Io

Io  is a moth scavenger in the post apocalyptic wastelands, who’s only true  friend is their armored (and armed) mutated mantis steed, Pinky. They  do not understand doors, so any time Io came across a building, they  would let the mantis pierce through the walls with the giant drill  attached to its arm to get in. Io is an unpredictable fellow, who might  turn on you as soon as you seem the slightest bit suspicious.
