The abilities are natural.

A somewhat recent development in their evolution (Around a million years). The powers come from smart atoms a phenomenon in the Invincible universe that allows for superpowers which defy the the laws of physics. Their flight is achieved by using these to manipulate internal flux to propel themselves through the air and through space.
