to trick the others to turn back into their former ghosts but the Zombie-Ghost (Drunk Ghost) didn't fall for the trick. Instead, he agreed with Darkghost that he will tell him where the previous Drunk Ghost is (the Headless Horseghost) then he will stop being evil.
