Vex: Dark Sirens
This is not a border game with sirens in the roster, it's a character Vex offers for players. Vex is described as a “dark siren” that has only recently unlocked her power, with her cynical and sarcastic behavior due to her rough upbringing.
“She is definitely the weirdest sirens we’ve ever had,” said Nick Thurston, the main game designer of Borderlands 4. “She was the first sirens to show the body creatures. She could summon the Reapers and Ghosts, and the first sirens to focus on dynamical damage. She could switch between all elements, but there was a heavy hook for those who liked the life steal or drown the souls of the enemy.”
Vex's third action skill, Phase Filipino, also allows her to summon a giant cat named “Trouble” based on Thurston's cat. Trouble is not only a cute nod to the developer's pet, but it can also help strengthen the idea of the witch theme behind Vex design. Gearbox also briefly explains how Vex's Dead Ringer skill works, as players will be able to summon a reaper that can be used to mock enemies or ghosts that can cause high damage but are vulnerable in combat. Vex can also apply elements to her subpoena and with the right adjustments, she can become a powerful crowd control character.
