Headscratchers / Sonic Rush

• If Blaze can fly why is she scared of heights and why does she need Cream to carry her?
  • Just because you have the power to fly something doesn't eliminate the anxiety or fear fostered from a fear of heights. Makes perfect sense to me. A pyrophobic isn't gonna stop being scared of fire just because they have pyrokinetic powers, for example.
  • Also, her power is more akin to hovering than flying. She can't use it to gain altitude.
• Why is Cream encouraging Blaze to beat up Sonic as if he were an actual villain?
• Why is it that Sonic's counterpart has a completely different superpower, personality, gender, and species, whereas Eggman's counterpart is just... a palette swap of himself?
