Glum Reaper

Glum Reapers are scythe wielding Boo Guys found in Super Mario RPG: Legend of the Seven Stars. Glum Reapers resemble a cross between the Grim Reaper and a Boo Guy. Mario and his companions encounter Glum Reapers at the Factory. In battle, Glum Reapers were extremely versatile spellcasters with an arsenal of death related attacks, including the auto-death causing attack, Scythe. Fortunately, Glum Reapers have low defense and HP, so they can be taken out before they can cause major damage. Glum Reapers resemble an earlier enemy encountered in Mario's quest, the Greaper; however, Glum Reapers have lighter robes and their scythes are golden. It is unknown what connection Glum Reapers had with Smithy and may just be inhabitants of the Factory.

Trivia

 * Their name is a pun on the Grim Reaper, the personification of death. Their designs also stem from his common portrayal of wearing a robe and carrying a scythe.
