Blitzo/History

Early Life
Blitzo was born to Cash Buckzo and an unnamed female Imp, alongside his identical twin sister named Barbie Wire. Growing up, he worked in the family's circus ran by his father and ringleader. Blitzo's father (at least on one occasion) has 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, Blitzo yearned for more beyond his circus life, and hoped one day he would become famous enough and run his own business; 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 Goetia demon 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 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 a business, and joked that one day he would hire Stolas to be part of it.

Adulthood
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 was an unpopular act, as well as 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 (possibly already famous) Verosika Mayday entered a romantic relationship. The relationship was presumably tense and quickly ended after Blitzo stole her credit card to pay for horse-riding lessons.

4-5 years before the beginning of Helluva Boss, 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.

I.M.P
Eventually, Blitzo got the idea to start a freelance assassination business and attempted to steal Stolas' grimoire in order to obtain access to the living world. During a party at Stolas' mansion, Blitzo was granted an audience with Prince Stolas. He exploited his previous relationship with the Prince to seduce Stolas and escaped with the enchanted grimoire the next morning. Stolas knew the imp had stolen his property but sensing the pleasure he had from the night he had with Blitzo, Stolas cut a deal with him to be given access to the enchanted grimoire; in return, Blitzo would have monthly sex with the owl demon. Using the Grimoire, Blitzo went on to formally establish the Immediate Murder Professionals and hired two fellow imps as assassins and Loona to work as the company's receptionist.
