Fossil Fighters: Champions expands on the features present in the original Fossil Fighters and, in many cases, introducing new options as well. The player can now choose to be either a boy or a girl at the start of the game and unlike the first you are given a choice of one of four starter vivosaurs (one for each element except Neutral and Legendary.
