The description for Innate states that powers such as Boost, Drain or Nullify cannot affect an innate trait such as an elephant's size or that of a ghost's incorporeal nature.
Permanent's description says that powers with this flaw cannot be turned off unless Nullify or another outside force affects a creature. Additionally this flaw prevents any improvements to the power using extra effort.
Looking at the stats for a Hawk on page 231, I see that it has Shrinking 8 with the Innate and Permanent states. I agree with this because the size of a hawk will always be tiny... because well, it's a hawk.
The Hawk also has Flight 2, however, this power is not innate nor permanent. Hawks have wings, it's a part of their genetic make up, and that is why I would argue that Flight 2 for the Hawk is innate. I would also argue that Flight 2 for the Hawk is permanent. A Hawk will always be able to fly unless of course an outside force, such as tying the wings together, physical damage or clipping the feathers, prevents it from flying.
That said, I would definitely appreciate if someone can help me understand why Shrinking for the Hawk is Innate and Permanent but Flight, and additionally its Super-Senses, are not.
Thanks for your time!
