As Powergirl and the Starro possessed Captain Atom fought in outskirts, dust clouds rose from the increasing intensity. Kara initially had the upper hand, though Starro seemed to be becoming increasingly in control as It began to suppress Nathaniel's dogged resistance.
Using her heat vision confirmed her fear that extreme heat didn't affect Starro, if anything It thrived on the heat, increasing in size. She had to think. Her train of thought was interrupted by a shattering blow that catapulted her into the ground, as the dust cleared Kara was still on the ground.
Starro approached with a mix of caution and satisfaction, Its opponent Powergirl's breathing seemed laboured, heavy as her chest rose and fell, she was clearly injured enough to remain still while It prepared itself for replication.
Starro drew close using Nathaniel's body to pin Kara firmly to the ground as Starro's body grew and erupted additional tentacles as It prepared to replicate Itself, slowly It's bodies began to separate as the new Starro opened it's maw in preparation to possess the fallen Kryptonian.
The air by Kara's face grew cold.
" You will become one with me, like your mate. There is nothing you can do to prevent this now. As one of your amusing popular cultural gems puts it, 'resistance is futile' "
It chuckled once more in it's hissing manner.
Starro was now an inch from the apparently helpless Kryptonian, It's tentacles dripping from anticipation when suddenly the freezing blast from Kara's lips struck 'It' point blank, freezing the new Starro solid...
( Starro had a vulnerability to cold in the JLI story that kind of inspired this. I have taken that for my version and made it a much greater weakness, potentially fatal, while making him near impervious to almost any other physical form of attack )
