Thanna

 was the Warrior-Princess of the Gothgolka Horde.

Her wedding with Kano Dollar was planned on Isen VI in presence of Thannagrrr, the Emperor of the Gothgolka Horde. For this occassion, Dollar's company, Dollar Intergalactic, was supposed to terraform the ice planet into a tropical paradise. An interference from Rann-Korr ruined the plans for both the terraforming and the wedding.

When Kano tried to escape Rann-Korr's carnage in his personal spaceship, leaving his wife-to-be behind, Thanna shot his spaceship down. (COMIC: Terrorformer)
