In some fanfictions, when Naruto loses control of Kyuubi, other villages might see it as an opportunity to attack Konoha. They may think that with Naruto out of control, Konoha is in a weakened state. This could start a whole new arc of conflict where Konoha has to defend itself not only from Naruto's unleashed power but also from external threats.
The consequences for Konoha's economy would also be significant. Rebuilding all the damaged infrastructure would cost a great deal of money. The trade within the village might be disrupted as well, since many of the shops and markets could be destroyed. Also, the ninja academy might have to be closed temporarily if it's damaged, which would affect the future generation of shinobi in Konoha.
The Hokage, depending on who it is at the time. They are usually very powerful shinobi. For example, if it's Kakashi, he could use his Sharingan and his vast array of jutsu to try and stop Naruto. He has experience dealing with powerful opponents and might be able to come up with a strategy to calm Naruto down or at least restrain him.
Yuki would definitely be affected. She has a close relationship with Zero, and his loss of control could put her in danger. Also, she would be emotionally distraught seeing Zero in such a state.
Sasuke might try to stop Naruto. Given their complex relationship, Sasuke would likely feel a sense of responsibility. He could use his own powers to try and subdue Naruto and bring him back to his senses.

Percy himself, of course. And his close friends like Annabeth would probably be there. She's always been by his side and would be likely to try and help him when he loses control.
