Worst Things Marvel’s Kro Has Ever Done – Looper

After Zuras, leader of the Eternals, sacrificed himself to defend humanity against the judgment of the Fourth Celestial Host, the grieving Eternals returned to their home in Olympia. An elite force of Deviants had observed Zuras' death and took the opportunity to get the drop on the Eternals, rendering them all unconscious with brain mines.

Iron Man (then Jim Rhodes) was summoned to Olympia. Thinking he was a robot, Kro had his men attack Iron Man, but he gave them the slip. He then saw Kro atomize an Eternal, feeding his energy to the Deviant leader Brother Tode. Tode and the other Deviant elite hoped to gain immortality by siphoning off the Eternals' energy, which horrified Iron Man.

Rhodey then watched Kro unfreeze Thena from paralysis, offering to run off with her if she would leave this all behind. She refused, so he put her back under brain mine sedation, but Iron Man freed her when Kro left. Iron Man woke Thena up, but she was insane, nearly killing Rhodes and destroying his armor in a rampage before Kro put her down again. Rhodes managed to rebuild his armor with the help of an Eternal computer, and he freed the Eternals.

They made quick work of the Deviants and turned them into a single mass of matter, which they planned to dispose of in outer space. Thena spared Kro despite all that he did in nearly exterminating the Eternals, even if he did it under orders.
