The Real-Life Star: Peggy, Britain’s ‘Ugliest Dog’

One of the most compelling and current stories surrounding Dogpool is that of the real-life dog who plays the character in the Deadpool & Wolverine film. Her journey from a rescue dog to a Marvel star is a true Hollywood underdog tale.

From Rescue to Red Carpet

The dog who portrays the cinematic Dogpool is a female Chinese Crested/Pug mix named Peggy. Peggy’s unique look, which includes a slightly patchy coat and an endearing underbite, led her to an unexpected moment of fame in 2023 when she won the title of Britain's Ugliest Dog. This win, widely publicized in the media, is what caught the attention of actor and producer Ryan Reynolds.

Reynolds, known for his love of quirky and unique characters, personally reached out after seeing Peggy’s story. He saw her "unique beauty" as the perfect fit for the chaotic, unconventional role of Dogpool. Peggy’s casting is a major win for rescue animals and highlights a positive, current trend in Hollywood of casting dogs based on character rather than traditional aesthetics.

The Movie Variant: Mary Puppins

In the 2024 film, Dogpool is introduced as a Variant who is banished to The Void by the Time Variance Authority (TVA), the same fate that befalls other multiversal castaways. Her official movie Variant name is Mary Puppins, a classic Deadpool-style joke that pairs a sweet, innocent name with a chaotic character. She is first encountered by Wade Wilson (Deadpool) and Wolverine alongside her owner, another Variant known as Nicepool. Her role is pivotal, serving as a loyal companion and a source of both comic relief and emotional grounding for the main heroes as they navigate the desolate landscape of the Void.

The Comic Book Origin: Wade Wilson on Earth-103173

While the movie version is a new Variant, the original comic book Dogpool has a backstory that is classic Deadpool: a tragedy-turned-superpower born from failed science experiments. This is the origin of the male Dogpool named Wade Wilson from Earth-103173.

The Mascara-X Experiment

In his original reality, the dog named Wilson was a test subject for a company attempting to create a revolutionary, replenishing cosmetic product called Mascara-X. This experiment, a twisted parallel to the Weapon X program that gave the human Deadpool his powers, failed dramatically. Instead of a perfect cosmetic, the result was a grotesque, disfigured dog with extraordinary abilities: an Accelerated Regenerative Healing Factor and near-invulnerability.

This healing factor is Dogpool’s signature power, allowing him to survive injuries that would instantly kill any normal dog. The comic version of Wade Wilson was later recruited by the Deadpool Corps, a team of multiversal Deadpool Variants, including Headpool (a zombie head), Lady Deadpool, Kidpool, and Major Deadpool.

Dogpool’s Future in Marvel: Comics and the MCU

The massive popularity of the character in Deadpool & Wolverine has secured Dogpool’s future in the Marvel universe, both on screen and in print. This is one of the most important, up-to-date facts about the character.

• New Comic Series: At the San Diego Comic-Con (SDCC) in 2024, Marvel Comics announced they would be putting a new spotlight on the character. This move confirms that Dogpool is no longer a minor footnote but a character Marvel is investing in heavily, capitalizing on the cinematic success.
• Potential MCU Return: Given her survival and strong connection with Wade Wilson and Wolverine, the movie variant, Mary Puppins, is highly likely to return in future MCU projects. Ryan Reynolds's enthusiasm for the dog and the fan reaction makes her a natural choice to become a recurring sidekick.
• Topical Authority Entities: The character is a vital link between the cinematic and comic multi-verses, solidifying her as a high-value entity in current Marvel lore, connecting concepts like the TVA, the Void, Variants, and the Deadpool Corps.

Dogpool, whether as the comic book Wade Wilson or the cinematic Mary Puppins (Peggy), has cemented her place as a fan favorite. Her story is a delightful blend of dark humor, superhero action, and an inspiring real-life tale, making her one of the most unique and enduring characters to emerge from the recent wave of Marvel multi-versal content.
