CoD Zombies Fans: What Would Happen If...

[Cherry Pop 15]

(I apologize if this isn't the right place to post this. It's not technically off-topic as it's still related to MLP, so I figured this'd be fine.)

For those familiar with the basic CoD Zombies story, I wanted to speculate on something with you. What would happen if the Apothicons had hidden the MPD on Equestria's moon rather than Earth's, and had sent element 115 to Equestria? I only have two things to say on the matter, but I'm curious what else could be added to it:
 

• The Apothicons had sent element 115 to Earth in the hopes that Humans would begin to use it to wage war, thus opening a gateway for them to enter. Obviously, Equestria wouldn't use element 115 to wage war... so what would they do with it, and what would be the result?
   
• Luna/Nightmare Moon would discover the MPD upon being banished there. What would happen from there?
