A Transformation Summon (変（へん）身（しん）召（しょう）喚（かん） Henshin Shōkan) is when a Fusion Monster is Special Summoned using the effect of a specific card, and without using any Fusion Materials (and the Special Summon is not treated as a Fusion Summon). This type of Summon is featured in the Yu-Gi-Oh! GX manga in "Masked HERO" archetype.
