Bill

In The Supercat Video Universe, Bill was initially hired as a hitman by Jamie. However, when Jamie's plan failed and resulted in the creation of two additional versions of Callum, Bill's role became more complex.

Bill's first target was Meme Man, who was searching for a gun. To approach Meme Man, Bill disguised himself as a Gun Dealer and offered him a free firearm. In exchange, Bill required Meme Man to work for him.

Bill devised a scheme where Jamie posed as a target, intending for Meme Man to eliminate him. However, Bill deceived Meme Man by making him believe he would kill the disguised Jamie. Consequently, Meme Man surrendered his gun to Bill, who used it to fatally shoot him.

During the events in the Video Universe, Bill also murdered Harry. Ultimately, he engaged in a death battle with Callum in the finale, but was later resurrected alongside Jamie and Harry through a "Time Reset."

To aid in the search for one of Callum's personas, who resembled Sonic The Hedgehog, Bill adopted the persona of "Knuckles." Both Bill and Knuckles experienced side effects from magic, resulting in them having blond hair.

Following the "Time Reset," Jamie asked Bill if he would consider quitting his profession as a hitman. Surprisingly, Bill expressed his lifelong aspiration to become a hairdresser.

In The Supercat Video Universe: Volume 2, Bill contemplated leaving his hitman job to pursue a career as a hairdresser. After careful consideration, he made the decision to quit. Symbolizing his departure, he threw his beanie into a river and discreetly disposed of his guns off-screen.

Bill's elation over leaving his hitman life was short-lived when a sudden flash occurred, and he found himself holding a gray hoodie resembling JJ's from Captain Callum Adventures. Confused about its origin, Bill wandered until he discovered the source: a magical stone resembling the one possessed by Mullac, which then teleported into Captain Callum's dimension.

Soon after, Jamie called Bill, prompting him to rush off. In his haste, Bill discarded the gray hoodie.

On his way to meet Jamie, Bill accidentally collided with Mullac, causing him to drop the stone temporarily. Bill swiftly retrieved it. Mullac recognized an opportunity to convince Bill to surrender the stone, although Bill believed it to be an ordinary rock.

Refusing to relinquish the stone, Bill attempted to flee, but Mullac halted him and initiated a fight. Despite Mullac finding a gun and holding Bill at gunpoint, Callum intervened, causing himself to also be held at gunpoint with Bill.

Bill and Callum devised a plan to distract Mullac by offering him the stone. As Mullac reached for it, Bill and Callum seized the chance to escape and reclaim the stone. They left Mullac on the beach and proceeded to meet Jamie, only to discover he was missing from their rendezvous point, The Underpass.

Bill and Callum separated to search for Jamie, but their efforts were fruitless. During a conversation about the chaos in his life, Bill was unexpectedly shot in the chest by Mullac from behind one of the pillars. Before passing away, Bill defiantly told Mullac to "Go to Hell, you tall-ass twelve-year-old."

In Volume 3, there's a flashback sequence where Mullac reflects on Bill's death. This memory unfolds as Mullac accidentally comes across the location where he killed Bill. It's evident that Mullac harbors some regrets about deciding to end Bill's life, and this recollection causes him considerable distress. This emotional turmoil is highlighted by his quick departure from the scene.
