Well, I am deciding to use a character I've used before in a prior RP, though I'll have him take it easy on the violence and the swearing because of the rules here...
Name: His name is Joel.
Pokémon: He is a Jangmo-o.
Appearance: Joel is a small, quadruped Pokémon that bears resemblance to the ankylosaur, as he has some distinct features in his coloration. The lower half of his body is lightly white, while the upper half is in a darker shade of black. His baby blue eyes are big, as the large, heart-shaped scale on his head is darkly blue. His teardrop-shaped, loose-hanging scales that form a semi-ring around his shoulders and upper body are black and are dark blue on the outside edge. A small, solid dark blue scale is on the tip of his black tail, as his paws and feet each have three dark blue claws. (If this is too hard to visualize, simply think of it as his negative coloring when the colors are flipped around.)
Personality: Joel is a Pokémon that should not be taken lightly for his young appearance, as he has a very short temper and minuscule patience with others. He often gets into fights with others, as he always likes to have things his own way. He cannot seem to reason with others, as he typically uses force to solve problems. Although he may seem unruly to some, he can still be somewhat befriended at first if given proper time and care.
Other Info (Optional): He wears a sky blue scarf around his neck that has his name embroidered with love on the front.
