Aubrey Plaza as Lady Death in Agatha All Along? Theories and Insights Explained

Although Aubrey Plaza has disclosed the full name of her character in Agatha All Along, there remains a possibility that she is concealing her true identity from the audience.

The Agatha All Along series, a spinoff of 2021’s WandaVision, has several critical questions to address in its remaining seven episodes.

While many theorize that the primary mystery revolves around Joe Locke’s character, Teen, another enigma has emerged. Plaza’s true role in the storyline of Agatha is now under scrutiny.

Her character, Rio Vidal, has been prominently featured across the new Marvel show’s promotional content. However, what if she is utilizing this as a facade, potentially portraying Lady Death? Is it possible that fans are overlooking a secret third identity that she may embody?

Here’s everything we currently know about Aubrey Plaza’s character in Agatha All Along.

Is Aubrey Plaza playing Lady Death in Agatha All Along?

As of now, Aubrey Plaza is not officially confirmed to be portraying Lady Death in Agatha All Along.

Nevertheless, some fans speculate that the latest promotional trailer might suggest that Plaza’s true role in the series is indeed connected to Lady Death.

In the trailer, Agatha and her coven can be seen engaging with a ouija board, with Agatha saying, “Someone is here with us.” Subsequently, the planchette they hold moves across the board, landing on the letters ‘D’ ‘E’ ‘A’ ‘T’ ‘H.’

With Episodes 1 and 2 currently available, we have gleaned a substantial amount of information about Agatha’s coven of witch “friends,” aside from Rio and Teen.

Teen appears to be under a spell that obscures his identity from both the audience and the characters within the show. However, Agatha is the only one privy to Rio’s true identity beneath her hardened facade.

From their limited exchanges, it’s evident that the two women share a tumultuous past that Agatha seems reluctant to confront. But what if this hesitation stems from the fact that Rio is, in fact, Death herself?

In Marvel’s comic lore, Death is depicted as being able to assume any gender, often portrayed either as a skeletal figure clad in a dark robe or as a woman in a hooded cloak, similar to what Rio donned during her confrontation with Agatha.

Throughout the comics, Death has interacted with various characters in the mortal realm, particularly Thanos, who pursued her after they forged a bond through their shared affinity for death, and Deadpool, who developed feelings for her during the 2002 storyline “Funeral for a Freak.

This theory posits that Plaza could be playing Lady Death, especially since fans have frequently heard that the witches’ journey is perilous, often leading to irrevocable outcomes—precisely the path the group seems to be navigating.

If this speculation holds true, Rio’s involvement with Agatha and her coven might herald doom for all.

Alternative identities for Plaza’s character

If it turns out that Plaza is not portraying Lady Death, there are other possibilities for her character’s identity, including Morgan le Fay or Mephisto’s daughter, Blackheart.

In the comics, Morgan le Fay is depicted as a human/fairy hybrid and is King Arthur’s half-sister. Her fairy lineage granted her immortality, which she used to master magic over centuries.

She attempted to conquer the world alongside her lover, Doctor Doom, which led her to face off against the Avengers.

Morgan was also known to be the custodian of the Darkhold—the ominous book of magic that bestowed powers upon Agatha, which was ultimately appropriated by Wanda Maximoff at the conclusion of WandaVision.

Since Rio has known Agatha for centuries and is considered a “green witch” —or someone deeply connected to the elements akin to a fairy—there’s a compelling argument for her identity as Morgan.

The alternative identity could have Rio revealing herself as Blackheart, the daughter of Mephisto. Mephisto embodies the MCU’s interpretation of the devil, frequently mentioned during WandaVision due to his ties to Scarlet Witch’s comic-related story arcs.

Interestingly, Rio confesses to Agatha that her heart “is black… and beats for you,” potentially alluding to a clever admission of her identity as Blackheart.

In this scenario, Plaza would be presenting a gender-swapped version of the character, as traditionally, Mephisto’s son, Blackheart, was born from the immense evil energy in Christ’s Crown, New York.

Despite their familial ties, Blackheart often clashed with his father, leading to his abandonment on Earth without any powers.

Given the strong fan interest in Mephisto’s inclusion in the WandaVision narrative, Agatha All Along might use Rio as the conduit to finally introduce the devil into the MCU.

Episodes 1 and 2 of Agatha All Along are now available for streaming on Disney Plus. In the meantime, check out our breakdown of Salem’s Seven and Nicholas Scratch for more insight.
