Gia Moran is Megaforce Yellow, the Yellow Ranger of the Mega Rangers. She is portrayed by Ciara Hanna.
Gia is one of the five teenagers chosen by Gosei to save the world from the Warstar Aliens. She first fights alongside her team against Scaraba.
One day, she and Jake Holling flirted with each other. When they saw alien ships capturing humans, they decide to follow the ships in one location and call the other Rangers to help them. After the battle, Jake complimented Gia about how good they are as a team. A week or so later, Jake and Gia gained access to the Land Brothers Zord.
Later, Gia and Emma are turned into worse enemies by Queen Beezara. When the two were reminded by the Rangers they were friends, they broke free from the spell and defeated Beezara.
During the Armada's invasion, she and Jake return to the Command Center (Megaforce). Slowly the other rangers return to the CC, and Gosei presents them with the Super Megaforce powers.
Gia Moran is labeled as 'Miss Perfect', and it's hard to argue with that. Pretty, personable, strict, and a powerful martial artist, Gia is as intelligent as she is confident. She's been best friends with Emma since they were little, and that's not going to stop just because they're in different social cliques now. The Yellow Ranger's constant success can be frustrating to her teammates, but she and her Tiger Zord are dependable to the end! She developed a crush on Robo Knight when he first appeared.
