While the Horde leader has the power to bring all the demons back, his greatest power is in manipulating the divisions separating the Heroes. The only way to bring down the evil is to give their powers willingly over to one member of the team. But, with the group split seemingly beyond repair, joining their superpowers for one last epic clash may prove impossible.
