Miss Monday

Miss Monday is a number agent of Baroque Works and partner to to Igaram (Mr. 8 at the time) during his infiltration within the Baroque Works.

Information
Not much is known about her other than that she has incredible strength, as indicated by her muscle mass and huge size. Another distinctive feature of hers is her soft, high pitched voice more commonly associated with small, frail girls (which helps when it comes to disguising, as seen when she posed as a nun without her true size and strength being noticed). Miss Monday, along with Mr. 8, Mr. 9, Miss Wednesday (Princess Vivi) and every resident on Whiskey Peak fight against Zoro after he finds them out to all be bounty hunters. While Monday manages to get some hits in, she is soon easily defeated by Zoro during his rampage.

Later after Vivi is exposed by Mr. 5 and Miss Valentine, Monday tries to hold them off saying that Vivi was her friend, and that she would be killed anyway for failing to defeat Zoro. She was quickly knocked out when Mr. 5 clotheslined her throat with an exploding arm before Miss Valentine crushed her with a 10,000 Kilo Press. She is presumed dead.

Abilities
Miss Monday uses her superhuman strength in battle, typically attacking with her fists or nearby objects.

Other Appearances
In Episode 292, which takes place in an alternate reality set in Feudal Japan, Miss Monday chases Zoro out of the women's room of the castle when he wanders into it after getting lost pursuing the mochi thieves.
