|~ Jerrica using her earring To transform herself into Jem.|
Jerrica Benton, also known as Jem (voiced by Samantha Newark, singing voice recorded by Britta Phillips) is the titular protagonist of the series Jem and the Holograms. Jem is the leader of the Holograms where she provides the lead vocals. She is the alter-ego of Jerrica Benton, owner of Starlight Music, and a foster home for orphaned or foster girls known as "Starlight House". Jerrica Benton inherited both Starlight Music and Starlight House from her late father Emmett Benton.
Using the power of Synergy, a powerful computer with holographic capabilities, Jerrica can become Jem by touching her special star-shaped earrings (the "Jemstar earrings"). Most stories of the series consist of Jerrica hiding her identity from others, especially Rio Pacheco, her long-time boyfriend. Synergy's holograms are integral to maintaining the illusion that Jerrica and Jem are two different people. Jerrica tends to compartmentalize her life in some respects and even occasionally shows jealously toward the alter-ego of Jem she created. Her birthday is revealed to be June 1 in the episode "The Fan".
