The Swooping Evil is a blue-and-green winged magical creature.[2] It looks like a cross between a reptile and an extremely large butterfly. When it is not flying with its spiked wings, the Swooping Evil shrinks into a green spiny cocoon.[3] It can be quite dangerous, as it can feed on people's brains, but also demonstrated being able to deflect at least some spells by flying into their path.
