Alan's Goats

Alan hearing goats.

Alan is a very carefree man, keeping calm and quiet most of the time. However, he has a fixation over sounds, as he gets extremely annoyed by noisy sounds, and claims that can only be in peace when hearing the crying of a herd of goats in the plains.[2] If the sound comes from an enemy, however, Alan says that the sound is "dirty". He, however, doesn't hold back on his words, swearing almost all the time when enraged.[3] Due to this, he is a nonchalant man who does not care about his surroundings and immerses himself in the sound of his headphones.[4]

Alan enraged

He is also a very hot-headed person, always seen complaining a lot about his duties and wants to finish them quickest as possible.[4] When irritated, Alan immediately declares that he will kill the person, even though it's an unharmful threat.[5] Due to his impatience, Alan may want even to do things that weren't planned, although he claims it was because of curiosity.[1] These traits clash with Haiji's, leading the two to have a bad chemical.[6]

Alan's real personality

Alan's true personality.

On the other hand, Alan is secretly coward. He has an inner side that always complains and gets terrified when Alan has to fight or do something more difficult. Therefore, in complicated situations, Alan gets desperate and afraid about what would happen. Nevertheless, Alan endeavors to keep these feelings secret, keeping an indifferent expression and acting cool.[7] He himself admits that he is a man of the type that is "always calm and never taken aback no matter how bad the situation gets".[8] Alan sometimes overcomes this fear and gets determined to perform his duties, throwing threats at his opponents fiercely.[9]

Alan's Coat

Alan's appearance as a White Joker.

Alan is a young man with pale skin and a slightly long, messy, dark hair, that always cover his right eye, prompting Alan to often rise his hair to view better. He is also very tall and skinny, and has a pointed chin that sports a feint goatee. He's often seen with indifferent expressions, with semi-closed eyes and mouth and his hands inside his pants' pockets.

As a curator, he is seen wearing a full black suit with two lower buttons, a long-sleeved white polo shirt underneath it, and dark tie tied around the shirt's collar. Alan also wear black pants and dark shoes, as well a black belt normally unseen because of the suit.

When acting as a White Joker, however, Alan grabs a white lab coat with a triangle symbol on the lapel, related to the symbol featured in his Hammer. He's also always seen wearing light-colored headphones, that have a dark-colored star with a lightning crossing it in the ears, as well dark-colored cables that may connect to an unseen device under his suit. As a smoker, Alan can be seen smoking a cigarette sometimes.

Abilities Edit

Acoustic Resonance Edit

Once Alan taps the Hammer on his body, usually in his forearm, that body part becomes able to allow him to emit sound waves and manipulate their resonance.

  • Sonic Shockwave: Alan emits a sonic beam at a certain target, creating a strong blow upon impact with the target. The hit part of the opponent's body will keep reverberating that sound, regardless of how many more beams Alan emits.[10]
Sound Amplification: After the reverberating points are set in the opponent's body, and due to Alan's sharp skills which allow him to match the amplitude of the waves in a constructive interference aspect, such amplitude increases vastly. Then, with Alan acting as an input, he's able to amplify the output, increasing the sound wave's intensity to a point that induces a destruction phenomenon that blows up the body of the opponent.[11]
  • Frequency Control: Alan is able to change a sound wave's frequency to get a desired effect. He, however, relies on Mira Caldicott's body to channel the sound in order to change its frequency, what makes her act as an amplifier.[12]
Healing Frequency: Alan changes the frequency of the sound so the vibrations affect a body's molecules to activate them and accelerate the body's healing process.[13]

While using the Hammer's powers, the Alan's eyes gain a triangle, similar to the one seen in the Hammer's head, drawn around his iris. Also, when controlling the waves' resonance, Alan points at the target with his index and middle fingers, while keeping the thumb up and the others closed.

Enhanced Form Edit

After consuming a peculiar Hungry Joker Pill, Alan manages to artificially enhance his Eureka-compatibility and rises to the same power level as that of Heidi whom possesses a hybrid blood.

  • Continuous Acoustic Resonance: Alan is now able to continuously emit sound wave from his body. Thus, turning his own body into a mass of oscillating vibration.[14]
Vibration Armor: Taking advantage of his body that has been evolved into a mass of oscillating sound, Alan is able to control the sound emission and create a thin layer of coating at the surface of his body. This thin layer of coating is consists of vibrating sound that is able to disintegrate anything upon contact.[14]
  • Speed of Sound: Upon evolution, not only that Alan turns his body into that of a sound wave, he had also achieved the speed of sound. Through this speed, Alan can be seen easily manages to slip into Rosalie's line of defense.[14]

When in this form, Alan is now surrounded by several circular sound-like barriers and the Hammer had also receives a transparent coating where the said coating elongated and tapered at a single direction.[15] His irises marks had also been slightly altered in which his normal marks are now have additional lines protruding from each edges.[16]

