One plot idea for a snake summon Naruto fanfic is that there is a prophecy about a chosen one who can fully control the snake summons.

One possibility is that the reverse summoning is part of a secret jutsu gone wrong. Gojira's arrival might disrupt the balance of chakra in the Naruto world.

Well, one possible plot could be that Naruto, in his focus on other things like becoming Hokage and protecting the village, completely overlooks a powerful god - like summon.

This could then lead to Naruto having to face the consequences of his neglect and find a way to make amends with the summon.

She might then try to communicate with the snake, believing it to be a magical or intelligent being in the world of the fanfic.
