Wally Buchanan

Wally Buchanan is an old friend of Erza's, having known her since childhood during their slavery days working on the Tower of Heaven. He is later revealed to be Hoteye's long lost brother.

Personality
In childhood he was a normal boy. As the slaves from the Tower of Heaven break free, he for first time sees an western cartoon. Now he considers himself a "Dandy" man and tries to make himself look dandy (=cool) every chance he gets. He also teaches others to be dandier (for example, he says to Milliana that talking cats are not unique, but they are cats because they are talking). Even his word bubbles are draw in a square style. His dandyness has a limit, as he tells Milliana later that Natsu is, in fact, not a cat.

History
Wally was one of a couple of kids that were taken from their home and forced to build the R-System or Tower of Heaven. It was there he met Erza, Millianna, Shou, Simon, and Jellal. The group attempted a few escape attempts but all usually failed. One day when the guards were threatening his friends due to Shou's crying, Erza rose up against them and inspired her friends and the other slave to do the same. It was this battle that he witnessed Erza come into her magic powers. Eventually the slaves were victorious and were set to leave the island. While looking through the supplies their captors had, he came across a movie crystal (crystals with movies recorded in them) of a western movie, which he found cool and presumably shaped his obsession with being "Dandy". After Jellal had become controlled by Zeref, he takes control of the tower and summons his friends to finish it after kicking Erza out. Branding her a traitor when she refuses to go along with Jellal's wishes and framing her by blowing up the ship the slave intended to use to escape to convince her friends and help finish the tower. Eight years later, the group completed the tower.

Tower of Heaven arc
Wally appears in a casino where Team Natsu is currently vacationing, introducing himself to Natsu when the latter complaining about losing a game then promptly ambushes him pinning him to the ground and sticking a gun in his mouth (This is toned down in the anime where Wally traps Natsu with his blocks, pins him to a machine Natsu was playing at and then tries to shot him). When Simon's use his lights out magic to throw the room in darkness, he shoots Natsu leaving him for dead then regroups with Millianna, Shou, and Simon to kidnap Erza (as well as Happy which he gives as a present to Millianna, an avid cat lover) and take her back to the Tower of Heaven. Unknown to him however, Natsu survived thanks to his Dragon slayer magic.

Later Natsu's group invade the tower to rescue their friend. Natsu finds Millianna's room and while fooling around with one of the costumed cat heads, Wally tries to ambush him only to be stopped by Millianna (as she loves cats and doesn't want to harm him since he looks like one). After Wally convinces her that Natsu the enemy, the two double team him and manage to gain the advantage. Just as he about to kill the dragon slayer, Happy intervenes and stops Wally. With Happy on the scene, Millianna hampers Wally's attacks allowing Natsu to knock out both in an instant.

Wally manages to recover and tries to continue the fight, but is interrupted by Gérard who announce what the Magic Council intends to do. Realizing Jellal's true intention, Wally is disheartened and confused till Natsu cheers him up before he proceeds for the top floor. Wally faints commenting on Natsu's scarf as he watches him go. He later recover and, at Simon's insistence, helps move Lucy and Juvia out of the tower then he along with Happy, Gray and Shou and the girls make their escape just before the Aetherion fires upon the tower and it. The group can do nothing more but watch from afar as the rest of the arc's event unfold.

Afterward he apologizes to Erza for his actions and morns the loss of Simon. Erza offers them an invitation to Fairy Tail which they consider but they stow away the night they suppose to leave, still ashamed of they did. Erza finds this out but doesn't stop them and allows them to go, but not before giving them a grand send off via fireworks as a way of showing them that they'll always be friends.

Fighting Festival arc
Millianna along with Shou and Wally watched Erza's dance on Fantasia Parade.

Magic and Abilities
Wally mostly wields a pistol that shoots out different magic bullets depending on if he want to kill or simply harm his targets. His main magical ability is teleportation in which in turns himself into a million blocks and moves from one place to the other. He can also use the squares to attack as well separate his body parts to attack independently.


 * Polygon Attack: Wally turns himself into millions of blocks and strikes the enemy from different directions.


 * 32 frames Per Second Attack: Wally once again turns himself into millions of blocks and strikes the enemy with 32 blocks at a time per second.


 * Prerendering Polygon Shot: This attack was never seen as Wally was hit by Happy before he could use it but this could be his strongest attack.

Trivia

 * Both Wally and his brother Hoteye seem to have polygon like bodies, though Wally's body seems a lot more block shaped in comparison.
 * In the extended version of Chapter 128, Wally is seen along side with Millianna and Shou watching the Fantasia festival.
 * Rather than a hand cannnon used in the anime, Wally uses a real Revolver in the manga.
 * In the manga he was smoking when he first appeared, in the anime he wasn't.