Combinations Edit

  • Newtonian Apple: An experiment of Heidi consisted in combining his Eureka with Alan's, that proved to be successful. To perform it, Heidi and Alan touched their Eureka, that changed their colors.[17]
Crushing Wave: Once Heidi and Alan activate their powers, they're able to produce a devastating sonic wave that crushes everything in every directions, except in a small are that protects themselves and allies. They stand in the area as well, each one pointing to a side where the wave is being created, therefore creating an Omnidirectional Wave-Shaped Destruction. It was strong enough to destroy everything, from the floor to hard wreckage, inside a White Joker's base.[18]

Physical Prowess Edit

Crotch Punch

  • Enhanced Durability: Alan is shown to be quite durable and resistant person, despite his lack of fighting will. In one day, Alan managed to endure a punch and flying kick in his groin twice and withstand it only by shivering.[19] He also wasn't hurted when restrained by the hand of a giant monster in possession of Ragins. This ability, combined with Alan's Eureka, rapid reflexes, and smart movements make him a significantly good combatant.

Equipment Edit

Pythagorean Hammer Edit

As an Eureka-compatible human and White Joker member, Alan possesses one of the Eureka called the Pythagorean Hammer. This particular Eureka grants him the ability to emit sound waves from his body.[8]

It looks like an ordinary worn out hammer, with a large, rounded head with a triangle symbol in the middle, and two circular plates on its edges, that are the impact areas. The triangle symbol itself is further decorated with three circles, one on each corner. The hammer's handle is relatively small, but sized to be well-held.

Headphones Edit

Some improvements and developments were also made to enhance the use of Pythagorean Hammer, such as Alan's usage of headphones highly sensitive to sound vibrations, allowing him to locate disturbances from far distances[20] and to recognize a specific set of sounds.[21]

The headphones has the appearance of a normal headphones with a pair of loud speakers that cover his whole ears, connected by a thick headband crossing through above his head. Each speakers are also connected to a cable running through and connected to each other at one point. The speakers are decorated with an inverse star design surrounded by a circle. The stars itself are further decorated by a lightning bolt mark, extending in between the intersection of the upper star edges.

As they arrive at an isolated chamber and manage to tie both Heidi and Chitose, Alan proceeds on asking his colleagues to leave and questioning the scientist and his assistant. Heidi then reveals his intention while also mentioning that the hammer in the display is a fake. Hearing his testament, Alan snatch the Newtonian Apple from Heidi's pocket and brings out the real Pythagorean Hammer. He then starts threatening them while activating the Hammer's power.

Unfortunately, his threat is for naught as it only prompts Heidi to give him an even irrational demand in which increases the tension between Alan and Heidi yet again. After a slight conversation, Heidi finally complies and all four of them can be seen heading to one of White Joker base in which located beneath the British Royal Museum.[25] As they arrive, Alan quickly tries to detain Heidi who starts loitering and touching everything he sees.[26] Later on after Mira finishes explaining to them various information including the intel about the black organization, Mavro, Alan notices some noise coming from outside. Suddenly, the wall explodes and a man cloaked in black enters along with a huge monster along side him. As Mira confirms the man existence as a Mavro, Alan equiped his White Joker coat and prepares to fight in the Mavro's sudden invasion.[27]

Heidi quickly manages to save them with his Air Slicer, surprises even Alan himself as he wonders how Heidi could kept his cool in the face of a frightening opponent.[28] While Alan is still busy with his own mind, Ragins with the use of his electricity had managed to destroy the base's foundation and creates a cave-in. As Heidi is busy holding the debris with his Gravity Manipulation, Alan can be seen standing while hearing Ragins insulting everyone inside the base while calling them "maggots".
Alan against Ragins' puppet

Alan who is being dwarfed by the presence of Ragins' puppet quickly being shrouded by mixed feelings of fear and shock, although he still manage to hide it with his cool demeanor.[29]

Acting as if he is unfazed by the puppet, Alan unleashes his first Sonic Shockwave attack. Unfortunately, the attack is rendered useless as Ragins had already enhanced the defensive of the puppet with his electricity. Alan then can be seen launching multiple shockwaves towards the puppet while dodging every attacks himself. However after bearing no results with his attack, the puppet managed to grab a hold of Alan. Ragins who is confidence of his victory is then silenced when Alan reveals his true intention.

Heidi then questions him on the usefulness of the petite young girl to them. Alan then proceeds on explaining the history between Mira and the Pythagorean Hammer where in result, she is now able to act as an amplifier for Alan to activate his Healing Frequency.[32] After a slight confrontation, Alan manages to use his Healing Frequency with Mira's assistance and ready for another fight with Ragins.[13]

As the fight restarted, Alan and Heidi are once again being rendered unable to retaliate. Ragins is seen barraging them with direct at at extremely high speed in which prompt Alan to complain as his wounds are just healed a moment ago.
