Naruto could potentially gain allies among the water - based creatures in the Naruto universe. With the trident, he could communicate or form a bond with them. However, he might also draw the ire of those who oppose any form of outside power or interference. There could be ninja clans or groups that believe Naruto having a weapon from another mythology is against the natural order of the ninja world. This could lead to new enemies who would stop at nothing to get rid of Naruto and the trident.
