The Slime and The Omnitrix

With the events of the Hundred Year War over, peace reigned over the four nations, and the Avatar's Guardian is going to have a way more of a wild ride. With the power of a God known by LN73, (Y/N) (L/N) had his soul split apart along with Riley, both with the Omnitrix and the Nemetrix, and their split souls were sent to multiple other universes. With their power, talents, and skills, they can help in their new universe homes.

This universe takes place in the Tensei Shitara Suraimu Datta Ken, aka That Time I Got Reincarnated As A Slime, during the moment Ifrit takes over Shizu. As the battle was about to begin, a portal opens and both (Y/N) and Riley are shot out and land in front of the upcoming battle. How will (Y/N) and Riley react to a whole new world and with the problems that come with it? How will Rimuru react when both the Omnitrix and Nemetrix come into play? Find out in "The Slime and the Omnitrix!"
