The sound of shattered glass dripped through to the basement cell of the Elizabeth Police Station. The suburb north of Adelaide was infamous for crime and neglect, and the central police station resembled a bunker. Inside, waiting transport to the Adelaide Remand Centre, was Fabrizio Pucetti who had been unceremoniously apprehended by Adelaide's finest while enjoying his weekly visit to the Countess Parlour. Pucetti had been linked to a string of murders and drug charges. It wasn't looking good.

He looked out of his cell down towards the thick door which separated the holding cells from the upstairs police station and realised the sentry had vanished. The thick door seemed to vibrate. With eyebrows raised, Pucetti watched as the door flew backward down towards his cell, dropping hinges and bolts as it tumbled.

In the doorway stood a gigantic silhouette, and Pucetti's face broke into a knowing grin.

"Grimaldi," he said.

The large man walked without speaking, his bulk shifting from side to side as he moved. Pucetti's smile wavered as the silence struck him. Grimaldi was usually a talkative man, but his eyes seemed darker than normal. Pucetti placed his hands around the bars and looked closer.

"Gregorio? What's the matter, cousin? You've come to get me out of here I hope."

Gregorio Grimaldi stood at the bars, his eyes staring darkly into Pucetti's.

"It is over, Fabrizio," Gregorio said, wrapping his own thick fingers around Pucetti's and the bars. "You have made more mistakes than we can realistically accept, and the Don is not impressed. Personally I think this is overdue."

With a hard yank of his thick arms, Gregorio Grimaldi ripped out the bars, along with Pucetti's arms. The sudden movement caught Pucetti by surprise and he stared with utter horror as Grimaldi threw the bars and his arms away.

"You're dead now," Grimaldi said. And Pucetti fell down bleeding profusely.

Later, Gregorio Grimaldi met with the man's father and explained the situation. Senor Pucetti nodded his head with understanding and shame, and then paid the large enforcer $50,000. Grimaldi folded the money, taking half for himself and half for the Family. Grimaldi dropped the two photographs of Fabrizio on the older man's side table.

He smiled and left, and Senor Pucetti realised, with a dawning sense of dread, that Gregorio Grimaldi was rightly called Grievous: the cold blooded enforcer of the Grimaldi Family.

Gregorio is a proud Italian Australian, having grown up in the small goods business alongside the colourful world of organised crime. His father was a hitman and then an extortionist, so Gregorio was able to learn from him at a very young age. He believes that his family honour is the most important thing in his life, and that any attempts to discredit him or his family is enough to warrant a murderous vendetta.

As one half of the Brothers Grimm, Gregorio presents a very professional air, especially when dealing with Italians; although he is rude and obnoxious in the presence of mainstream Australians and those of Asian descent.

“An eye for an eye, blood for blood.”

Gregorio has uberhuman levels of strength and durability, as well as a variety of enhanced sensory attributes. His strength enables him to lift in excess of 50 tons, and his durability is to such a degree that he never worries about facing police officers and their puny weapons. In addition to his uberhuman abilities, Gregorio has trained in direct and deadly martial arts which complement his enforcer duties.

Gregorio Grimaldi is very tall and broad, and weighs 120kg which is enough to plummet him in any body of water. He has an olive complexion, slightly curly dark hair and darker eyes. As Grievous, he wears a purple and silver-grey costume which accentuates his huge arms and is familiar to those in the Melbourne underworld.
