"Heart Monster" is an archetype used by Mr. Heartland in the Yu-Gi-Oh! ZEXAL manga. With the Field Spell Card "Land Power", similar to Toon Monsters, "Heart Monsters" gain the ability of attacking the opponent directly while preventing the opponent from attacking them. Additionally, "Heart Monsters" have unique effects which can only be activated when "Land Power" is destroyed. "Heart Monsters" all have cute appearances and hearts somewhere in their bodies. Their names are portmanteaus with the word "heart".
