# Koby #EB04-044 — Adventure on Kami's Island

## Summary

Koby went from Alvida's cabin boy to a Marine who stands in front of admirals, and his rise through Marineford and the Navy's ranks is why fans root for him. This Super Rare from Adventure on Kami's Island (EB04), released in April 2026, catches him mid-kick with pink hair and green goggles against a pale, streaked blue backdrop. Black Navy decks run him at six cost for the draw engine and the discard-to-survive protection. A $0.47 modelled guide with no copies traded in 30 days says bulk, and the economics stop there: no PSA population is on file.
