Character name: Death The Kid
Fandom: Soul Eater
Timeline: Chapter 55.
Age: From looks alone, perhaps 13. However, Shinigami have really long lifespans, so it's hard to determine.
~*Magical*~ abilities and strengths:
Kid is a meister. He wields two Demon Twin .38 caliber Guns, Liz and Patty Thompson, because he is mentally unable to stand wielding just one weapon. He holds them upside-down and uses his pinkies to fire them. Liz and Patty are able to tap into his soul wavelength. Thus, instead of bullets, he fires pink beams of soul wavelength at his opponent.
Though it is normally difficult to match soul wavelengths with two different weapons, Kid is able to do so because of the mutual admiration he has with his weapons. Thus, they can perform a stable Soul Resonance with little difficulty. During Soul Resonance, both Liz and Patty turn into two cannons that are attached to Kid's arms -dubbed 'Execution Mode'- and their power considerably increases. So far, he has only used one move in Execution Mode: Death Cannon, a powerful cannon that fires a huge blast of energy at the opponent and leaves behind nothing but smoke.
Even without Liz and Patty, Kid is still a competent fighter. He practices Shinigami Martial arts. So far, without the help of BREW, he has only revealed one style: The Stance of Sin, a series of chops, kicks and blows. However, when the BREW is activated, another stance is unlocked: The Stance of Punishment. This stance allows him to tap into his Shinigami ability and use skull shields to block attacks.

Though he is a Shinigami, he is also a child, and thus cannot use many of the same abilities his father can. However, despite this, he still has an advantage over other human meisters. Kid has the Body of a Shinigami, and thus is a natural deterrant to poisons (even hair-dye) and weather conditions such as magnetic rays. He has an ability called 'Konso', which allows him to collect the souls not in his father's list within his body for safe-keeping. So far, these are all the shinigami abilities he can use in his normal state, however when the Demon weapon BREW is activated, many other Shinigami abilities are unlocked.

When BREW is activated, the three stripes on his hair -undeveloped 'Sanzu Lines'- start to fully connect. This unlocks power strong enough to evolve Liz and Patty from .38 caliber guns to .42 caliber. With connected Sanzu Lines, he is able to produce 'Shadow Skull Arms' from his body, that he used to reattach an arm. He is also able to use the 'Sanzu Falls Shot', a stream of energy that can destroy multiple targets at once.

Outside of fighting, Kid is also skilled at skateboarding. He owns a skateboard named 'Beelzebub' that is capable of flying and travelling at very high speeds. He has been shown to use one offensive attack with his skateboard: The Tornado Flip, where Kid flips his skateboard and launches at the opponent.
How would they use their abilities?:
Very sparingly. Though Kid has the powers and body of a Shinigami, he keeps a low key. He will only use his abilities when he is collecting souls, fighting some bad guy or punishing somebody for destroying the symmetry.
Appearance:
He has quite a small build, sometimes shown to be shorter than his two female weapons. He is usually dressed very sophisticatedly, his normal attire being a crisp and symmetrical, black-and-white suit. His skin is pale, and his hair is black -fitting nicely into his black-and-white theme. He sports many skull-related accessories, such as a skull-ring on both hands and a skull attached to his collar. The most notable thing about him, and unfortunately the only thing preventing him from being symmetrical, is his hair, that is black with three white stripes (Sanzu Lines) on the left. On occasion, he will wear a cloak and a mask that resembles his father's.
