Gray vs. Invel is the 498th chapter of Hiro Mashima's Fairy Tail. The battle between Ice Mages ensues, with Invel foretelling Gray that he possesses the darkness that in turn can make him become their comrade, when it eventually consumes his body. With Gray denying this, Invel goes to place an Ice Lock on both Gray and Juvia, inciting a battle to death between the two in order to break the Magic.
