Lemon Zest is the wild, obnoxious rocker girl of the Shadowbolts. She could always be used to seeing her rocking out with her headphones on. She wears the Elec Armor, allowing her to use electricity at her own will. She had a good bond with Volt, especially during the times of revealing his past of Barrys murder of his own father. After he left, Lemon made it apparent to keep using her Armor for good.
Her armor also comes with a secondary mode, Elec Divine, by equipping a Deck with the Divine Guardians flag. In this mode, she can use Electricity and Light based attacks, and also gain flight capabilities.
Even though she passes it off as a joke, Lemon is deeply in love with Volt.
