1. Freddy: The Final Destination (Nightmare on Elm Street/Final Destination)
Imagine, if you will, that the teenagers of Elm Street are due to head off on a school trip. Low and behold, prior to embarking, one of them has a vision that they would suffer a horrible demise in an accident if they go through with the trip, which results in several of them heading home to Elm Street. Death, angered by his plan being interrupted by one student's premonition, starts picking them off in the order that they were meant to die in the accident. Freddy is not pleased by someone else killing 'his' children and starts to murder them before someone/something gets there first. This, in turn, angers Death, who is NOT happy that these teenagers are being killed in the 'wrong order' and decides that Freddy must die. But, in order to face off with Freddy in the Dreamworld, Death must become more than just a malevolent presence. Death reveals his tangible, physical form and tempts Freddy in to his dreams where the two face off in the battle to end all battles. So, what do you think? Would these make for enjoyable crossovers? Can you think of some of your own? Let me know in the comments.
