.It's modern day that when you turn 16 instead of getting your license and wanting a car; you get your own pet and want your own Avia Glove. An Avia Glove is a glove that allows you to mutate an animals DNA to become more powerful. How you do this is by touching the animal with the Avia Glove.
The glove is made by modern day technology and has a built in leveling system. The more matches you win the higher you level up. Once you've reached a high enough level you can upgrade your Avia Glove and bring your pet to a whole new level of power. Now when you touch your pet and mutate it to become more powerful you say " Reform" and It'll stay like that until you touch it again and say " Deform" because the glove is voice activated.
It's illegal to walk around with your pet reformed and can get your Avia Glove suspended. In this day you can train at your own house if allowed, in a gym, at trainer parks or enter a real match or competition. You level up by being in matches against other trainers or in competitions.
How you heal your pet is by buying a chip and inserting it into your glove and that tells the body what to do and how to do it.
The Avia Glove also allows you to interact with your pet by copying and decoding its DNA and using your own DNA and that allows speech to be plausible between the two.
Trainers can have up to three pets but can only have one pet no larger than a horse. [ Unless your not a trainer and a farmer etc.] All pets must travel with you, after all this isn't Pokemon
