Rayo Negro
Medusa appears alongside Black Bolt in issue #1 of the "World War Hulk" series. Medusa is seen with Black Bolt when Hulk attacks Attilan. She warns Hulk not to pursue a fight with her husband, as Black Bolt has defeated Hulk in past battles. The fight begins and Medusa is not shown to interfere or assist. Black Bolt is subsequently defeated by Hulk, though the battle is not shown beyond Black Bolt's opening attack and it is made unclear as to how Hulk managed to win the fight.
