Phantom Aqua

"Only your heart is hollow enough to be a demon's."

- Phantom Aqua to the real Aqua.

Phantom Aqua is a boss in the video game Kingdom Hearts 0.2: Birth by Sleep - A Fragmentary Passage, the ninth game in the Kingdom Hearts series. She is a dark copy of Aqua that she encounters in the Realm of Darkness, and a physical manifestation of Aqua's insecurities.

History
When Aqua arrives in the remnants of Dwarf Woodlands, the Magic Mirror brings Aqua's reflection to life, and she pulls Aqua into the Mirror. Inside, Aqua goes through areas inside several other mirrors, and battles the Phantom Aqua three times. After the Phantom Aqua is vanquished, the real Aqua proceeds on her journey.

A stronger version of Phantom Aqua appears as a post-game secret boss.

Powers and abilities
Being a doppelganger of Aqua, the Phantom Aqua has all the same abilities as she does, even wielding a copy of the Master's Defender Keyblade. She has the ability to teleport and to create copies of herself, as well as to summon large ice crystals to attack. She can also use the real Aqua's Spellweaver Command Style.
