Blitzo/History

Past
Blitzo was born to Cash Buckzo and an unnamed female imp, alongside his twin sister named Barbie Wire. Growing up, he worked in the family's circus ran by his father and ringleader. Blitzo's father had gotten Blitzo to do something which the young boy found morally wrong, for no other reason than greed. His relationship with his mother was presumably positive, as Cash exploited his care for her to manipulate his son.

In the circus, he performed with another imp child named Fizzarolli in a shared act. Despite enjoying working in the circus and his friendship with Fizzarolli, he hoped one day he would become famous enough and run his own circus; at the same time, however, he felt obligated to work to support his family, especially his mother.

During one performance, Blitzo's act caught the attention of a Goetiec Prince named Stolas, who was instantly smitten with the imp. Stolas' father, Paimon, then negotiated a deal with Cash to arrange a playdate for Blitzo and Stolas, but before trading his son to Paimon, Cash instructed Blitzo to rob from the Goetia household, reminding Blitzo of his loyalty to his family. While initially bored with Stolas in the mansion, Blitzo suggested they play a game of "pirates", which involved gathering all the most valuable items in the house. Blitzo then amassed a bag of treasure and tossed it to his father as he was hiding outside, before returning to Stolas. Outside the mansion, Blitzo inquired about Stolas' grimoire, to which Stolas explained it was for his duties and expressed his dream to join the Goetia family. Blitzo revealed to Stolas his dream was to run his own circus, and joked that one day he would hire Stolas to be part of it.

At some point after his encounter with Stolas, Blitzo and Fizzarolli's relationship somehow soured, and the two fell on bitter terms. In adulthood, Fizzarolli went on to become well-known in Hell, while Blitzo worked as a clown in Loo Loo Land who gave out balloons to children and performed some kind of show with jokes. It is known that Blitzo came to hate that job and it was an unpopular act, as well as hating Robo Fizz for being modeled after Fizzarolli, whom he at that point considered a "slutty toy clown".

Eventually, Blitzo quit the circus and went out on his own; in an attempt to separate himself from his past, he began insisting the "o" in his name was silent and started going by the shortened "Blitz".

Sometime in his life before the start of the series, he and Verosika Mayday entered a romantic relationship. The relationship was presumably tense and quickly ended after Blitzo stole her car and credit card, went to Wrath and used her money for horse-riding lessons.

4-5 years before the start of the series, Blitzo adopted a hellhound named Loona as his daughter.

At some point for reasons unexplained, Blitzo was imprisoned in the Greed Ring. His cellmate was Moxxie, who presumably aided in Blitzo's already-formed escape plan, which possibly involved shooting up an office.

At some point before the start of the series, Blitzo got the idea to start a freelance assassination business, which began as an operation in Hell.

Some time later, during a party Blitzo attempted to break into Stolas' mansion to steal the Goetic Prince's grimoire in order to obtain access to the living world. Blitzo was found and captured, but at the request of Stolas was granted an audience with the Prince in his room. Blitzo exploited his previous relationship with Stolas to seduce him and escaped with the enchanted grimoire the next morning.

Using the grimoire he had stolen from Stolas, Blitzo went on to formally establish a business of killing humans on Earth called Immediate Murder Professionals, and hired Moxxie and another imp as assassins along with his own daughter to work as the company's receptionist.
