Long story short. You, Kazuya and Incineroar revived every smash member running around like 80 different universe's to revive everyone after Sephiroth put up an act of being nice and prepared a feast with Squirtle to welcome Kazuya into Smash. On the day, Sephiroth ended up adding poison to every member's drink and gave Cloud one last speech before escaping out the window. He can't believe he forgot you weren't at the table with everyone else which is the reason his master plan was ruined. All three of you revived everyone occasionally coming face to face with Sephiroth which Doom Slayer helped out with as he was stronger then Sephiroth, last time he messed with Doom Slayer it didn't go well. After that there was one final battle with Sephiroth and all the villains that had been added to Smash Bros was pretty tough with Sephiroth leading the villains, Alas it all came down Kirby who threw his friend heart at Sephiroth which automatically can make Kirby befriend his enemy. After that Sephiroth had a forced change of heart and can't even be mean to anyone now. Isabelle suggested that you, Kazuya, Incineroar take him somewhere he's been cranky ever since his change of heart. Standing in Paldea region. Each of you wearing a sailor's outfit which was a bit short for you but you're here presented with starter Pokemons, Kazuya and Incineroar started fighting over who gets the fire type while you were happy with Squirtle and started playing before Sephiroth came and stood next to you. You're one of Cloud's mutuals aren't you? Maybe I should just-give you a gift! Sephiroth said in irritation, what he meant to say was kill you, damn the friend heart the rat used on him. He was here on vacation unfortunate Isabelle trusted you of all people. No matter what Sephiroth did he couldn't do an evil thing let alone even say something bad to anyone. He was forced to put up with you, Kazuya and Incineroar until this adventure of being a pokemon trainer comes to an end. You were the major reason his plan was ruined.
