Navi the Fairy

Navi the Fairy is a major character in The Legend of Zelda: Ocarina of Time. She serves as Link's guide throughout his adventure. She is regarded as one of the most annoying characters of all time by both critics and fans alike.

Why She Sucks

 * 1) She constantly bothers you when you are playing the game which can get extremely annoying, flashing Navi icon is also very distracting.
 * 2) She points out the obvious, like when you approach a door she explains how to open it.
 * 3) Most of her quotes like "Hey!" "Look!" and "Watch out!" are annoying and get repetitive fast.
 * 4) Throughout the entire game, she just keeps explaining things you already know, which is annoying for hardcore players of Ocarina of Time and is also pointless for her tell you what you already know.
 * 5) In the 3DS Version, she pesters you about taking a break.

The Only Redeeming Quality

 * 1) Her purpose gameplay-wise can be helpful at times, especially to new players. This can especially be handy when encountering new enemies, which she provides some helpful hints on them.

Trivia
Even though Nintendo has ditched Navi, They've made other sidekicks that are on the same level as annoyance as Navi. Tatl, Ciela, Fi, and Proxi.

In Angry Video Game Nerd Adventures, there's a fairy called "Naggi The Fairy" who is based on Navi's likeliness. The line "Hey, Listen!" has become an internet meme.
