Vaatrik Drasa was a male Bajoran who lived in the 24th century. In the 2360s, Vaatrik owned a chemist on Terok Nor's Promenade and collaborated with the Cardassians. Vaatrik was married to Vaatrik Pallra.
In 2365, Kira Nerys killed Vaatrik after attempting to locate a list of Bajoran collaborators that Vaatrik had. Dukat assigned Odo to investigate, although Kira's involvement was not revealed until Vaatrik Pallra attempted to obtain the list of collaborators using Quark in 2370.
