Rider Statistics Ability Parameters Thouser's primary form is accessed by using the Amazing Caucasus Progrise Key and the Awaking Arsino Zetsumerise Key together in the Zaia ThousanDriver.
 * Rider Height: 204.2 cm
 * Rider Weight: 99.1 kg
 * Punching Power: 42.4 t
 * Kicking Power: 86.5 t
 * Maximum Jump Height: 58.1 m
 * Maximum Running Speed: 100 m per 1.8 seconds

Thouser's physical statistics are the highest out of any Rider at the time of his debut, with only his jump height being lower than Zero-One's Rising Hopper, Shining Hopper, and Shining Assault Hopper forms. Though he was caught off-guard at first, Thouser was able to quickly counteract Shining Hopper's Shining Arithmetic and overwhelm Zero-One with his superior physical strength. He is also able to easily overcome Vulcan Assault Wolf and Zero-One Shining Assault Hopper.

Kamen Rider Thouser is composed of the following parts:
 * Thousand Head (サウザンドヘッド) - The helmet.
 * Awaking Lancer (アウェイキングランサー) - The two silver horns. They are made of Snow Vigor (スノーヴィガー), a new type of metal alloy. They are extremely sharp, allowing them to be used as cutting and piercing weapons. A built-in phased array radar can search the area circumference without rotating the head. It reproduces the abilities of an Arsinoitherium to enhance the wearer's combat abilities.
 * Amazing Trident (アメイジングトライデント) - The three black horns. They are made out of the carbide steel ZIA-1000, and are used to throw enemies and control enemy braking. It has a built-in hearing device that collects sound from a three-dimensional area from the horns, enhancing hearing ability. It reproduces the abilities of a caucasus beetle to enhance the wearer's combat abilities.
 * Thousand Signal (サウザンドシグナル) - The base where the five horns meet. It learns enemy behaviour, makes tens and thousands of behavioural predictions and derives an optimal solution within 0.001 seconds which is then presented to the wearer.
 * Thousand Eye (サウザンドアイ) - The purple eyes. In addition to possessing a dynamic visual acuity that is ten times stronger than humans an a 200° omnidirectional viewing angle, it can switch between modes such as shading and night vision to ensure visibility in all situations. Additionally, it can display all kinds of information and has so many functions that it can be called clairvoyance.
 * Thousand Crusher (サウザンドクラッシャー) - The face armor. A number of horns with built-in radar and hearing devices are equipped to improve the combat power of the head. It is equipped with the Thousand Eye and protects the face with robust armor and extends the wearer's abilities.
 * Thousand Breast (サウザンドブレスト) - The chest. It is composite armor that combines the new metal alloy Snow Vigor, which has a Knoop hardness of 10,000, and ZIA-1000. It also has the characteristics of a high-performance sloped armor.
 * Thousand Shoulder (サウザンドショルダー) - The shoulders. It is a heavy armor made out of Snow Vigor, and is composed of complex surfaces, making it a slope armor with excellent bouncing performance (to repel away weapons). In addition, it is equipped with a function that follows the movement of the arm and actively follows the areas that require the most protection during that situation. It reproduces the abilities of an Arsinoitherium to enhance the wearer's combat abilities.
 * Infrast Tecter (インフラストテクター) - The bodysuit. By conducting thorough research on Kamen Rider Zero-One's Rise Architecter bodysuit, it was possible to greatly exceed its performance. In addition to a human enhancement system which utilises electromagnetic induction, it is possible to adjust the flow rate of each block of the liquid armor n-NA (「n-NA」) filled inside, and to perform power assist by functioning as a kind of artificial muscle. Additionally, durability has been greatly improved thanks to the application of Zaia Golden Coat (ザイアゴールデンコート), which can even block out cosmic rays. Additionally, its scalability as the basic equipment of Concept Thouser (コンセプトサウザー) is very high, and exerts it maximum strength by flexibly responding to resources such as the Progrise Key and the Zetsumerize Key.
 * Tect Arm (テクトアーム) - The arms. The Infras Tecter bodysuit, which exerts 1000x the power of humans, draws superhuman power from the wearer and can produce up to 10 times the arm strength of Kamen Rider Zero One Rising Hopper.
 * Tect Grab (テクトグラブ) - The hands. As part of the Infrast Tecter bodysuit, information on any touched object is sent to the Thousand Eyes, and various information can be obtained. In addition, during combat, n-NA filled within is pressurised and densified, thereby greatly increasing the destructive power of the punch.
 * Tect Leg (テクトレッグ) - The Infras Tecter bodysuit, which exerts 1000x the power of humans, draws superhuman power from the wearer and can produce up to 10 times the leg strength of Kamen Rider Zero One Rising Hopper. The thigh armor is equipped with a load-bearing device dubbed Amazing Loader (Ameijingu Rōdā), allowing Thouser to gain approximately 1000 times leg strength without faltering under weight. It protects the thighs and reproduces the abilities of a caucasus beetle to enhance the wearer's combat abilities.
 * Thousand Greave (サウザンドグリーブ) - The shin armor. It is equipped with Awaking Charger (アウェイキングチャージャー), a leg-strengthening device that demonstrates strong leg strength during kicks and dashes. It reproduces the abilities of an Arsinoitherium to enhance the wearer's combat abilities.
 * Thousand Boots (サウザンドブーツ) - The feet. It is made out of Snow Giver, which has a Knoop hardness of 10,000. The Snow Giver has been improved, giving it improved destructive and defense power.
