Statue Armour Ghost

Knight Greenies are Strong Greenies in Luigi's Mansion: Dark Moon that are in a suit of armor, therefore gaining abilities that other Greenies don't have. To attack Luigi, Knight Greenies charge at him fairly fast, then attack with their weapon, dealing 20 damage if successful. However, if they don't hit Luigi, the Greenie will have to pull the weapon out of the ground, taking time to do so, this is when Luigi can reveal the Greenie beneath the suit, by using his Poltergust 5000's Power Surge on the carpet it is standing on, making the knight fall which breaks its suit of armor, revealing a Greenie. The fight after that is just sucking the Greenie up.

Knight Greenies are only fought and seen in E-1: Front-Door Key. Luigi encounters them in the Ceremonial Chamber, having to beat two of them to get through. In E-Boss: Stop the Knightmare 6 suits of armor are possessed by the Tough Possessor.
