Zachary is a Standard Duelist in Yu-Gi-Oh! Duel Links. He only appears in Duel World (GX). Additionally, he cannot be unlocked, only appearing as an opponent. He can also be dueled in Duel Island: -Gladiator-.
Like many of the other male Obelisk Blue students portrayed in Yu-Gi-Oh! GX, Zachary is always portrayed as an elite snob to his opponent. He will automatically go into denial whenever he is defeated in a duel.
