Legion of Superheroes #47 (1989)
Having defeated their dead comrades, the Legion arrives at Mordru's palace and is confronted by the resurrected Nemesis Kid, Dr. Regulus, Jungle King, Zaryan, Charma and the Dominator ambassador to Earth. Even if they survive this new threat, will the Legion be in any shape to take on Mordru himself? The penultimate chapter of the 'Mordru Rises' storyline ends with someone being buried alive...but it's not who you might think. Written by Tom Bierbaum and Mary Bierbaum, with art and cover by Stuart Immonen and Ron Boyd.
