The brothers (along with Sonic, Ash and Co.) travel back in time to retrieve Princess Peach, only for the Mario Bros to come face to face with baby versions of themselves, the princess and Bowser. Teaming up with their younger selves will soon send Mario, Luigi and Co. on a quest of lunatic proportions (Mario & Luigi: Partners in Time and Pokémon belong to Nintendo, Sonic the Hedgehog belong to SEGA).
