Alyssa is feisty, kind, clever, and polite with a sense of humor.
Alyssa is the kind, nurturing member of the group. When any Ranger is injured, she is right there tending to their wounds. Alyssa tries to diffuse any tension between team members. Being a kindhearted young woman, Alyssa often is in the position of peacekeeper.
In the early days of the team, Alyssa tried to keep peace between Cole and Taylor who would have conflicting ideas on what was best for the team. She would cook for them and even read stories to Danny and Max, the Black and Blue Rangers respectively.
There have been a few hints that Alyssa may have a crush on Cole, however this is unconfirmed. When Alyssa wasn't fighting Orgs, she stayed active by riding her bike to school and taking dance classes at Turtle Cove University, where she has a scholarship for perfect GPA.
Alyssa was trained in the martial arts by her father, who is a renowned martial arts instructor. He intended for her to eventually take over running his school, and was heartbroken when Alyssa decided to move to Turtle Cove and attend Turtle Cove University. One day when he visited his daughter, he was proud to discover that not only was she a Ranger, but she had excelled in the martial arts he taught her. As a result, he accepted her decision to continue her education.
She later helped Cole find out about his parents' death by cross-referencing his picture.
She was involved when the Wild Force Rangers teamed up with the Time Force Rangers, and she battled the Putrids alongside Jen; the Pink Time Force Ranger, using the Chrono Blasters.
When all the Orgs were defeated, Alyssa was relieved of her life as a Ranger. She finished college and became a kindergarten teacher. In the last episode, she is seen telling her story to her class in a fairy tale fashion, making her the narrator of the season.
- Alyssa is the second Female White Ranger after Delphine and is followed by Udonna and (arguably) Kat Manx.
- She mostly called Toxica by the term of Grandma which Toxica hated. Since Toxica never told her age to anyone.
- Originally while she is a school teacher at the end of the series, she was also going to be marry to Cole Evans.
