Ryoto Kaminaro

* 2022-2023 (As Build)
 **Kamen Rider Build**
* Cross-Z

**Kengo Caesar** (ケンゴシーザー, *Shīzā Kengo*, César Kengo) was a 15-year-old (17/18 as of the new Build plotline) member of Faust and creator of the Build Driver with his older sister, Reina. Although, after a lab accident, Reina later gave him a new face and wiped his memory as he took on the identity of **Ryoto Kaminaro** (カミナロリョウト, *Kaminaro Ryouto*). After stealing a copy of the Build Driver from Faust, he used it to transform into the first **Kamen Rider Cross-Z**. But, after damaging it in a battle, he had to go and steal another copy, using it to become **Kamen Rider Build**.

## History

### Early Life

Kengo Caesar was born in Rio de Janeiro, Brazil with his older sister named Reina. As children, the two were especially close. They did everything together, they studied together, played together, cooked together, etc. The two of them were the smartest children in their class, getting into top tier classes. As a family, they later moved to Japan for bigger opportunities. When Kengo was 14 and Reina was 16, the two of them successfully joined a company named Faust. It was their part-time job, as they went to school at the time. They created Faust’s most powerful weapons and drivers together, as a duo. But, something went wrong when they made a special driver. They were messing with different chemicals, one of them blowing up in Kengo’s face. The impact immediately knocked Kengo out, and it also burned his face completely.

Reina was scared, afraid that this might have been her fault. She took Kengo’s body to her side of the lab, making an entire new face for her unconscious little brother. She then managed to wipe his memory, giving him to a new family.

### Cross-Z Days

He managed to steal from Faust, stealing a copy of the Build Driver. He also stole some Fullbottles and a Dragon Type thing before running away and returning home. He eventually got roped into another branch of Faust, meeting one of it's members; Payne Percival. The two built a rocky friendship, Ryoto lying to Percival. He told Percival that his name was Kengo instead of Ryoto; a name that he had dug up in old files of his.

He worked with that faction of Faust for a while, before eventually quitting after listening to another friend he made. Percival and Ryoto then met at a gas station again, making sure that Percival had no hard feelings about Ryoto's betrayal. They were eventually on each other's good side again, but it all went wrong when he was involved in a battle.

To defend his friend from an attack, he launched himself infront of a finisher, causing his head to get sliced open. The finisher also broke his driver, leaving him driverless and in the hospital for a couple weeks. He also had memory loss, causing him to behave like a child.

### Becoming Kamen Rider Build

After being released from the hospital, Ryoto had decided to sneak back into Faust. While he successfully sneaked in, he snatched driver and fullbottle designs, going back home. While there, he made a copy of his own driver and he put the essence of a rabbit in a fullbottle. He named his new suit "Kamen Rider Build".

## Personality

"*I suggest a fair fight.*"

―Ryoto before a battle.

Ryo is a sweetheart to the people he knows best, (such as Sapphire and the Gaim Riders) trying his best to protect them. He can be extremely violent to enemies, releasing all of his anger onto them. Although he seems dumb, he’s very smart behind the scenes, creating the Build Driver before his memory was erased. He can also be seen as scary in some situations, due to how tall he is. He stands at 6'5 at only 18, making him one of the tallest people in the server as a whole.

Ryoto transformed into **Kamen Rider Cross-Z** (仮面ライダークローズ, *Kamen Raidā Kurōzu*) utilizing the Cross-Z Dragon, which adapts the Build Driver's two slots into one, allowing him to use only the Dragon Fullbottle to transform.

Utilizing Cross-Z, Ryoto became a force to be reckoned with, blowing far past Build, Night Rogue, and Blood Stalk's Ability Parameters. It possesses a greater punching power than Build's GorillaMond Form, has a stronger kicking power than Build's KeyDragon Form, and exceeds RabbitTank Form's maximum jump height. Though it loses to some of Build's more agile forms, it is still faster than both Night Rogue and Blood Stalk.

Cross-Z has unique features that help differentiate it from Build's normal Halfbody-based forms, most notably the addition of the **Drago Live Razor** (ドラゴライブレイザー, *Dorago Raibu Reizā*) body-shoulder armor pieces at the front.

