Meg

Meg is a character in. She is one of, and the eldest, of the four Poe Sisters.

Ocarina of Time
In, Meg appears along with her Sisters in the Forest Temple. She appears after all of her other Sisters have been slain and their respective torches lit, and uses the Temple's main room as her battleground to fight Link. Her battle technique is vastly different from her Sisters; she replicates herself into three other clones and begins to spin around Link. Mistaking the true Meg for an illusion will cause the fake to disappear, giving Meg a chance to inflict damage. Although her technique is intimidating, her true form is easily recognizable - the real Meg will be the first to spin around once the four "Megs" have surrounded Link. Meg can be struck by Link's Master Sword, slung by Arrows, as well as pierced by the Hookshot. Four strikes on the true Meg is enough to dispel her and light the final, purple torch in the center of the Temple. Meg's death and the lighting of the four torches will enable Link to access the Temple's basement, where the Temple's boss, Phantom Ganon awaits.

Majora's Mask
In, Meg appears along with her three Sisters at the Spirit House in Ikana Canyon. Link can battle all four of the Poe Sisters to earn a Piece of Heart at the cost of 30 Rupees. Here, Tatl identifies Meg as the eldest of the Poe sisters.

Oracle of Seasons
In, while the Poe Sisters of Explorer's Crypt are left unnamed in the English version, one of the sisters is similarly named Margaret in the Japanese version, and appears alongside her sister Amy. She carries a lantern, leaving a trail of fire as she flies around. Each of the sisters are first seen in rooms that gradually darken, eventually casting Link back to the dungeon entrance if he is too slow to flee the room. They then appear in rooms next to the room they had cursed, where Link fights one of them. Finally, they fight together, forcing Link to not only attack them, but also relight the lamps they extinguish, lest he be expelled back to the dungeon entrance.

Trivia

 * Before Meg's battle in Ocarina of Time starts, she appears to be crying. This may be because her Sisters were all defeated, hence she reveals herself after her Sisters have perished.
