Alright I may need to figure out how this is going to work, at least in origin of her powers. The backstory isn't much of a problem, daughter of a wealthy Japanese family whose business booms in America, but she isn't much for just sitting around and being pretty all day. But when it comes to becoming a Super Sentai it's a bit awkward.

In canon she, and the other Kyoryuger, are picked by an ancient bird themed alien for their great bravery in order to face other evil aliens that want to steal emotions to ressurect their beast of a master. But to prove worthy of becoming Kyoryuger they have to defeat their pre-requisite Sentai giant robots in honorable combat, to show they have the bravery to be partners with them. Therein lies the problem-these are just roboticized dinosaurs that fought besides bird-guy that have existed for millions of years waiting for the evil aliens to attack again...because the evil aliens are what killed the dinosaurs, with anthropomorphic versions of extinction level events (disease, the ice age, and metors). So that may be a slight issue. I'm wondering how to get around that.
Both because I'm unsure where a sentai robot would sit on the power scale (not that she'd need or use unless it's against a giant enemy), and because I doubt having robot dinosaurs just sit in seclusion for that long and not be discovered is doubtful.
