Spoiler:
Something ice-agish. Little cities... frozen land... storyline (with sad ending, tho'. Let's spice things up !) with Black (let's change the name and not rip Nintendo off... I know it's in Ranger 2... but how about Ice ?) trying to unfreeze the world. A myth about Heatran, who, together with Ho-oh, Moltres and Reshiram can change the frozen world into a normal once.
NOW THAT'S GANGSTA
