Jack Thunder
Jackson Stormbringer Thunder (a.k.a. Jack Thunder)
Jackson Stormbringer Thunder, better known as Jack Thunder (ジャックのフンダール [Jakku no Fundaaru]) is the main protagonist of the Jack Thunder book series. He kicks off the series when he finds Stormbringer, a magical staff infused with the power of Air and the legendary Air Fragment, inside the mountain on his home of Tempest Island. He embarks on a quest to recover the six Anima Fragments, meeting friends along the way and setting out to banish the newly-returned Heart of Darkness which threatens Altairus.
Physical Description
General Physical Condition
Jack Thunder is physically healthy, but being on the cusp of puberty comes with its own set of problems. He is not exceptionally strong or nimble, being a spellcaster, but he can fit into narrow spaces and slip between the bars on some cell doors due to his small size.
Identifying Characteristics
When Jack Thunder carries Stormbringer, the staff is nearly twice the size that he is, making it visible from a distance.
Physical quirks
The position of his antennae reflect his mood. They tend to flop over or droop if he is upset or tired and stand on end when he is happy, determined, or startled. When he is particularly angry, they quite literally get "bent out of shape." They always bend at sharp angles, no matter what.
Special abilities
Jack Thunder's badge signifies his power over thunderstorms and lightning. When he generates lightning, it has a bright green color, the same color as the Air magic Stormbringer emits. The staff Stormbringer allows him to create massive weather events and summon weather spirits without the aid of other storm gremlins.
Apparel & Accessories
Jack Thunder wears a pine-green jumpsuit with rainforest green gloves, boots, and badge. His badge bears the image of a lime-green arrow-tipped lightning bolt.
Specialized Equipment
Jack Thunder wields Stormbringer, a trident-shaped staff forged in the element of Air.
Mental characteristics
Personal history
Before discovering Stormbringer, Jack Thunder's life was rather modest. He was raised by his older sister Frosti, and spent his days obsessively studying magical practice and venturing out to the lands Tempest Island passed over to explore. One day, when he was about 13 years old, he explored the foothills of Mt. Tempest hoping to find Air crystals for a spell and discovered a mysterious green glow coming from a cave he'd never seen before. Inside the cave he discovered a powerful trident-shaped staff. Though he experiences some bumps in the road, he quickly discovers the significance of the staff and embarks on a quest to find the other five Anima Fragments, meeting friends along the way.
Education
Jack Thunder's magical prowess is mostly self-taught. When he was younger, Frosti brought him to numerous dojos where he received basic magical training, but since he was old enough, he has taken charge of his own magical study.
Accomplishments & Achievements
Even before he found the Stormbringer, Jack Thunder was quite adept at weather magic. Almost all of his magic, save for some rudimentary spells he learned when he was a toddler, were self-taught.
Failures & Embarrassments
Unfortunately, Jack Thunder's self-imposed magical lessons did not always end in success. There were many times that he ended up accidentally summoning a storm or tornado that he didn't know how to control, and Frosti had to step in.
Mental Trauma
Intellectual Characteristics
Jack Thunder is incredibly gifted when it comes to memorizing and casting spells, but is very socially awkward. He tends to let his actions do the talking for him unless he gets particularly worked up.
Personality Characteristics
Motivation
Savvies & Ineptitudes
He is quite knowledgeable when it comes to Anima magic, having been obsessively studying it since he was old enough to take charge of his own education. He knows a lot about defenses against wendigoes and Null magic in particular. He is not the best at handling social situations, especially those that require special ettiquette. He is quite possibly autistic.
Likes & Dislikes
If there is one thing that Jack Thunder absolutely abhors, it is when people assume less of him or anyone else just because of age or social status. He will not hesitate to take on individuals of much higher standing than him if he feels like those individuals are being unfair.
He also tends to enjoy treats and activities that are associated with the lower classes in many Altairian societies despite funny looks. Even as a hero, he is still a child and is interested in many of the same things that children are.
Virtues & Personality perks
With few exceptions, he sees the best in people and wants the best for them. That being said, he is not opposed to turning to violence if he thinks it is what is needed to protect himself or those he cares about, though he generally draws the line at killing.
His emotional sensitivity, though he sees it as a flaw, also lends him the ability to see situations in a different light and see the humanity behind the monsters that the wendigoes make out of the Altairians that they attach to. This helps him immensely on his quest.
Vices & Personality flaws
Having little regard for status, Jack Thunder doesn't always have the best sense of when he should keep his mouth shut or what is and isn't appropriate to say to some people. He doesn't aim to be rude, but he says exactly what he thinks with little regard to how it comes across, and he doesn't give people respect just because they are in a position of authority. This gets him into many fights.
Also, because his tendency to cry easily clashes with his idea of what a hero should act like, he often tries to suppress his tears, to little success. Often, these efforts either end with him losing control of his magic due to stress or hardening his heart too much and unwittingly blinding himself to his own intuition. During his journey, he learns that his emotionality is actually an asset, not a liability, and learns how to make his emotions work for him rather than just repressing them.
Social
Contacts & Relations
Jack Thunder is quite socially awkward, but manages to build a base of trusted friends over the course of "Jack Thunder and the Fragments of Anima."
Family Ties
He lives with his older sister Frosti Thunder,
Social Aptitude
Despite what you might think, Jack Thunder is pretty introverted. For much of his childhood, he studied magic on his own and didn't have many close friends outside of Frosti and a few other storm gremlins. His tendency to blurt out whatever he is thinking can get him into trouble sometimes.
Hobbies & Pets
Speech
Jack Thunder has a high-pitched and somewhat raspy voice, akin to that of Rainbow Dash or Vanellope Von Schweetz. As he grows, his voice begins cracking, with there being periods where it sounds much deeper. As an adult, his voice is of a tenor register.
Jack Thunder's speech tends to be quite friendly and casual, even in situations where that normally wouldn't be appropriate.
