Morphoser

Morphoser ( Morufōzā) is an Archetype of Insect-Type monsters of all Attributes created by Taylor Gorrell. The Main Deck monsters are Level 4 insect larvae with traits of their corresponding Fusion Monsters, a sub-Archetype of monsters known as "Meta-Morphoser" ( Meta Morufōzā), which are Level 7 anthropomorphic insects (even those that don't have larval stages) with various powers. All Level 4s have "va" as part of their name, deriving from "larva".

Morphosers focus greatly on utilizing Transformation Summon, using single monsters to bring out Meta-Morphoser Fusion Monsters, as if hyper-evolving from larva to adult. Morphosers use "Pupa" Quick-Play Spell Cards to initiate their Transformation Summons. Though certain Morphosers are not required to Summon certain Meta-Morphosers despite each set matching each other, Meta-Morphosers all have an extra effect that only comes into play if the matching Morphoser was used to Summon them, similar to most Xyz Monsters.
