Scythebots are robots used by the villain Deathmonger. They are equipped with five scythes -- four for arms and legs, and one extending from their faces.
In Diseased Wench, Thugboy destroys three Scythebots with his fifty-caliber sniper rifle before Deathmonger destroys it, along with most of the building he was sniping from. However, as this occurs off-panel, no Scythebots are actually seen until A Very Long and Very Uncomfortable Eternity. In that story, Empowered and Sistah Spooky destroy a number of Scythebots while raiding Deathmonger's secret lair.
