The puppet of Wall, in its human form, resembles a tall, oddly shaped man with unnaturally long arms. It has a rather big, oval-shaped face, small pointy ears and glaring eyes with dark bags underneath them. It is often seen with a mischievous grin and seemingly has no nose. Its hairstyle resembles an antenna; strands of its hair juts upwards, forming one thin mohawk at the top of the head, while the surrounding parts of hair are somewhat cut apart from one other, shaping a distinctive pattern on both of its temples. In regards to clothing, the puppet wears an ensemble consisting of a dark, high-collared open jacket with the sleeves slightly rolled up, over a long, striped sweater and light colored, tight-fitting jeans. The jacket bears an insignia on both sides of the upper chest-region, together resembling the wings of a bird. Around its neck, the puppet adorns a necklace consisting of various unspecified accessories, placed in a particular order. In addition, it also sports a camouflage patterned scarf, as well as round, leopard-print shoes.
The puppet is usually shown with a mischievous grin, regardless of the situation he's in, lending credence to his objective and controlled persona. Wall also seems to be conscious of villainous and unjust actions, with him mentioning the sinful act of capturing his majesty's former lover, but nevertheless obliges dutifully. It also expresses the tendency to speak with reference to law and order, dictating at one point that Weakness allows it to conduct prosecution, and said that it was going to "impose the death penalty" upon Freed.
The real Wall (in his "impulsive" personality), however, is a maniacal individual who wears a crazed grin and violently cackles at things he finds humorous, including his own comrades' defeat and capture. However, even when he finds things humorless, he still laughs, such as at the prospect of Fairy Tail sullying the name of the Alvarez Empire all by themselves. Wall has also exhibited a degree of arrogance, referring to himself as "the great Wall" and the "Machias tribe elite". What makes Wall remarkable is his ability to, as a Machias, completely rewrite his own personality to better suit his current predicament; in order to ensure his own victory, as the smallest chance existed that his current personality would cause him to lose in a fight against Laxus Dreyar, Wall discarded his carefree persona and adopted one that was "heartless". Said change removed any ounce of frivolity in his character, and reduced him to an emotionless killing machine.
Weakness (弱点特攻兵ウィークネス Wīkunesu): A Magic initially utilized by his puppet to create mechanical soldiers that exploit his enemies' weaknesses, Weakness is a Magic that utilizes the basic processes of Alchemy to form its constructs. The real Wall demonstrated the ability to additionally construct extremely complicated, powerful machinery with little to no effort, such as a Jupiter-like cannon, and even less complicated weapons, which include heat-seeking missiles copper and zinc-infused 9mm bullets, electric-imbued mechanical latches, etc. One of the fundamental abilities of Weakness is to also allow him to examine, with his eyes, the body of the foe in question, which allows him to assess their overall statistics and abilities, as well as even view their internal organs. Alternatively, Wall can also use his Weakness as a visual aid for attacking with his created products by locking on to targets that are within an adequate firing distance.
