A brief presentation of Moze
Former Vladof soldier turned Vault Hunter, Moserah Hayussinian Yan-Lun al-Amir Andreyevna (better known as “Moze”) is a highly skilled gunner who can summon a large mech called Iron Bear in Borderlands 3.
Moze was a Vladof soldier in the Ursa Corps, a mechanized infantry division that used 15-ton “Iron Bear” mechs. She rose to the rank of Gunner First Class and had to fulfill a mission quota to keep her mech. Her superior, Kaziak, manipulated her to stay longer, but she eventually quit after a final mission where her squad perished, and Vladof assumed her death.
In Borderlands 3, Moze is depicted as a muscular woman with short, dark hair and brown eyes. She has several tattoos on her arms, shoulders, and back, including a Vladof logo on her left bicep. Moze wears a red and black Vladof military uniform with heavy armor plates and a helmet that conceals her face.
She is a versatile character who can summon Iron Bear, a customizable weapon that enables her to adapt to different combat situations, whether solo or in co-op play. Moze’s style is ideal for players who enjoy both heavy firepower and strategic maneuvering.
