Borderlands 4: The Status of Every Siren Going Into the New Game

The Sirens of the Borderlands universe are a constant source of mystery and intrigue. These powerful, magically-tattooed women are central to the franchise’s lore, with their abilities and lineage often driving the main narrative. With Borderlands 4 set to launch on September 12, 2025, fans are buzzing with speculation about the fate of the Sirens and what new powers will be introduced. The core lore of the series states that there can only be six Sirens at any given time, each with a unique ability. The events of Borderlands 3 left the status of some Sirens up in the air, creating a fascinating puzzle for the new game to solve. This article will break down the current status of every known Siren as we head into the new era of Borderlands 4 and what their presence means for the game’s story on the new planet, Kairos.

The power of the Sirens is passed down upon their death, making their mortality a crucial part of the lore. The dramatic conclusion of Borderlands 3 saw the death of a major character, leaving a power vacuum and a big question mark over who would inherit her abilities. With the new Vault Hunter, Vex, confirmed to be a Siren with a previously unseen ability, the count of active Sirens becomes a key plot point for the new game. The mystery of the “seventh Siren” and the unknown whereabouts of others also add a layer of suspense to the narrative, making the hunt for these powerful characters a central theme.

The Confirmed Living Sirens

The conclusion of Borderlands 3 and the pre-release information for Borderlands 4 have given us a clear picture of who is still active in the Siren roster. Their powers and continued existence will be a major part of the game’s story, with some even appearing as returning characters.

• Amara (Phasegrasp, Phaseslam, Phaseflare): Amara, the playable Siren from Borderlands 3, is confirmed to be alive and a returning character in Borderlands 4. She is a battle-hardened hero with a no-nonsense attitude. Her abilities, which include summoning ethereal fists and a powerful flare, are still active and will likely be a major asset to the new Vault Hunters. Her presence on Kairos, the new planet, suggests she has been fighting the good fight and will be an important ally.
• Ava (Phaselock): Ava, who inherited Maya’s Phaselock ability at the end of Borderlands 3, is confirmed to be alive and a part of the main story in Borderlands 4. She has been training to master her new powers and has taken on a leadership role in the Crimson Raiders. Her journey to become a true hero is a major part of her character arc, and her Phaselock ability will undoubtedly be put to the test against the new threats on Kairos.
• Patricia Tannis (Phaseshift): Tannis, who was revealed to be a Siren in Borderlands 3 and the inheritor of Angel’s Phaseshift ability, is confirmed to be alive. Her power to “shift” objects to different dimensions makes her a valuable asset, and she will likely play a role in unraveling the mysteries of the new planet and its inhabitants. Her dry wit and eccentric personality are sure to be a welcome addition to the cast.
• Vex (New Siren): The new playable Siren in Borderlands 4 is named Vex. Her ability has not been explicitly named, but it is a new power that has not been seen before in the series. This means that she is the inheritor of one of the two missing Siren powers. This new ability, whatever it may be, will be a central part of her unique playstyle and will be crucial to the game’s narrative.

The Status of Missing or Unaccounted-For Sirens

The Siren count is a constant source of fan speculation. With the confirmed living Sirens, we are left with two major question marks: the fate of Lilith and the identity of the Phaseleech Siren, which was previously held by Tyreen Calypso.

• Lilith (Phasewalk): At the end of Borderlands 3, Lilith used her powers to teleport the moon Elpis, saving Pandora from a devastating collision. She was seemingly consumed by the blast, and her current status is unknown. She is presumed dead by many, which would mean her Phasewalk ability has been passed on to a new host. However, the game’s lore is often complex, and there is a possibility that she is still alive in some form. Her return would be a monumental event and a major plot twist in the new game. Her status is one of the biggest mysteries going into Borderlands 4.
• The Phaseleech Siren: The Phaseleech ability, which allows a Siren to absorb the life force and powers of others, was previously held by Tyreen Calypso. Upon her death, her power was seemingly passed on to an unknown successor. The new playable Siren, Vex, has a different ability, which means the Phaseleech power is still out there, held by an unknown character. This is a terrifying thought, as the ability is incredibly dangerous and could be in the hands of a new villain. The hunt for this new Siren will likely be a central theme in the game, and the mystery of their identity is a major part of the pre-release hype.

The fate of Commandant Steele, the Siren from the first game, is a more clear-cut case. She was confirmed to be a Siren in the comics and was killed by the Vault Hunters in the first game. Her Phasestrike ability was likely passed on to a new host, but it’s not a major plot point in the new game.

Conclusion: The Future of Siren Lore

The roster of active Sirens going into Borderlands 4 is a mix of returning fan favorites and intriguing new mysteries. The fact that the new playable Siren has a previously unseen power is a huge deal for the lore, as it means we will finally learn about one of the missing Siren abilities. The status of Lilith and the identity of the new Phaseleech Siren are the two biggest questions that the game will likely answer. The developers have a great opportunity to expand on the lore of the Sirens, and the new narrative on Kairos seems to be the perfect setting for a deep dive into these powerful beings. The lore is more complex than ever, and the fate of these characters is a major reason why fans are so excited to get their hands on the new game. The hunt for the perfect loot is a big part of the game, but the hunt for the perfect lore is what keeps the story engaging, and the mystery of the Sirens is a big part of that. The future of the Siren lore is an exciting and unpredictable one, and it’s a big reason why Borderlands 4 is shaping up to be a true evolution of the franchise.
