Paul Wan, also rendered as Paul Wang, is a supporting character in the anime Getbackers. He is the owner of the Honky Tonk, a small cafe in the back streets of Shinjuku where the retrieval specialists Ban Mido and Ginji Amano gather between jobs, and his establishment effectively serves as the pair's base of operations. He is in his mid-thirties, stands 180 centimeters tall, and carries himself with a calm, steady presence. Although he is frequently shown reminding Ban and Ginji that they must first pay their tab, he regularly lets the two eat and drink on credit, sometimes bearing their hunger himself so that they can be fed, and he tolerates the occasional damage the pair, especially Ban, cause inside his shop.

In terms of personality, Paul is wise, philosophical, and composed, and he acts as a father figure to the younger characters who gather around him. He is known as a master coffee maker and an attentive listener, and he habitually offers information and coffee to anyone who talks to him. He has a natural gift for cheering up people who are feeling down, and his advice often steadies Ban and Ginji during difficult moments. His willingness to help goes beyond conversation, as he occasionally assists the GetBackers directly by gathering information and by accompanying them as a chaperone on certain missions.

Paul's past is not explored in depth for most of the anime. In the anime, his background is revealed in the forty-second episode, where it is shown that he was once part of a trio of thieves before settling down as a cafe owner. The original manga presents a different and considerably more significant history, revealing that Paul and Ban's father were the first generation of the GetBackers and that, in their time, they climbed to the top of the Infinity Fortress and even entered Babylon City. This earlier history adds depth to his role as a mentor, though the anime leaves most of that legacy in the background.

Paul does not rely on supernatural abilities, and his strengths lie in his experience, his network of contacts, and his steady temperament. One notable limitation is his fear of heights, which occasionally surfaces during missions. His motivations are grounded in support rather than ambition: he watches over Ban and Ginji, provides them with a safe place to operate, and helps them whenever he can, all while maintaining the gruff pretense of a shopkeeper more concerned with unpaid bills. He does not undergo major personal change over the course of the story, but the gradual revelation of his history gives additional weight to his quietly protective presence among the cast.
