Wasa Graim was a male Bajoran who served in the Bajoran Militia in the 2370s.

In 2376 Wasa was in his fifties, he had two teenage daughters and had reached the rank of Sergeant. By then he had been posted on Deep Space 9 for some time and had a reputation as one of the best shots on the station. He had trained many members of the rest of the station's security personnel.

In April of that year, Wasa joined a security team who accompanied Kira Nerys and Elias Vaughn to the station's fusion core in pursuit of the Jem'Hadar, Kitana'klan. Once the team found the Jem'Hadar, as the best shot, Wasa was to lead the assault. But before the Bajoran could even take his first shot the Jem'Hadar sensed him and moved out of shot, moments later Wasa was dead from a shot to the chest by Kitana'klan. (DS9 novel: Avatar, Book Two)
