Chrysta

Chrysta was a mechanism created by the Dominion and Greed Corps. It was implanted in the Solar Core Harvesting Facility within one of the two suns of an unnamed planet, and sustained the facility using Samus Aran's stolen Ice Beam. It separated the sun's core into frozen chunks, causing the sun to stop giving heat to the planet and destroying its agricultural industry. When Samus investigated the facility and discovered Chrysta, it revealed that it was one of Greed's Deadly Six Stars and explained that if she destroyed it, the facility would melt since Chrysta's ice abilities maintained it. Samus took a risk, and Screw Attacked Chrysta, destroying it. She quickly recovered her Ice Beam and worked with Joey Apronika in tandem to escape the facility intact.
