Infinity Stones of Pangaea

Each of our heroes's Infinity Stones activates a Horn of Unicron in around the world of Pangaea. So, Optimus Prime and Superman have the Space Stone to activate the horn of North America, for example. Without the Space Stone, Shoutmon is vunerable to attacks from outer space. Terror and fear will strike if Unicron will be piloted if he is taken over by the forces of evil, like Megatron, the Wicked Witch of the West, and dozens of other evils from Pandora's Box.
