Emerald Mckenzie Oliver was the 14-year-old sister of Tommy Oliver and Katherine Hillard, she was also best friend (might be girlfriend) of 16-year-old Justin Stewart who was adopted by Tommy and Kat because of the tragic death of his parents when he was only 10 years old. Despite their age gap, they were power rangers in the past who still have all their powers with the help of Billy and Alpha and Shadowhunters at night, all without Tommy and Kat knowing. They were actually from the year 2023 with the help of their magic watches that can help them possess any power they want. However, they had 3 powers (which are fire breathe, ice breath, and lightning from hands) because they were full angel blood. One day, they came across something that still changed their lives despite them experiencing it before.
