Each pupa is approximately 6 feet long and at least a foot tall, which are insect-like and the similarity to its adult form are the tusks and its general face-shape. Because they are newborns, they are very weak, they can be easily killed by even a Level 1 Dispersion Pistol (though it is highly unlikely that you have a Level 1 Dispersion Pistol by the time you first meet them.), and it is very hard for a Pupa to kill you.
