After chasing off Boomtower and defeating Draknarok, Javi and Izzy were introduced to Solon by Zayto. Izzy later starts training for an upcoming cross-country race with her cousin Lily coaching her and Javi watching her. The rest of the Rangers arrive to see Izzy as she introduces Lily to them, revealing that the latter has CHARGE syndrome, and is a Special Olympic medal winner for finishing first at the 1500-meter track races as well as being her coach for her race. When the Rangers return to their base, Solon reveals that she managed to find the location of Izzy and Javi�s Zords. Since they were buried underground for millions of years, Solon says she built a device in order to find them. Izzy gets set right before the race. When Izzy finishes her laps, she was not happy to see Lily arrive late as the race was tomorrow and was even more upset when the latter explained that she had to help her friend Mona do some shopping.

On the day of the race, Izzy learned that Mona was on a wheelchair, which made Izzy feel guilty. At the start of the race, she was confronted with her rival, Fern, but she's soon able to pull into the lead. Izzy continues the race until she sees that Fern trips on a root and falls into a pit. Izzy decided to go down and help Fern, even though she will lose her lead. She was also prevented from joining the race after following the foes. Izzy saw that her Dino Fury Key was resonating strongly to her Zord. Izzy morphed and attacked Boomtower, but the villain soon left. Izzy finds her Zord. Izzy calls them and tells the team to lure the Sporix Beast to her location and have him destroy the mountain containing her Zord. The plan works as the monster destroys the mountain and frees Izzy�s Tiger Claw Zord. The new Zord easily overpowers the beast before Izzy combines it to form the Dino Fury Megazord Claw Formation, beating the Sporix Beast. Javi later encourages Izzy to finish it, even though she will end up in last place. Izzy apologizes to Lily for the way she treated her. The Warden also appears to tell Izzy that he is proud of her. When Tombtress shot Javi with a Mood Blast that made him emotional, Izzy revealed the last time he was like it was when they lost their pet goldfish, he was fond of. When she was hit herself, Izzy became extremely scared to the point she didn't want to fight.

Izzy continues to see Fern after the race. Around this time, she also decides to see a new coach and quickly leaves after learning that the coach cares only about money. Izzy ultimately fell in love with Fern, who shared her love as the two began dating. When asked by Fern to be her date to prom, Izzy's mom, Rina, decided to design the outfits, only to become extremely frustrated when Javi gave it to her and revealed it was a dress before throwing it out. Upon learning the dress was for Fern, she recovered it and clarified the situation to her mother before they decide to make a new one together. Learning Fern is going to Oakdale College, Izzy expressed her joy while secretly keeping the fact she declined her invitation until Warden Garcia found out and told her off, in front of Fern. Learning she was leaving early, Izzy caught up with Fern to express her love as well, which Fern hadn't said to her, but did, through her Ranger identity. Realizing Izzy is the Green Ranger, they kept it discreet before Fern got on the bus, wishing the power to protect her.
