Blue

Blue is a young female Tarbosaurus who appears in "Journey to Fire Mountain" where she'll be the first one to defend Junior from danger in the area. Blue is an orange young Tarbosaurus with black stripes on her forehead, back and tail. And unlike the other female Tarbosaurus in the franchise, Blue has a unique blue streak on her forehead (underneath the black stripes) and another on her side of her head running down her sides to her tail. Despite being small and not ready, she's brave enough to stand up to bullies like Slash, also, she was shown to be the only one who's not afraid of him, she also teases Junior about his Tarbosaurus heritage, and she's very loyal to her friends and stands up for them if they can't do it. She was also playful, smart and even fearless. She presumably saw the new member, when a Slash came and tries to stab him with his claws, she will come and defend him which the Therizinosaurus disproves her interfering and tries to attack her until he is stopped by Blade. After they leave, the green tarbosaurus thanks her and he reveal his name to her, she reveals her name to him also and she wonders why didn't he fight him and teases him if he is a Tarbosaurus. But then the Deinonychus came, she runs but then realizes that Junior was standing still which she drags him to the others, after the Deinonychus were piling everyone, a Deinonychus picks out a victims along with another, one Deinonychus tries to find another one but looks where Junior & Blue are, Blue hopes they don't pick them but luckily neither of them weren't the target. Junior would ask Blue where they are going, but she doesn't know except whoever were the victims never came back and suggested not getting caught.
