Wind Waker: A New Disturbance
Helmaroc King first appears in the Wind Waker: A New Disturbance story scenario. It first appears under the name "Great Bird" and is part of the Great Bird's Forces Rogue Faction (of which it is the only member). The Monster Forces led by Boss Blin manage to drive it from its roost in Forsaken Fortress, causing it to attack the Hyrulean Forces led by Link and Tetra on Windfall Island. Tetra and Link can force it to retreat by attacking it, making it fly off. The Helmaroc King is essentially a distraction in the scenario and cannot be defeated, as the main focus is to defeat Boss Blin and the Monster Forces.
After the defeat of Boss Blin and the Monster Forces, Link spots the Helmaroc King in the sky with Tetra in its talons. Link rushes after the Helmaroc King to save Tetra.
Wind Waker: The Search for Cia
In Wind Waker: The Search for Cia, the Helmaroc King decides to roost in the Arbiter's Grounds located in Gerudo Desert. While it is resting, Tetra manages to sneak away and seeks the aid of Lana and the Hyrulean Forces, who had entered the desert to close the Gate of Souls that had opened up there. Eventually, the Helmaroc King awakes and tries to recapture Tetra, who calls upon Lana and the recently arrived Link to save her. They manage to destroy the Helmaroc King's Mask, forcing it to retreat momentarily. It soon returns, only to be killed by the combined might of Lana, Link, and Tetra.
The Helmaroc King fights primarily using its beak and talons. It can also wipe up whirlwinds with its wings and fire its feathers as projectiles. Like in The Wind Waker, the Helmaroc King's beak occasionally gets stuck in the ground when it pecks at its opponent, making it vulnerable to the Hammer and the Upgraded Hammer. Hitting it with the hammer while it is vulnerable will put the Helmaroc King into a downed state, causing its Weak Point gauge to appear, allowing the player to perform a Weak Point Smash. It can also be put into a downed state by hitting it with a Focus Spirit Attack.
