Spock!Robatalian shall be the greatest! And you may want to shorten the massive anime plotline section, as most people didn't know about most of the anime. Keep it down to just the basics of the plot, like "A man named Masquerade starting sending bakugan to the doom demention, and he soon gained a following. A small team of six tried to stop him", as the names and specifics would be unknown exept for the final battle. Other then that, I think you have a good RPG!
