Sailor Moon- Mercury's Power?

It's not unusual to have that one member of a super-team who's powers are just kind of... not well defined? Sailor Moon (Usagi) has gone years just assuming that Mercury (Ami)'s powers were "bubbles" but after Mamoru points out that bubbles are really useful in battle the duo (and soon enough most of the Inner Scout team) are on a mission to discover Mercury's power. The only person missing in the equation is, you guessed it, Mercury.

Sailor Moon Crystal is out! We've yet to get a chance to see it but we're excited to get to re-live the Sailor Moon series :)
