Event

CYBER UPDATE

Gym Bros is a Secret brainrot in Steal a Brainrot and one of the heavier duo designs in the Cyber lineup. It appears as a red weightlifter mascot perched on top of an orange blocky workout partner with long limbs, a giant barbell, and white sneakers. Gym Bros matters because it adds a stacked gym-themed duo that feels visually different from the rest of the current cyber mascots.
