Domina

Domina was one of the independent Plants from the Earth fleet sent to deal with Knives. Domina has darkish hair and light-colored eyes. She wears a light-colored space outfit. In stark contrast to Chronica, Domina is shown to be more relaxed and emotional than her partner. Domina was taken over by Knives so he could know what moves they were going to make. As a result, she became absorbed by him. (Source: TRIGUN Wiki)
