text: A fan-created term<ref>URL="http://soul-hunter.com/sailormoon/entries/M.php"</ref> that refers to any expendable minion who appear in one (or, in some rare cases, two) episodes, serving under one of the more powerful villains to complete some nefarious objective. 
  
  Almost always, they are "healed" or die through one of [[Sailor Moon]]'s signature attacks (([[Moon Tiara Magic]], [[Moon Scepter Elimination]], [[Moon Spiral Heart Attack]], Rainbow Moon Heart Ache,[[Moon Gorgeous Meditation]]) with the exception being [[Leo the Lion|Leo the lion]] or by one of the Sailor Scouts (eg [[Sailor Mars]] fatally scorches the [[youma]] [[Kigaan]] as well as two of the [[Doom and Gloom Girls]].
  
  They appear in the anime, manga and live-action series of Sailor Moon "as well as various Sailor Moon video games<ref>URL="http://www.wikimoon.org/index.php?title=Monster-of-the-day"</ref>". The following monsters-of-the-day exist in the Sailor Moon series:
  * [[Youma]]
  * [[Cardian]] - kept inside cards working for [[Alan and Ann]] to drain energy for the [[Doom Tree]].
  * [[Droid]] - sent by the [[Negamoon Sisters]] ([[Catzi]], [[Bertie]], [[Avery]], and [[Prizma]], who were working for [[Rubeus]]), to take over crystal points, and later [[Emerald]], to fill Tokyo's vulnerable spots with dark energy. One droid, [[Grim Man]], worked for [[Prince Diamond]].
  * [[Daimon]] - who extracted pure hearts from humans under the orders of  [[Kaorinite]], [[Eugeal]], and [[Mimet]] in [[Sailor Moon S]]
  * Lemures or [[Remless]] -  who worked for the [[Amazon Trio]] and [[Amazon Quartet]] in order to defeat the Sailor Scouts whenever they tried to foil their plans as seen in [[Sailor Moon Super S]]
  * Phage - seen in Sailor Stars
  
  Each season always seemed to have one who has a more major role than other monsters. In ''Sailor Moon'', Zoycite's monster [[Housenka]] kills Neflite. In ''Sailor Moon R'', Alan and Ann's Cardian [[Racy]] breaks Sailor Moon's locket to detransform her, and she then receives more power from Queen Serenity. In ''Sailor Moon S'', Kaorinite's Daimon, [[Senishenta]], lasts for two episodes and her power is even absorbed by Kaorinite, and reflected back at her by Sailor Uranus to kill her. In ''Sailor Moon Super S'', [[Para Para]]'s Remless, [[Mr. Magic Pierrot]], directly kills [[Hawk's Eye]]&nbsp;and indirectly kills [[Tiger's Eye]] and [[Fisheye]] by destroying Serena's dream mirror, forcing them to give up their power to rebuild it.
