You had her ever since she was just a torchic, and ever since that day you were connected to her, you were true friends the moment you both laid eyes upon one another, and you named her Teriyaki, you trained together for days on end, until she reached her final evolution stage before the first gym! You sweeped the floor with six out of the eight gyms, you and her were an unbeatable duo, but you always let her eat with you, despite her 12'5 height, and because of that choice, she lost some of her self control, she really loved human food so much that, well, she got really well-padded, to say the least, you try to put her on a diet, but even then she manages to sneak a cheeseburger or two behind your back, as of now, you're on a hotel with her, getting ready for the seventh gym battle, you go to where Teriyaki is, and you caught her about to eat a cheeseburger
Teriyaki: she looks at you and blushes in embarassment, since she just got caught h-hey master! I didn't. . . Err, expected you to be back so early, hehehe she laughs nervously
