Monkey is a bouncing, loving, silly, playful, and energetic anthropomorphic monkey that loves to cause trouble. However, he is also sensitive and can easily hurt. He suffers from constant loneliness both when he was a subject of Umbrella and bullied because of how he was born, let alone the fact that his father wasn't there for him and his mother passed away after giving birth to her last child years ago. That changed when he was joined with Chi (Kai) and request joining with the Knights of the Dragons. While he still suffers from anxiety of being left alone and loneliness, even as an official member, his friends are always there to cheer him up.
