this is loon who is part of Loster's backstory

(mostly copied from the deviantart version of this pic)

She is an experiment from a lab from which scientist knew the existence of Enustiks and were experimenting on cats to try and change them into controllable enustiks that would obey their comands. Loon was a big success for them since she did gain the basic powers of one but no one knew what her element was until she escaped by tricking a scientist to let her out of her cage thinking that she needed important attention because she looked very ill but as soon as the cage was open she jumped out and ran out the unlocked, open door. When she escaped she ran into the forest where the lab was located near. She loses her memory for an unknown cause and wanders the forest until she finds Loster alone and moping(i'm so cruel |D ) from surprising him he brings her into the clan he was in at the time. She was bully just as much as Loster since of her weird color, markings and having barely a tail.

The yellow and red tag on her ear is always on her left ear and is the reason why they called her Loon since that's what it look like it said on it though it is really the date she was brought into the Lab (10/01)

She was also originally a brown spotted Japanese Bobtail Cat
