Trini was working out at Ernie's Juice Bar & Gym along with her friends. Suddenly the ground began to shake and Trini and her friends were transported to the Command Center. There awaited quite the sight, a blue head floating inside a tube. And even more incredibly, this being called Zordon, had selected them to become Power Rangers. Kimberly and Zack blew Zordon off, but Trini, Billy and Jason lingered. The idea of protecting people from the evil witch Rita Repulsa appealed to the gentle and kind nature of Trini. With the others calling them, Trini, Billy and Jason left the Command Center. Outside the building they were confronted by another strange sight - putties. Trini fought with all her might, but the putties were too strong. Without hesitation, Trini activated her power coin and became the first Yellow Mighty Morphin Power Ranger. Needless to say, after morphing into a Ranger, Trini made quick work of the putties. Trini found herself falling for a new guy by the name of Richie. Although she was always casting loving looks towards him and inviting him to various functions with her, Richie seemed not to notice. He eventually became smitten with Trini, and they started to date.
