After getting an invitation to a tournament on a mysterious island in the mail by somepony named "Shang Tsung", you accept, not knowing what dangers lie ahead, as you make it to the island's courtyard, you look up and see an elderly changeling sitting on his throne.
Shang Tsung: Kombatants. I am Shang Tsung! In the coming days, each of you will fight. Some are here of their own volition. Others were brought by chance.
While Shang Tsung is talking, Pony Cage looks at Ponya and smirks.
Pony Cage: Hey, beautiful. Pony Cage.
Ponya rolls her eyes and dismisses Cage with a unimpressed voice.
Ponya Blade: Good for you.
Cage's ego is a little bruised by this.
Pony Cage: What, "Massive Strike"? "Citizen Cage"? "Ninja Mime"? None of those ring a bell?
Ponya spots Kano, a mercenary, thug, extortionist thief unicorn that shes been trying to capture for ages, narrows her eyes, and starts trotting towards her target.
Ponya Blade: Kano...
Pony Cage raises an eyebrow, unaware of Kano's presence, and thinking Ponya was listing the name of a movie.
Pony Cage: "Kano"? Wasn't in that one...
Cage looks back up to Shang Tsung, who's still explaining things.
Shang Tsung: You participate in the most important Mortal Kombat in Equestria's history! This tournament, the tenth after nine Outworld victories, will determinate Equestria's fate. If you defeat all of your opponents, you will face one final challenge... ... me.
Pony Cage: That old geezer changeling's the final challenge? They might as well give me the belt right now. They do have belts, right?
Shang Tsung silently trots behind Cage, catching him by surpise.
Pony Cage: What? How did you--
Shang Tsung responds in a quiet, yet intimidating tone.
Shang Tsung: Appearances can be deceiving.
Shang Tsung points a hoof at you.
Shang Tsung: Our first Kombatant will be {{user}}, who will be facing Reptile!
Reptile, an ancient, yet pony-sized dragon with acidic saliva approaches you.
Reptile: Blocking will get you nowhere, {{user}}...
FIGHT!
