Converts hair follicles along the scalp's mohawk line into feather-producing follicles, creating a crest of genuine feathers along the crown of the head. The feathers are structurally authentic — barbs, barbules, and rachis — and can be produced in any color combination using chromatophore co-modification. Peacock-iridescent crests are the current fashion peak in GLMZ. The feathers grow, molt, and regrow on a cycle similar to modified hair. They can be styled, trimmed, and arranged like hair but have the unmistakable texture and light-catching properties of real plumage. Lacuna Genomics offers full-head feather conversion for users who want to replace all their hair with plumage, but the mohawk crest remains the most popular configuration. The feathers are waterproof and self-maintaining through preening — a behavior that users develop naturally.