Cross-Z's personal weapon is the Beat Closer. After acquiring the Cross-Z Magma Knuckle, he occasionally uses it in this form as well. Ryoto lost his ability to transform into Cross-Z after his driver was broken.

**Appearances:** *Build* Old Episodes

Kamen Rider Build can assume a variety of different forms, called **Trial Forms** (トライアルフォーム, *Toraiaru Fōmu*), using different combinations of Fullbottles. However, each one has a **Best Match** (ベストマッチ, *Besuto Matchi*) with another Fullbottle that creates an especially powerful form. Best Matches usually have unique names in comparison to other mismatched forms, and the caps of Fullbottles indicate what Fullbottle is its Best Match.

Build initiates a finishing attack by turning the Build Driver's Vortex Crank again. The finisher of all Trial Forms is called the **Vortex Attack** (ボルテックアタック, *Borutekku Atakku*), while the finisher of the Best Matches is called the **Vortex Finish** (ボルテックフィニッシュ, *Borutekku Finisshu*).

**RabbitTank Form**

"*Rabbit! Tank! Best Match! Are you ready? (Techno rock music) Hagane no moonsault! RabbitTank! Yeah!*"

―RabbitTank's transformation announcement

Rider Statistics
* **Rider Height**: 196 cm.
* **Rider Weight**: 99 kg.

Ability Parameters
* **Punching Power**: 9.9 t. (right arm)/17 t. (left arm)
* **Kicking Power**: 23.7 t. (right leg)/17.8 t. (left leg)
* **Maximum Jump Height**: 55 m.

**RabbitTank Form** (ラビットタンクフォーム, *Rabitto Tanku Fōmu*) is Build's red and blue primary and default Best Match form form accessed from the Rabbit and Tank Fullbottles, hence known as the **Moonsault of Steel** (鋼のムーンサルト, *Hagane no Mūnsaruto*). It is a Touto Best Match, and is themed after a rabbit and a tank.

Being Build's most balanced (and second fastest) form, RabbitTank is the Best Match form favored by Ryoto, despite being able to transform with any Fullbottles. The Rabbit and Tank Fullbottles are noted as having a particularly high synergy with each other and compatibility with various mechanisms, thus RabbitTank is the basis of several upgraded forms Build can access.

In this Best Match form, Build is armed with the **Tank Roller Shoes** (タンクローラーシューズ, *Tanku Rōrā Shūzu*) on his right leg for kicking attacks, and can also act as a working tread to roll along on a flat surface.

This form's weapon is the Drill Crusher.

As a Best Match, this form has two finishers:

* Build Driver finisher:
	+ **Vortex Finish** (ボルテックフィニッシュ, *Borutekku Finisshu*): Build dives underground to send a white energy chart flying up to the surface with the dotted line securing the enemy before leaping back up, and delivering a kick whilst riding the chart's line. According to Blood Stalk, this finisher has a Hazard Level of 3.2, and then 3.7 when Build attacks him out of anger.
* Drill Crusher finisher:
	+ **Vortex Break** (ボルテックブレイク, *Borutekku Bureiku*):
		- **Blade Mode:** Build channels the energy of a Fullbottle in his Drill Crusher and performs a powerful slash.
			* Biotic:
				+ **Rabbit:** The Drill Spiral Blade spins such that it creates an energy whirlpool before Build performs a red energy slash.
				+ **Gorilla:** The Drill Spiral Blade cloaks itself in an energy projection that bears a striking resemblance to the Muscle Glove.
				+ **Ninjya:** Purple energy Drill Spiral Blades are projected and spin violently around the Drill Crusher.
			* Abiotic:
				+ **Rocket:** The Drill Crusher charges at the enemy and attacks like a rocket.
		- **Gun Mode:** Build channels the energy of a Fullbottle in his Drill Crusher and performs a powerful blast.
			* **Harinezumi:** Build shoots white energy spikes at the enemy.
* Fullbottle Buster finisher:
	+ **Just Match Break** (ジャストマッチブレイク, *Jasuto Matchi Bureiku*): Build channels the power of two Fullbottles for a powerful attack.
		- **Buster Blade Mode**
			* **Gold Rabbit + Silver Dragon**: Build jumps into the air and performs a powerful downward slash covered in gold and silver energy, followed by two horizontal slashes.
