Gigazelle is a monster-like Mirror Monster from Kamen Rider Ryuki, not a human character. It appears in the Mirror World and serves as one of the many threats that Riders must fight while competing in the Rider War. Gigazelle is part of the creature forces tied to the Mirror World’s dangerous ecosystem, often acting as an enemy encounter rather than a story-driving individual. Its role is to challenge the protagonists and emphasize the constant danger of the mirror dimension.
