Number Seven is a member of the Robot-Fighting Ring.
Seven is housed in a blue/purple chassis with a large "07" on the side, hence the name.
She is frequently afraid of Faye Whitaker's repair efforts, and flinches constantly during buffing - much to Faye's annoyance.
More than once Number Seven has accused Faye of being a robot, due to vibrations coming from her pants. Faye insists it was a cell phone.
She had long held feelings for Jeremy, and they are now in a relationship.
She designed the sign for Faye and Bubbles' new shop, Union Robotics.
