Emily Elizabeth Mendel II (birth name Sei-Gon and sometimes with the surname, Sparks) is an original character created by Vengie D for DC Comics. Here is a list of all the different iterations of the character. In Arrowverse-related media she is portrayed and voiced by Holland Roden.

Elizabeth Mendel/Mother Nature (Earth-1)
A recurring character in the Arrow-based "Guardians" series, and a main character in the "Central City Guardians" spin-off series. At first she's a normal girl, a reformed criminal trying to get her life on track until she meets Mark Mardon and appears in the first two seasons of Search for the Guardians. At the beginning of "CC Guardians" Elizabeth becomes a meta-human with Elemental abilities that goes by the codename Mother Nature. She is also revealed to be the lost princess of Drakonia and the one whom the Guardians are meant to protect, and wields the gem known as the Dragon's Heart. Elizabeth works at CC Jitters to support herself and her two children Josh and Jasmine Mendel. Her primary love interest is the seasonal iteration of Harrison Wells.
 * Wolf's Moon Rising: Elizabeth is a recurring character in the first season of "Search for the Guardians". She works as a barista/waitress at SC Jitters located in the Glades. She's shown to have a friendship with CNRI attorney Andrea Rayne, who helped her get an early parole for her arson charges. Throughout the series, she befriends Selena Merlyn, Tim Drake, Elena Queen, Thea Queen, and Rachel Rayne. Elizabeth also catches the eye of skilled bank robber Mark Mardon and begins a relationship with him that she keeps a secret from her friends. In every appearance, Elizabeth is seen wearing a dragon heart-shaped necklace with a small, purple gem (thus foreshadowing the fact she's the lost Drakonian Princess the Guardians are meant to protect). She has no idea of her heritage nor does she know some of her friends are the vigilantes protecting Starling City.
 * The Wolf, The Fox, & The Arrow: After the Undertaking at the end of the first season, Elizabeth decides to move to Central City with her boyfriend, Mark Mardon. She's only seen in a handful of episodes in the beginning. She's next seen with Detective Lorelai Snart of CCPD and S.T.A.R Labs employees Dr. Caitlin Snow and Cisco Ramon, when the four are attacked by Slade Wilson/Deathstroke. It's during this confrontation that hers and Lorelai's powers first activate, since they were both hit by a Dark Matter wave created when the S.T.A.R Labs Particle Accelerator exploded a few months prior. She's also revealed to be pregnant.
 * Guardians of Central City: Elizabeth is settling down in Central City, but her life is turned upside down when the S.T.A.R Labs Particle Accelerator explodes and awakens her inner Drakonian powers. During the first season she's a single mother to her twins (Josh and Jasmine) and a superhero going by the code name Mother Nature. Over the course of the first season she learns to manipulate the elements of Fire and later Electricity. Elizabeth forms strong friendships with her teammates Barry Allen/The Flash and Lorelai Snart/Ice Princess, as well as their support team Caitlin Snow and Cisco Ramon. She also feels a romantic attraction to Harrison Wells and becomes heartbroken when it's revealed he's the main villain the Reverse-Flash. By the end of the season, Team Flash becomes like family to her and her children.

After realizing that Zoom never truly loved her and just used her, she, along with her friend, Rory Ramon/Lady Flame, allied herself with her sister Elizabeth/Mother Nature and Lorelai Snart/Ice Princess to take out Zoom.
