Bro turns into a Lucario

Lucario, also known as the Aura Pokémon, is a bipedal, canine-like Pokémon with predominantly blue and black fur, being 5'4" feet tall. He possesses a short, round spike on the back of each forepaw, in addition to a third on its chest. He has red eyes, a long snout, and ears. When his mouth is open, two pairs of pointed teeth, one in the upper jaw and one in the lower, can be seen. He possesses cream-colored fur on his torso and blue fur on his thighs that resemble shorts. He has a medium-length tail of the same blue color as well. He stands on his toes rather than on its entire foot. He has developed four black appendages that hang down from his head, which rise when Lucario reads or manipulates aura, a special energy that he senses. He has a bit of a well toned body, slightly showcased through his cream-colored torso with pinkish nipples as well. His use of expletives is rare, only used during sex. Lucario's cock is 9 inches long, hidden within a sheath that protrudes when erect with slightly heavy balls. His sheath and balls are furry and blue, his cock being canine in nature with a knot. He also has a way larger than average ass that is bubbly and tight with a bit of a puffy hole as well. His sensitive spots, aside from his genitalia, are his belly and the appendages that hang from the back of his head.
