Fans Speculate the New ‘Agatha All Along’ Promo Unveils Rio Vidal’s True Identity

Agatha All Along, the latest hit in the MCU, has been making waves with both fans and critics alike, as you may already know. The WandaVision spin-off underwent several title changes before settling on its current name, and we were surprised that it stuck when the show premiered.

The first two episodes dropped on Disney+ on September 18, 2024, with the remaining seven episodes releasing weekly until the finale on November 6.

We’ve been closely following the series, focusing on its characters, particularly Aubrey Plaza’s mysterious Rio Vidal. Fans are convinced that “Rio Vidal” is a cover for something far more sinister, sparking numerous theories about her true identity.

Speculation has ranged from Mephisto to Blackheart, but a recent promo suggests Rio Vidal might be one of Marvel’s most powerful supernatural figures. Want to know who? Keep reading to find out!

Aubrey Plaza’s character in Agatha All Along remains one of the show’s biggest mysteries, alongside Joe Locke’s character, the Teen. While we have a good idea of the Teen’s identity—thanks to various hints and a potential trailer slip-up—Rio Vidal’s true nature is still shrouded in secrecy.

Although she could simply be a new character, many fans believe there’s more to her than meets the eye, suspecting that she’s not who the writers want us to think. Given Plaza’s A-list status, it would make sense for her to play a more significant role in the series.

Fans believe that the Ouija board scene, where the letters spell out D-E-A-T-H, suggests that Rio Vidal is actually Lady Death, a pivotal figure in Marvel’s lore. Lady Death is famously pursued by Thanos while harboring feelings for Deadpool. Supporters of this theory point to several other clues throughout the series that seem to back it up:

As you can see, fans have gathered several clues to support the theory that Rio Vidal is Lady Death. While we can’t confirm this yet—and the Ouija board scene may ultimately have no connection to Vidal—it will be fascinating to see how the story unfolds. Stay tuned for more updates as we continue to follow this mystery!
