Harry's Species

An unnamed species of sapient humanoids. Only one individual has been encountered so far.

Biology
These aliens are between 7-8 ft tall (~ 2.1 - 2.4 meters). They are also bipedal and extremely strong, able to throw an adult Human through a wall.

Their skin is blue/purple in coloration and has the ability to shape-shift into different forms.

Alcohol has the same effect on them as it has on Humans, hinting at a similar body chemistry.
