Gohan's armor is the wrong color in the "Goku Vs. Frieza" cut scene.
In the cut scene for the secret characters, Goku and Vegeta fuse into Gogeta using fusion earrings. Gogeta is the product of dance fusion, not the earrings. Further adding to the confusion in the English dubbed version of the game, the character is incorrectly called Vegito (the earring fusion of Goku and Vegeta).
One of the hidden characters is Super Saiyan 3 Goku. But on the character name by the life meter, it simply reads "Super Saiyan III" without a character name.
