Defenders of the Earth (1986)

S1E37 The Frozen Heart

Ming's army captures LJ's girlfriend, Kate, transforming her into a Frost Person to deceive LJ, Rick, and Jedda into surrendering the Defenders' Space Station, now equipped with a deadly laser-cannon, to him. After the Swordship is downed, the adult Defenders activate the Space Station's self-destruction sequence. However, after surviving the crash, they discover that Rick, LJ, and Jedda are still aboard. A frantic scramble ensues as they race against the clock to disable the self-destruct mechanism before it’s too late.
