It is at that moment that I have a realisation. The universe wipe might've destroyed my Magikarp, but there would always be more. Magikarp were natural survivors! Quickly bringing myself back to the Pokemon world, I dive to the depths of the ocean, where I come face to face with a shiny Magikarp.
Throughout many months, I gain the trust of the Magikarp and its colony, and eventually the wider Magikarp community. I learn their ways and eventually convince them to join my on my grand journey to conquer the universe. My Magikarp empire spreads throughout the newly-born universe and conquers every planet in their galaxy, and move outwards even quicker. But it all comes to an end after many millennia of rule, when a group of planets rise up and my Magikarp empire is forced to retreat, breaking apart as I seemingly disappear and the rest of the Magikarp fight among themselves for power.
Little did they know that I simply was using the resources of my empire to create a functional time machine, a massive Gyarados ship that could warp through time and space. Arriving back at your house with a ship full of the most powerful Magikarp warriors in dozens of dimensions and times, I fire a laser that razes your house to the ground.
My elite group of Magikarp and I then exit the ship, take the briefcase, and then use the ship to escape.
