The fanfiction might expand the social and political aspects of the Naruto universe. If a new and powerful chimera bloodline emerges, it could shift the balance of power among the villages. This would lead to new alliances and rivalries. For instance, a village with a chimera bloodline ninja might become more dominant, causing other villages to either form alliances against it or try to steal the secrets of the bloodline. Also, it could introduce new clans or groups related to the chimera bloodline, which would further diversify the Naruto world's demographics and power structures.
Often, characters who are hybrids of different bloodlines tend to be popular. For instance, a character who is part Uzumaki and part Senju could be really interesting as they would potentially have access to both the Uzumaki's life - force and sealing abilities, as well as the Senju's natural affinity for all types of ninjutsu.
