Eva and Lexi Walters were twin sisters, and younger sisters to Sabrina Walters, a member of the Halloween Bandits. When they were five, Eva and Lexi developed a habit of stealing candy, which later ended up inspiring the Halloween Bandits. However, this caused their parents to put a no-sugar diet on the whole family, including their older sister Sabrina, which led to Sabrina co-founding the Halloween Bandits with her best friend Brianna and three other classmates. Eva and Lexi are both portrayed in Halloween Bandits by Maggie McKay.
