Me again.You really didn't answer my question, twilightprincess. I'll show you what I mean. Go on this site: chao.hippotank.com, then click on sonic adventure 2 battle, and find a link called "Dark Evo" or "Hero Evo" that is on the left side. Scroll down all the way then you will see dark/none/swim, dark/none/run, dark/run/fly, etc.(same thing for hero). Scroll up, while scrolling you should see dark/swim/none, dark/power/none, dark/fly/none, etc.(same for hero). So whats the difference? Do you have to recarnate the chao to get power/none, fly/none, etc.
