Double Bubble: Attacks
Mercury Power, makeup!: Ami says this to transform into Sailormercury, senshi of Wisdom.
Mercury Star Power, makeup!: Ami says this to become Super Sailormercury.
Mercury Crystal Power, makeup!: Ami says this to become Sailor Starmercury.

Shabon Spray (Mercury Bubbles Blast): Mercury's first and weakest attack. Essentially just creates a fog.
Shabon Spray Freezing (Mercury Ice Bubbles Freeze): The same thing, except it may temporarily freeze an opponent.
Double Shabon Spray
Shine Snow Illusion (Mercury Icestorm Blast): A snowflake version of Aqua Illusion.
Shine Aqua Illusion (Mercury Aqua Illusion): In the anime, it almost looks like Shabon Spray Freezing. It also is the most named attack in the NA dub, barring Jup's Oak Evolution.
Aqua Mirage: ???
Aqua Rhapsody: This is where Merc's famous harp comes in.
Mercury Aqua Magic: As you can tell by the name, an anime attack. I think it looks cool.
Hyperspace Area Formation: an only-manga attack.

Sailormercury in any guise also has her minicomputer and her visor. In the manga, Sailormercury also has a headset, but only in the first season. (You never see it again after she powers up.)
