In 1989, in the tale "Christmas with the Super-Heroes" the soul of Kara appears to Boston "Deadman" Brand, cheers him up, and then disappears from continuity until 2001 (see below).
A hero resembling the Pre-Crisis Kara would later appear in Final Crisis: Legion of 3 Worlds #5, along with an entire army of Legionnaires gathered from alternate worlds, times, and realities, to battle the Time Trapper.
