How do you change your outfit in fossil fighters?

Answer 1

Your outfit is determined by what dinosaur you choose as your favorite at the very start of the game (did you notice you don't see your character until AFTER you chose a dinosaur?). Tyrannosaurus gets red-and-black, Tarbosaurus gets you purple-and-black, Velociraptor gets you white/gray-and-black, Deinonychus gets you red-blue-and-yellow (the one you see in the opening), Triceratops gets you blue-and-black, Hypsilophodon gets you red-yellow-and-green, Lexovisaurus gets you yellow-white-and-light-blue, and Maiasaura gets you white-fuschia-and-light-pink.
After choosing a dinosaur, the only way to change your outfit is to start a new game.
