Walter is the main antagonist of the episode "The Art of The Steal" from the animated series Doki. Walter is described as a grumpy and ill-tempered character who always responds aggressively and rudely to the others. He is also mean to everyone and rejects anyone who tries to befriend him. Walter, along with Anabella, is one of Giselle's art students who were going to reproduce a painting by Vincent Van Gogh (The Starry Night). Walter decides to steal the artwork to sell it later, so he creates a distraction with Anabella's camera and takes the painting without anyone noticing. With the painting in hand, Walter tries to escape from the art museum, but Doki and his friends manage to capture him. In the end, Walter is arrested for stealing a work of art and for framing a victim.
