Los Dedos

"Los Dedos" (Spanish for "The Fingers") and her real name is Mary and is a local chess master from Mighty Mountain School.

Personality
At first she has somewhat of a crazy personality as she was seen calling Brain an amateur after beating him in a game of chess on numerous occasions. She also taps her fingernails, which drives her opponents crazy and is possibly the reason why she is a chess master. After Brain defeated her in another game of chess she gains respect for Brain.

Physical appearance
Los Dedos is a cat with a brown complexion. She wears a pink shirt with pink stripes and a white collar, blue jeans, and purple sneakers. She has brown hair wrapped in a ponytail.
