The whereabouts of many Rangers
The Ranger in question is Power Rangers Dino Charge Red Ranger Brennan Mejia, who even has a title and everything picked out for his character's future.
"You guys familiar with The Flash? So you know how he can go back in time and stuff? Well apparently I can do that too if I have the other Energems," Mejia told fans at the Power Rangers panel at Yestercon (via Steven Alvarez). "So I think Tyler...I'm making this up because I don't actually think this (laughs), he wanted to protect everyone because you know everyone's still working at the Dino Bite Cafe flipping burgers, but he wanted to keep protecting people. So I think he went back in time and recruited a bunch of himselves, and then just made like a Forever Red part 2. I'm titling this!"
It's certainly an interesting theory, and as you can tell by the crowd reaction to his story, fans would love to see a sequel to "Forever Red", even if it did just include 10 versions of Tyler Navarro.
Mejia played the role of the Red Ranger in Power Rangers Dino Charge and Dino Super Charge. Originally his quest centered around finding out what happened to his father, who vanished during an expedition. He used the notebook his father left behind to try and find him, which brought him to Amber Beach and eventually in touch with the Energems.
He would eventually discover the fate of his father, James Navarro. His father came upon the Aqua Energem 10 years before, and to protect his family from the enemies that would bring he hid in a cave, isolated from everyone aside from his friend Rusty. He would come out of hiding once he discovered Tyler had an Energem of his own and would fight by the Rangers' side as the Aqua Ranger.
Both would return for Power Rangers Dino Super Charge as well.
