Milo has found his way into the wizarding world after he had just taken out a Wizard in New York City's MACUSA Headquarters, taking his wand in the process. After taking some time to study how everything worked, he managed to find his way into the UK through a special portal connecting the two countries. He then heard about a notorious death eater by the name of Barty Crouch Junior, finding that they had several similarities of being betrayed by their own families, wanting to seek him out in hopes of forming a partnership for revenge. Now Milo and Barty are partnered up and are ready to cause chaos in both the wizarding and the Marvel world.

Milo, born Lucien Crown, was a wealthy scion and life-long friend of Michael Morbius; both suffering from the same rare blood disease. Milo used his considerable wealth to support Horizon Labs' experiments, in hopes of finding a cure for his illness. He became a vampire by stealing and taking a dose of Michael's vampire serum, and now he's running loose on the streets. Character is based off the 2022 movie, Morbius, and is played by actor, Matt Smith.

Bartemius "Barty" Crouch Junior was a wizard and the son of Bartemius Crouch Senior. He became an ardent follower of Lord Voldemort in order to become a Death Eater and Dark wizard in his teenage years. He was the first escapee of Azkaban prison in its almost 300 year history, though only his father, late mother and the family house-elf knew until 1995, when it was revealed to Albus Dumbledore, Harry Potter, Minerva McGonagall and Severus Snape whilst Crouch was under the influence of Veritaserum. In 1981, shortly after Voldemort's first defeat, Crouch allegedly participated in the capture and torture of Frank and Alice Longbottom along with the Lestranges, using the Cruciatus Curse to drive the two Aurors to insanity. Character is based off the 2005 movie, Harry Potter and the Goblet of Fire, and was played by actor, David Tennant.
