Great Reiatsu: Eldridge has a great amount of Spiritual Power which is considered to be Captain Class. His Reiatsu is a formidable weapon, striking fear in those lower than himself. He can easily manifest his Reiatsu to some extent and have it affect the people around him mentally. He can maintain a high level of control over his Reiatsu, using it as he sees fit, but falling short of those who boast Vast or Immense Reiatsu.
Genius Intellect: Arguably, the most fearsome trait of Eldridge Kumori is his tremendous intellect. He is well-versed in the history and proceedings of the world and is privy to knowledge unknown to many, such as secret methods. He easily grabs the concepts of subjects completely new to him and masters them quickly. Even in the most complex and dangerous of situations Eldridge can rely on his calculating intellect to figure out the best course of action. His assessment of a situation is swift, ad-hoc and accurate, allowing him to deduce the nature of other people’s abilities and countering them, often only requiring a few instances of observation.
Master Tactician: He has shown himself to be a masterful and flexible tactician, capable of adjusting seamlessly to any given combat situation, if not planning out events well in advance. He understands the strengths, weaknesses and mannerisms of his enemies, and creates strategies to achieve victory; this includes preparing traps or leading his enemies along complex battle plans so he can even deal with enemies stronger than himself. Like this Eldridge can prepare victory many steps in advance and even incorporate his enemies and their plans into his grand scheme. Regardless of his own powers or those of others, Eldridge always remains a tactically cautious.
Great Strength: As a fighter with great physical conditioning, Eldridge has shown sufficient strength to partly block immensely powerful attacks and is capable of dealing with powerful strikes. His attacks also hold great potency behind them, easily enough to launch other people of the ground and through solid objects, as well as leaving deep craters behind.
Great Speed: Eldridge has demonstrated great speed and keen reflexes in battle. Even when caught by surprise from an enemy's attack, he can react in time to skillfully dodge or counter the assault. Offensively, he can keep up a quick and rapid assault which forces most opponents on the defense, as he leaves no openings in his attacks.
Great Endurance: Eldridge has incredible physical stamina, allowing him to endure the hardships of battle for a great length of time without slowing down. Only when utilizing constant high speed movement for an extended amount of time will he start showing signs of fatigue. Even with several wounds he can keep on fighting without significant physical hindrance.
Great Durability: Eldridge's body has received significant battle-conditioning and can take great amounts of punishment. He can take frequent unarmed attacks from weaker individuals on his body and come out unscathed, or with little consequence if not laugh about it instead.
Advanced Growth: As a fast learner Eldridge is able to grasp the basic control of advanced techniques in days where it would take other gifted Shinigami months. As such, he is able to reach the level of development required for Bankai at a much faster rate than the norm. With this being the case, he also tends to have a natural kind of affinity to be able to communicate with his Zanpakutō. Eldridge shows an uncanny level of adaption when fighting opponents he has fought before, provided that they are of the same level of power.
Hohou Expert: Eldridge excels in Shunpo. Though not particularly versed in its various techniques, he is proficient enough in the technique itself to keep up with and even surprise high-level Shinigami with his speed. He can even keep up with those of master level for an indeterminate amount of time. He is also very quick at close-range, being able to perceive and dodge swift sneak attacks and come out unscathed.
Zanjutsu Master: Eldridge is a master of swordsmanship, possessing flawless precision and performing lethal attacks with little effort. All of his strikes are powerful with equally impressive speed behind them. He can perform attacks with perfect precision and stop them in an instant. His skill in swordsmanship is great enough that he rarely requires even his Shikai in battle. His swordplay is at a level of skill that would be expected of a Captain.
Kidou Master: Eldridge has considerable knowledge of high level Kidō spells, casting several in quick succession, with no incantation and almost no effort, and still possessing formidable power. He possesses advanced knowledge of Kidō application and consistency, being able to cast all numbered spells, level 90's spell being more difficult to cast on a whim. He can use a low-level spell repeatedly in rapid succession and with devastating effects, as well as a counter to attacks. He can silently, and without warning, use low and mid-level Kidō to great effect. He can rapidly use a single high-level Kidō repeatedly, or multiple ones in quick succession, by name alone, without incantation or calling the type and level, while retaining considerable power and control.

- Utsusemi (空蝉, Cicada, referencing their molting): Allows for a movement at great speed leaving an after-image behind. The after-image may even appear to have taken damage. One can also exit a haori in one fluid move, leaving it behind in the air.
- Bunshin (分身, Alter Ego): A Shunpo technique where the user shunpoes from one place to another in rapid succession without halting. Multiple after-images might be created like this, all of them translucent and sharing the user's voice and Reiatsu pattern. Though these speed-clones cannot attack or suffer attacks like Utsusemi can, they do a better at hiding the user's true position and are far greater in number.

