Cinderella has lots of combat power and has the ability to manipulate glass. He also has a habit of cleaning, which he does to Grimm's entire mansion and the old school building, even seeming eager to clean up a litter covered beach.

Personality
Cinderella acts very cold to others, other than Grimm as an exception.

He serves Grimm like a butler and refers him as "domine" when taking orders from him.

Cinderella also has a courteous attitude towards Grimm, even though Grimm gets angry at Cinderella often. he is a masochist, seemingly to a degree as he claims to actually be in pain over certain injuries, such as when Red Riding Hood claws his back, and enjoys humiliating treatment, like being tied up.
