Transforming into their respective Senshi form
Is the Genius Girl a Youma? Brainwashing School of Terror (Mercury)
In the manga, the first time Ami received her pen, she actually was seen using it for writing before using it for transformation. The Sailor Senshi sacrificed their pens, in order to awaken Sailor Moon, who was within Metaria at the time. These pens were eventually replaced by the Star Power Sticks.
First anime series
In the anime, Luna was the one who had gave Ami, Rei, and Makoto their transformation pens, while Artemis had given Minako her pen (though never shown on screen). All the Sailor pens had each Senshi's own planet symbol engraved on the cap.
Second anime series
- In the anime, all the Inner Senshi had identical transformation pens (except for the color and sign), but in the manga Sailor Venus had a different pen that came from her Sailor V times.
- The term "transformation pen" can also be used to refer to any other pen-type transformation devices.
