Emily is a country girl who becomes a Ranger by chance. She is close to her older sister, Serena, who had been training to be the Yellow Samurai Ranger. When Serena became ill, Emily stepped up to take her place. Emily is deeply respectful of Jayden and wants to help the team in any way she can.

She has rather low self-esteem; she genuinely believes that she is clumsy and not fit to be a Ranger. Emily used an old saying "Sticks and stones may break my bones, but words will never hurt me" to help her get through her childhood. She can also be seen playing a flute, due to her sister playing a flute to make her feel better every time someone picked on her. She idolizes Mia and strives to become more like her. As the series progresses, she becomes more confident and braver and no longer doubts herself or her abilities.

As the Yellow Ranger, she is the Samurai of Earth and her personal weapon is the Earth Slicer. She pilots the Ape Folding Zord.

The Ape Disk allows her to use her signature move "Seismic Swing."

She can use the Black Box to access her Super Mode or the Shark Disk to access Shark Attack Mode. When piloting a zord she morphs into her Megamode form. She will morph into Super Mega Mode or Mega Shark Mode if she was in Super Mode or Shark Attack Mode prior to morphing. Using the Shogun Buckle she can access Shogun Mode.
