​Power and Abilities
Immense Demonic Powers - Due to being the son of One of the Great Satans and a High-level magus. He was born with a vast amount of demonic and magic powers, making it easy for him to do magic with wasting energy.

Immense Strength – Shirou is considered the one of the strongest character in the whole series. Even without the power of his armor, he’s capable of marking a number in several mid/high-class devils and angels at the same time without taking any major damage.

Immense Endurance - Shirou has shown to be just as durable even without his armor. In fact, his durability is in such level that he can withstand the power of Dragon-slayer spells. There's no explanation for this.

Immense Speed - Shirou can reach speeds faster than the eyes can see. Not only that, he’s able to move and attack in such speeds that he can leave several physical afterimages in her primary level. There's no explanation for this.

Adaptation - One of Shirou 's strongest abilities, he has the natural ability to adapt himself to become stronger and able to defeat anyone in a short period, being able to even acquired new abilities as his practice enhances his status in a few hours. The more he fights, the stronger his body becomes. However, he must keep fighting, or else his body lost the accumulated power back to his standard form.

Flight: Being a devil, he is capable of flight with devil wings or silver dragon-like wings.

​Equipment
The Demon Armor: Incursio is an Armor-type Teigu or a human made Sacred Gear created from the flesh of the Danger Beast Dragon, Tyrant and a prototype for what would later become Grand Chariot. The Danger Beast's power was so great that its flesh is still alive within, giving the Teigu the title of "Demon Dragon Armor".

Due to its origins as the Danger Beast Dragon Tyrant, Incursio possesses an aptitude for adaptation and evolution. Aside from its standard capabilities, it continues to evolve as the result of battles against several opponents, gaining new forms and abilities as time goes on. Due to being a full body-armor, Incursio has a near-indestructible defense with the only thing able to pierce it being other Teigu. The armor also greatly enhances the user's physical abilities such as speed, strength and agility. The users of Incursio are also able to wield a long spear or halberd-like weapon called "Neuntote", which can cut through anything with ease.

Adaptation and Evolution

Its ability to evolve is also shown on several occasions. Once Shirou inherited Incursio, the Teigu went through an evolution to adapt to his fighting style and to exceed its previous limitations. The armor that enveloped him was noticeably less bulky than it was previously to fit his agile form. Shirou can sense that the armor, after its evolution, has new abilities that he had yet to discover. One example is the ability for Incursio to manifest the head of the Tyrant from any point on the armor to deflect bladed weapons, protecting the user from an otherwise decapitating blow.

However, poses an imminent threat for those users who managed to draw out the second evolution. To be revived, the inner danger beast starts to overpower the user and transforms into its former dragon form with whatever traits the user decided to have. Is has been pointed out that Shirou has not reach towards the second evolution yet.

​Trump Card
The armor's trump card is the ability to turn the user invisible for a certain amount of time, depending on the skill of the user. As noted, a weakness of the invisibility is that while it masks the user visually from the naked eye, it does not hide their "presence", allowing skilled opponents to sense the user despite the invisibility.
