The Ganuwa are an original race created for this story. They are zealots and have built their entire society around an intense hatred of the Brillar (the race they share a planet with). Ox like in appearance. Bull headed. The Ganuwan Commander is the only Ganuwa we hear speak and he/she only has one (all be it long) line. So though this is a small part it's very important and needs to have a lot behind it. The only desire of the Ganuwa is the complete extermination of the Brillar and "They'll build, buy, or steal whatever they need to do it." as Isamot Kol says.

The Commander should sound very smug and superior yet intimidating and overly confident. He/she has a ace up the sleeve when delivering this line that the Green Lanterns don't know about.
