Tana sees the Rock Trolls' invasion on the news, and she follows Silas Grant to combat them, though not before changing back to her Rigellian form. Tana makes use of her stasis gun to distract Ulik from attacking Thor, and later to weld the hole that the Trolls emerged from shut.
She accompanies Thor to find a maddened Balder who keeps repeating the word 'Asgard'. Tana then follows Thor with the others back to an empty Asgard, finding a sentient alien race of lizards - the Sssth - there instead. Tana travels with the lizards, who claim they are slaves and that the Asgardians have been kidnapped by another alien race - the Vrellnexians - to stop Odin and the Asgardians being sold into slavery. She combats a crowd of alien slave traders and they overcome them, only to find the Sssth have betrayed them and they are surrounded.
She attacks the numerous Sssth, but she and her companions are ultimately defeated. She is locked up with Hildegarde in a dungeon separate from everyone else, and they manage to avoid the drugged broth that is sapping everyone's wills long enough for Thor to escape and free them. She sneaks throughout Golden Star until they encounter a group of hidden alien freedom fighters. They form a plan to overcome the Sssth and free the prisoners simultaneously, and Tana is sent to return to the dungeon and free the captives while Hildegarde and Thor defeat Sssthgar. They succeed, and reconvene, leaving the heroes with no further task, so they leave the planet to return to Asgard.
She accompanies Thor's group into the Dark Nebula in search of Sif and Karnilla. On the journey, she asks Hildegarde to tell the story behind Sif's disappearance. When they reach the Nebula, they find an asteroid and three hostile miners who mistake them for besieging Gramosians, an alien race whom Thor had encountered before, in the form of Mercurio, the 4D man. Mercurio appears with his forces and attacks the Asgardians. Soon after, however, the battle is quickly interrupted by a huge red jewel rising out of the asteroid that has trapped Sif and Karnilla within.
She listens to Xorr's warnings and can do naught to attack because of Sif and Karnilla's entombment within the God-Jewel. They are plunged into a cavern and form a temporary alliance with Mercurio to allow them all to escape. They battle the now hypnotised miners and reach the surface, but a spaceship piloted by the lead miners has taken hold of the God-Jewel and is flying away. They pursue the ship, and Thor destroys their weaponry with Mjolnir, allowing the Asgardians to eventually catch up. Tana is beaten back by Kagg's molecular disruptor, which Odin is able to destroy, but Thor refuses to destroy the God-Jewel and Xorr remains empowered.
She waits under Odin's command, rather than attacking Xorr. As the others bring about Xorr's defeat, she worries about Rigel and an oncoming threat.
She returns to Asgard with the band, but they find imposters in their place. Tana battles the duplicates. Igron is revealed as the true villain, and is defeated by Balder and Thor. The imposters soon fade. Odin soon summons Tana, among others, to his presence, and informs them that a great danger is approaching the Rigellians.
She departs for Rigel-3 upon the Asgardian starjammer, and finds the planet abandoned, save for a race of mutant Rigellians, whom they are attacked by. The two sides stop fighting when they discover their common cause and they leave to catch up with the Rigellians. She meets with the Grand Commissioner, who informs her of the desperate state they are in, and reveals the power of the Black Stars.
She approaches, under the Grand Commissioner's command, the Black Stars, and encounters a being named Avalon. Avalon battles them, but deems them powerful and courageous, and soon welcomes them inside. Avalon reveals he and his race are slaves, but that they can now attempt to fight back.
She remains behind with the Rigellians and Silas Grant as the Asgardians leave.
She attempts to harm Kragonn, but he and the Rhunians are veritable giants to them and take little notice. They defend themselves from more of the Protectors. They bide their time until Kragonn listens to them and realises the Rhunians don't need to gather energy and cosmic debris, for the rest of the Black Stars are dead planets. Thor and his band leave and the Rhunians stop destroying solar systems.
