Canisian

Canisians were a warlike humanoid species from Alpha Canis One.

During the 21st century, the Canisian Empire came under the control of Tannis, who led them in an invasion of Earth. (WC: Death Comes to Time) During the invasion, Felix Mather was Secretary of State. (PROSE: Trading Futures)

At some point they quit their war-mongering ways to become a peaceful species, even turning to celebrating Earth history with a convention at Canis Major Overdensity Convention Center and Resort. (COMIC: A Doctor in the House?)
