Green lantern's hometown
Injustice comic[]
During the start of The Regime, they had control of Coast City, and when the Green Lanterns tried to stop Superman, many died during the battle, including Ganthet. What happened after is unknown.
Injustice 2[]
Coast City was one of the cities captured by Brainiac, but like Metropolis was deleted and presumably killed all of the inhabitants, including Carol Ferris. It was also briefly mentioned by Superman when he tried to make him join again.
