A Chester is an enemy that appears in Super Mario RPG: Legend of the Seven Stars. It is a small monster inside of a treasure chest that can only be fought in Bowser's Keep where it is found behind one of the six doors.
The Chester is weak against Jump attacks so Mario should use his strongest jump move, Ultra Jump, against it. Geno should give Mario an extra boost with Geno Boost while Princess Toadstool works on healing.
- There is another Chester found in Monstro Town but it's friendly. It will keep track on how many invisible chests Mario has found throughout his adventure.
