Sailor Mercury is the smartest of the Sailor Scouts and is also known as the technical whiz of the group. She employs the Mercury Bubble Blast as her special attack in battles. Mercury, otherwise known as Amy in her schoolgirl persona, is one of the quieter Sailor Scouts, but when she chooses to speak her words carry a great deal of force. Mercury is the most clear–headed of all of the Sailor Scouts and is often the one to whom the rest of the girls turn for advice.
