First appearance: Act 2

Sailor Mercury shoots a misty beam of water at the enemy.

Note: There was previously much debate about whether the attack is called "Mercury Aqua Mist" or "Mercury Aqua Beam", but Millie found a PGSM trading card that has "Mercury Aqua Mist" written out in katakana. I guess that's that debate over with.

Anime/Manga Comparison:
Sailor Mercury's first attack in both the anime and manga was more of a defensive attack than an offensive one - it involved her creating a cold fog which made it harder for the monster to attack. In the original release of the manga, this attack had no name. However, the rerelease of the manga has a name, "Mercury Aqua Mist", added when Sailor Mercury uses the attack for the second time. In the anime, this attack was called "Sab�o Spray". "Mercury Aqua Mist" in the live action series is very different to Sailor Mercury's first attack in the manga, which makes it seem odd that if you are comparing to the new version of the manga, they have the same name.

Previously I had mistakenly written that "Sab�o Spray" was the name of Sailor Mercury's first attack in the manga. Thanks to Mike for pointing out this mistake.
