The Borderlands franchise is known for three things: crass humor, an inordinate amount of guns, and memorable playable characters. It's these characters, Borderlands' Vault Hunters, who sit at the core of every franchise entry and provide the unique gameplay opportunities the series is known for. From the iconic Siren class to the fan-favorite Gunzerker, Borderlands wouldn't be the same without the creativity and charm of its many Vault Hunters. With the franchise moving on to its next entry, many fans are now wondering how developer Gearbox will continue to push the envelope with its playable characters.
