Naruto beats madara at the battle of the end and seals the incomplete juubi(minus kyuubi) into himself using a seal that causes the incomplete juubi to merge with him fully so he won't loose kyubi who has been kind and has loved him his entire life. This essentially makes him the new juubi, and gains the juubigan(his icon thingy) and immortality, as well as mastery over all jutsu and the ability to turn others into demons like him. He realizes that the people of his world will never respect him or with the exception of two women(tsunade and anko, cause they're his favorites), ever love him. He decides to take them and leave to another world. He travels to the Pokemon world. Using his power he turns tsunade and anko into demons and, upon discovering about Pokemon trainers he reduces anko and tsunades age(which no longer matters due to the wonders of immortality) to his so they are the same age. They then set off on a pokemon adventure through all the countries, starting in kanto, eventually he works out a seal based off pokeballs to create a special pokeball that is all white with the shiki fujin around the button so that kyubi can get out of him. She has all her bijuu abilities(bijuudama included, have to be able to deal with pissed off legendaries some how) and several jutsu in place of pokemon moves and can change her size from normal giant size to the size of a ninetails, and any where in between, along with being able to turn into a human to...spend time with naruto. Her size affects her attack power and she is classified as a legendary. The other places on his team are open to the author s choice, and not limited to six, but must be under 15. His adventure can take the place of ash' s, or ash can be a girl and join narutos journey and harem. Harem is open to the authors choice except for tsunade and anko, and possibly fem ash. Adventure can follow pokemon Canon or not. Naruto is smart and badass. Bashing up to author
