Bell was a male Human Starfleet officer who lived during the mid-23rd century. He served in the command division aboard the USS Enterprise under Captain James T. Kirk, during a historic five-year mission that starship undertook.
In 2269, while the crews of the Enterprise and IKS Klothos were working together to free themselves of the Delta Triangle, Bell and Gabler served as relief guards in the dilithium vault. They reported discovering an unauthorized Klingon exchange officer in a secured area. (TAS: "The Time Trap")
