Naruto in another world
1st. Option:
Fighting with Sasuke in VOTE opened interdimensional warp gate that sucked him in, now stuck in terraria world he is trying survive and defeat Moon Lord thinking that would help him in some way come back. First I was thinking about Kaguya last F**K YOU throw him through a portal but then he would be to OP and wouldn't think about using things he could find in there.
2nd. Option:
Was execiuted by konoha for hurting sasuke 'too much' and before he died he promised that "even if I will have to fight angels or conquer the hell I will return and I will have my revenge!!". After his death he found him self in terraria world with he begin slowly conquering by defeating bosses and taking control over them and normal enemies. Later after he gain control of this world and learning everything he was able to open the portal to his old world and release these creatures on elemental nations (also coruption/crimson and hollow maybe also mushroom and jungle biome that begin spread ower the world).
