Possessed Zelda

Possessed Zelda is a recurring boss in  series, first appearing in Twilight Princess.

Twilight Princess
Ganon's Puppet Zelda is one of the final bosses from Twilight Princess. Ganondorf uses his power to turn Zelda into his puppet to fight Link when the two meet at Hyrule Castle. She has three core attacks:

She will dive at Link with her sword extended. This attack can be either blocked with the shield or dodged with strategic rolls, jumps, or strafing techniques. Secondly, she will make a triangle of light appear on the floor. Link should quickly leave its area of influence the moment it materializes to avoid damage.

Finally, her third and main attack consists of an energy ball which Zelda will fire at Link. This attack is the only method in harming her. Link must rebound the energy ball back to her by swinging his sword or empty bottle when it is near. Continue to volley it back until it finally hits Zelda.

There is also another strategy: using the Jump Strike. While she is readying the ball, Link must get underneath her and charge up his jump strike. As soon as she launches the ball, use the jump strike. It will be in such close proximity that it will almost guarantee a hit.

After hitting her about three times, Puppet Zelda will be defeated, and Midna, with the help of the Fused Shadows, returns Princess Zelda to normal.

Spirit Tracks
Princess Zelda's body is involved in the second-to-last boss fight of the game as the Possessed Zelda, where the princess's body is inhabited by the essence of Malladus, the Demon King. This fight takes place on the roof of the Demon Train within the Dark Realm as Link and Zelda seek to reclaim her body and stop the plots of Chancellor Cole and Malladus.

In this fight, Cole floats around the roof of the train attempting to take control of Zelda's Phantom body by sending demonic rats to attack her while Malladus awaits at the head of the train, sending lasers streaming toward the pair. To best the evil duo, Zelda, possessing a Phantom, must lead the way as only her armored body is strong enough to repel Malladus's laser attacks. Link must keep Zelda moving toward the head of the train to where her possessed body awaits, all the while protecting her from the demonic rats Cole unleashes as he attempts to prevent Zelda from reaching her body.

In the event of Zelda coming into contact with one of the rats, Link must use the boomerang to cut the evil puppet-strings Cole uses to control her like a puppeteer by sending it flying behind Zelda to cut the strings. Once Zelda comes into contact with her body, she will seize Malladus and the two will float off around the head of the train. Link must then strike Malladus truly with an arrow from the Bow of Light to purge Zelda's true body of Malladus's essence, ending the fight.

Trivia

 * While fighting Zelda in Twilight Princess, you can clearly hear both the Song of Time and Zelda's lullaby from Ocarina of Time in her battle theme.
