Doll Monster

"Doll Monster" (ドール・モンスター, Dōru Monsutā) is an archetype used by in the Yu-Gi-Oh! ZEXAL manga and in Rocket Knight 777's fanfiction universe. It is a sub-archetype of the "" archetype. In the manga, the archetype is composed of Normal Monsters with toy themes, and they are supported by the Field Spell "", which allows the user to Special Summon improved versions of them with higher Levels each turn.

In RK777's universe, they are mostly low-Level Effect Monsters. Some of them, like the monsters found in the manga, are treated as Normal Monsters while on the field or in the Graveyard. Others have effect that mimic what they are based on, like Doll Monster Choo-Choo Train's effect to Special Summon Doll Monsters from the Deck when it is Normal Summoned. All Doll Monsters, however, have the following effect "When this card and at least 1 other Doll Monster are destroyed (by battle or card effect) this turn and sent to your Graveyard, during the Standby Phase of the next turn; banish this card, then Special Summon all other Doll Monsters that were destroyed this turn. The Level(s) of all monsters Special Summoned this way becomes the Level they had when they were face-up on the field +2."

Etymology
All "Doll Monsters" are named after popular infant toys (a doll, a toy dragon, a teddy bear, and a toy robot). In the Japanese version, their names end with a Japanese suffix ("-chan", "-kun", "-chi" and "-chin", respectively), making their names become loving cute names, which would normally be given to the toys by the kid who owns them.