- Kirin (麒麟): Kirin is an extremely powerful, one-shot, lightning-based Kidou spell. After the activation of the spell, the user creates thunder clouds in the air by using his reiatsu to heat the air and produce the necessary storm conditions. Afterwards, the user draws natural lightning directly from thunder clouds to supplement the power of his strike and controls it with his reiatsu. Unlike most techniques, which are based on the user's own spiritual pressure, this one uses the natural lightning, which — as noted by Eldridge — reaches the ground in an untraceable speed. Once the lightning source has been acquired, shaping and guiding the lightning to the target requires very little reiatsu. Kirin is generally shaped with Chinese dragon-like features. Most notably its head with eyes having thick eyelashes, a mane that always flows upward defying gravity, a beard, and scales on the body ranging either somewhat scaled to totally scaled like a dragon. However it can also maintain its simple lightning form. In addition, usage seems to disperse the thunder clouds as the sky clears up of clouds after use. The technique is strong enough to completely obliterate a small mountain.

The technique is strong enough to completely obliterate a small mountain.
- Chidori (千鳥, One Thousand Birds): The Chidori is a much smaller version of Kirin that concentrates the lightning around the user’s hand. To perform, the user first gathers lightning to their hand by heating up the air around it and generating natural lightning; the high concentration of electricity produces a sound reminiscent of many birds chirping, hence the name. Once the lightning is gathered, the user charges at his target and thrusts the Chidori into them, piercing them at the intended area of the attack. Despite the sound it makes, the rapid speed at which it’s used makes it useful for assassinations or quick attacks.
- Hiraishin (飛雷神, Flying Thunder God): Hiraishin is a Kidou spell, which allows the users to transport themselves to a given marked location instantaneously. To activate this spell, the user places a special seal or "technique formula" to mark an intended destination. After this is done, they can at will enter a dimensional void that instantaneously transports them to anywhere near to the location of the seal (within a one meter diameter). The mark can be applied to almost any area through brief physical contact, including an opponent or other surrounding feature. Because this spell is able to affect anything that is in contact with the user or somehow connected to their spiritual pressure, they can also use this spell to teleport other objects or people, though the size of the object dictates the amount of reiatsu required. As Eldridge also noted, the marking formula never disappears from a marked target unless he wants it to disappear. Hiraishin is a unique spell, because unlike any of its other counterparts, its spiritual pressure usage is directly proportional to the size of what's being teleported and indirectly proportional to the user's familiarity with the shape of the target, not to how far it's teleported. Unlike Shunpo, Hiraishin is faster and untraceable because of the fact that there is no movement involved, but instead teleportation.
- Hiraishin: Goshun Mawashi (飛雷神・互瞬回し, Flying Thunder God: Mutually Instantaneous Revolving): If a person is marked with the spell or given the reiatsu of the user of the technique, this grants them the ability to switch their positions at any point in time during a battle.
- Hiraishin: Ni no Dan (飛雷神・ニの段, Flying Thunder God: Second Step):The user throws his weapon with Flying Thunder God mark at his opponent. Then he teleports to it, attacking his enemy from his back or blindside.
- Hiraishin: Rasen Senkou Chou Rinbukou Sanshiki (飛雷神・螺旋閃光超輪舞吼・参式 , Flying Thunder God: Spiralling Flash Super Round Dance Howl Style Three): This technique employs the use of Flying Thunder God spell with Eldridge's Air Manipulation. Eldridge throws several Flying Thunder God Kunai around the enemy, and teleports to them simultaneously. After teleporting to each Kunai, Eldridge uses Air Manipulation to repel the enemies with great force and hit them from different angles. It is a technique that was initially developed to create an opening for an attack. However, with the usage of the Air Manipulation it was shown to be enough to defeat an entire platoon of Shinigami.
- Hiraishin: Jikuu Shippuu Senkou Ren no Dan: Zero Shiki (飛雷神・時空疾風閃光連の段・零式, Flying Thunder God: Space–Time Hurricane Flash Sequential Steps: Style Zero): Eldridge sends all six of his Flying Thunder God kunai at his opponent, and then teleports to each of the kunai as they fly near his opponent. After slashing his target several times with his sword, Eldridge ends the combo with an energy blast, that either being a Hadou spell or his own technique, Kazekiri.
- Hiraishin: Dourai (飛雷神・導雷, Flying Thunder God: Guiding Thunder): The Guiding Thunder is a space-time barrier spell, based on it's parent spell; Hiraishin. The user creates a transparent barrier of various sizes. This barrier spell incorporates the use of the Flying Thunder God formula to erect a barrier space capable of warping away anything which comes in contact with it. Once erected, the barrier has proven powerful enough to warp away destructive techniques. Once warped, the subject of the spell can be directed to another location marked by the formula.
- Hiraishin: Goshun Mawashi (飛雷神・互瞬回し, Flying Thunder God: Mutually Instantaneous Revolving): If a person is marked with the spell or given the reiatsu of the user of the technique, this grants them the ability to switch their positions at any point in time during a battle.
