The five songs Sheik plays while doing a strong attack is the "Serenade of Water", "Bolero of Fire", "Song of Storm", "Nocturne of Shadows", and "Prelude of Light" from Orarina of Time.

An earlier design of Link featured him wearing silver armor, similar to Zhao Yun's design from Dynasty Warriors 6.

In contrast to Impa's samurai motif, Shiek's design is largely based on Ninja iconography. Also, many of the character's harp combos are inspired by Cai Wenji from Dynasty Warriors.

The "Under Siege" musical theme appears to be based on part of Gustav Holst's "Mars, the Bringer of War" suite from Opus no. 32 "The Planets", this is appropriate due to the heavy war theme of the game and the situation the characters are in when the theme plays.

Impa's armor was stylized with a Japanese motif. Early concept art shows that Impa's was conceptualized as a samurai, having the Naginata as the main weapon, as well as design elements from her Skyward Sword incarnation.

Many of Impa's moves and combos are likely inspired by the bodyguard/protector characters from Dynasty Warriors, Samurai Warriors, and Warriors Orochi. Her victory sequence with the Blade may also have been inspired by a move done by a character in Dynasty Warriors 8.

The character Linkle was originally created during the development of Hyrule Warriors. She was originally conceived to be Link's younger sister, but the idea was scrapped due to Eiji Aonuma not wanting her inclusion to conflict with Wind Waker Link's sister Aryll. After the game's release, sketches of her concept were included in the boxed editions' visual databook and she escalated into popularity within a portion of the Zelda fandom. Despite being incomplete at the time, she was one of the popularly requested characters during the open call for playable candidates posted onto the game's Twitter. When re-pitched to Aonuma with a revised backstory, he approved her.

Former Nintendo localizer Chris Pranger stated on his Twitter that Linkle was the last character he wrote before leaving Nintendo. He expressed excitement for her debut, adding that he liked writing for her more than he did Lana.

Link's design and moves in the game are heavily influenced by the character Zhao Yun from the Dynasty Warriors series. Both are clad in green, wear long scarfs, and are the main heroes of their respective franchises. Many of Link's iconic moves are based on Yun's combos.

Impa's armor was stylized with a Japanese motif. Early concept art shows that Impa was conceptualized as a samurai, using the Naginata as a main weapon, and used design elements from her Skyward Sword incarnation.

One of Link's unlockable weapons is the 8-bit sword and shield, which are based off of the sprites for the wooden sword and shield from The Legend of Zelda on the NES. However, the shield has been edited, the Christian cross on the original sprite for the shield has been replaced with four squares in the center, possibly to avoid religious controversy.

Darunia's victory sequence is a reference to The Legend of Zelda: Ocarina of Time, where Darunia dances happily when Link play Saria's Song.

On page 246 in the Hyrule Warriors Japanese Art Book there is concept art depicting Link's shield having some sort of spirit who would work as Link's partner.

Another piece of concept art shows that they might have absorbed the blood of enemies Link cuts down, although the precise details are unknown.

Eiji Aonuma stated on Miiverse that he felt sad that Midna's beautifully designed true form character would make such a minor appearance in Twilight Princess. He claimed he was happy to see Koei include her in Hyrule Warriors, as he had always wanted to have an excuse to have her appear in another Zelda game, but could never figure out how to do so due to the ending of Twilight Princess.

An early screenshot shows the Lizalfos enemies with the designs from Skyward Sword as well as a differently designed Heads Up Display.

Youske Hayashi had stated in an interview with Game Informer that both Zant and Girahim originally were not going to be playable. However, ##Tecmo Koei## ended up adding them to the roster in response to fan feedback.

Using the weapon switching glitch with Zelda using Lana's Summon Gate will cause her to hum her theme song while preforming a combo.

During Nintendo's E3 2014 Nintendo Treehouse event, Midna was shown having two separate weapon slots, hinting at her having an additional moveset, while in the final product she only has one. It is currently unknown why her second slot was removed.

There is a glitch in the game that allows players to swap weapon types with others characters.

There is a glitch when preforming Zant's combos. When his Special Power Meter is full and he performs a special attack right before an enemy's intro cutscene, the special meter will freeze and Zant will infinitely spin.

When Omega Force began making the game, it contained many core Zelda elements such as puzzle solving and an RPG approach. Shigeru Miyamoto intervened at this point, saying "this doesn't feel like a cross-IP game, this is more just like a Zelda game" and that if it was just going to feel like a Zelda game, there was no point in doing a cross-collaboration.

The game's producer, Yosuke Hayashi, stated that he is a huge fan of the Zelda series, and viewed the Hyrule Warrior's development process as making 'the official Zelda fan game.'
