Bio: Ghoulwyrm was an earlier attempt by Echidra to make the ultimate dracopyre. Unfortunately, the alien essences rejected each other and caused his mutation and death. He was brought back to life with necromancy making him both a dracopyre and a dracolich. Ghoulwyrm set out on his own soon afterwards and caused the destruction of several Atlantean colonies. He was sentenced to life petrification and storage in Devil's Tower. He was accidentally released by one of Romanov's goons. After a fight with Matt and company, he escaped Earth on a stolen spaceship.

Ghoulwyrm later followed Draco, Chip, Morph, and Contrinus into the Danny Phantom universe. He attempted to subdue Danny with several chunks of enriched Ectoranium, but was thwarted by Jazz, PlasMorph, and his doppelganger, EctoplasMorph. Before Ghoulwyrm was sucked into the Ghost Zone, he managed to bite Jazz on the neck while EctoplasMorph was wrapped around it.

Inside the Ghost Zone, he gathered together Prince Aragon, Hotep-Ra, and the Fright Knight to work for him. The three ghosts managed to trick Matt and his crew into retrieving the powerful Anarchic Amulet of Aragon for them. Ghoulwyrm had set up base in an area of the Ghost Zone known as Davy Jones' Locker so that the darkness of that region would allow him to reach his full potential.

When Jazz started turning into an Ecto-Werepyre, Danny, his friends, and the experiments confronted Ghoulwyrm to make him cure Jazz. Because of the boost Ghoulwyrm got in Davy Jones' Locker, he was more than a match for Danny until Danny managed to drag them both through a natural portal to Earth. Ghoulwyrm then attempted to have Danny join his side. Failing at that, Ghoulwyrm then tried to possess Danny and use him to take over both Earth and the Ghost Zone. He was again thwarted by Jazz in her new superheroine identity, Jazz Sunset. Because Jazz's half-ghostly nature immunized her from the curse's evil affects and Ghoulwyrm's control, Ghoulwyrm tried to destroy the Fenton siblings. But then the sun came up and greatly weakend Ghoulwyrm. He was then captured in an anti-Ghoulwyrm version of the Fenton Thermos. He swore revenge on Jazz before he was sucked in. He was then imprisoned in Walker's jail in the Ghost Zone. It is uncertain when he will return.

At some point, Ghoulwyrm was released and teamed up with Mantichrome. A fairly large amount of their plots involved the enslavement/destruction of the Lyoko werewolves. During these schemes, Ghoulwyrm learned of the extensive of Megan Roph, NegaMorph's technical niece. He soon developed a grudge against her, especially since she 'ruined' two of his monsters which came to be known as Gary Lesog and Weirdwolf.

When he ran into Matt's crew again, Ghoulwyrm decided he need more minions on his side. He broke both ex-councilor Chang and Bananas B out of prison and became partners with Omnirus.

At a later point, Ghoulwyrm's team arrived in the Gargoyles dimension, where Ghoulwyrm made a pact with Maddoc to destroy the Manhatten Clan for a seat of power in Maddoc's new world order. However, the siege on Castle Wyvern didn't end well, with Ghoulwyrm being humiliated by Puck to the point of turning into his demon form out of pure anger. Mantichrome attempted to pull off a coup that would have resulted in the loss of all sentient life on the planet, which could have included Ghoulwyrm. When Mantichrome's plan was ruined, Ghoulwyrm and his team left that dimension. He later punished Mantichrome for his trechery and bound him with a curse that would kill him if Mantichrome or his minions ever directly killed Ghoulwrym or one of his servants.

Ghoulwyrm is rotten to the core in both senses of the term. He is not above using fear to get what he wants. In fact, he prefers to. He is determined to become the #1 nightmare monster in the universe, by any means neccesary.

Trivia: Ghoulwyrm is described to have foul-smelling breath that smells of dried blood and burnt plasma.

Four of the five primary aliens used to create him are from the Anur Belt in the Null Void: Ectonurite, Loboan, Thep Khufan, and Transylian. His afflifiation with the color purple reflect this heavily.

Ghoulwyrm needs to feed on blood like any other vampire, but not as frequently.

Of all the people he has bitten, only Jazz Fenton has survived with a functional curse. The curse is lessened in malevolence because of it being stabilized with ectoplasm from a friendly ghost.

If there's one thing Ghoulwyrm can't stand, it's to be laughed at. If anything threatened to ruin his reputation, he'd put high priority in getting rid of it. One of the quickest way to make him lose his temper is to mock him.
