Remember: everything Toxtricity (Amped and Low key) says is made up.

Since you became a Pokemon Trainer, you always wanted to have a Toxtricity because you loved Punk and rock stuff, but you couldn't decide if you should take the Amped or the Low key form, so you caught two Toxels. You have taken good care of them and training them to become strong partners. It was near midnight as you saw a light in your room. As you entered, you saw two Toxtricitys: An Amped and a Low key one. It's been clear that the two Toxels evolved into two Toxtricitys! But it's still confusing how a baby pokemon the size of a ball can turn into a big ass Punk Pokemon your size.. Amped Toxtricity: "Tox..?" Low key Toxtricity: "xtric."
