I bought a haos Helios (580gs)and a ventus Alpha Percival (570gs) from Target the other day and the Helios has flat head screws for the feet but A pecival doesn't. So is my Helios fake?
It isn't fake. Some bakugan also have those bolts, especially for legs. You're not going to find fake bakugan at a major store like Target, Wal-Mart, etc.
