Wrecking Ball was once a small larval worm poised to become the main ingredient in an old wizard's cauldron of magical stew.
But when it was dropped, the sorcerer was shocked to see the little larva devour all the soup and come out of the cauldron 20 times bigger and with a long sticky tongue.
The poor old wizard was even more surprised a few seconds later, when Wrecking Ball began to swallow him whole.
Eventually, he literally stumbled upon the powerful portal master Eon, intrigued by how he was born and impressed by his unique abilities.
