To be Continued here.

Accessories:

True Genius FullFullBottle

Silver Dragon FullBottle

Gold Rabbit FullBottle

(A/N: Silver Dragon FullBottle.)

(A/N: Gold Rabbit FullBottle.)

(A/N: True Genius FullFullBottle.)

He will wield a Silver Dragon FullBottle and a Gold Rabbit FullBottle and a Special FullFullBottle known as the Cross-ZBuild, aka True Genius FullFullBottle.

This FullFullBottle will have the powers of Cross-ZBuild, Build Genius, Build's 30 best Matches, Cross-Z's forms, Grease's forms and Rogue's forms including Prime Rogue form.

Form/s:

Take note that this form will only be achieved when the Hazard Trigger is present. When he wields this bottle's power and activates it with the Hazard Trigger, he will become pure white and silver and the user will become something more greater than Super Cross-ZBuild, Super Cross-ZEvol and Super RabbitEvol as Build True Cross-ZBuild Genius form will be his Ultimate final form.

(A/N: Kamen Rider Build - True Cross-ZBuild Genius.)

Due to his Ultimate form, his weapons he wields except for his Rider-based weapons will change its colours and articulations. Take Beat-Cross-Zer for example, it will turn Silver with Gold details in colour on it and it will become a saber called the Beat Cross-ZSaber once Cross-ZBuild Genius form is activated.

The Hazard form gimmick will still apply on his sides of his head and his shoulders but, they will be all white and silver.

The Genius Form Details and Gimmicks will apply on both the form's arms and legs. The FullBottles will only be embedded onto the arms, some parts of the chestplate and the back of the chestplate of the Rider form instead.

RabbitRabbit and TankTank Wing-like capes will be revealed at the back like the picture shown above.

He will wield Cross-Z Magma Knuckle on the right and Grease Blizzard Knuckle on the left as there will be a gimmick to it. The reason why he has two knuckles because these two knuckles will eventually fuse with his Twin Breaker Gauntlets, transforming them into Dragon Gauntlets, showing their specific Rider Symboles at each orb. 

(A/N: Dragon Gauntlets. Cross-Z Magma and Grease Blizzard. The other Gauntlet will be Grease Blizzard Knuckle-based colours.)

When his Dragon Gauntlets are activated, his right arm will have the powers of Cross-Z Magma and his left arm will have the powers of Grease Blizzard. 

His Lower Torso however will have Kamen Rider Rogue gimmicks with the combination of Build Genius fused onto it. This time, a pair of Ember Celicas will be placed onto his legs and they will be Spikey like RabbitTank Sparkling for a "Rogue" reason if you know his finisher.

This form will also have CrosMagma wings behind it as well, just like Super Cross-ZBuild but this time, its wing span is larger than Super Cross-ZBuild and it will be White and the rocky obsidion-like parts will be silver. Due to this majestic form, you will also have another pair of wings made of essence and all 60 FullBottles as they make an Infinity Sign which will become wings as they will be magically linked behind the user's Cross-Z Magma wings like Kamen Rider Mugen Ghost from Kamen Rider Ghost. Basically in this form, you will be a Silver-Armoured based Warrior.

Your Cross-ZBuild eye-visor will be different as the Dragon Eye-Visor will be Silver and the Rabbit Eye-Visor will be Gold, and they both will be in Cross-ZBuild based and Sparkling-based like the picture above.

In this form, the Build-Driver will transform into another Build-Driver which will be Silver in colour with Gold details on it to show that the user is in his ultimate form. This other Build-Driver will be called the Cross-ZBuild Genius-Driver, True Genius-Driver for short.

Now, talking about the Silver Dragon FullBottle and a Gold Rabbit FullBottle, the user can achieve RabbitDragon form with or without Hazard Trigger. When Hazard Trigger is equipped, the user will achieve RabbitDragon hazard form.

Include the cloak as it gives a good look on him. He will have several straps on him, equipped with all 60 FullBottles on them. He will look like Kamen Rider Eternal from Kamen Rider Double but, in a different scale.

(A/N: Kamen Rider Build - RabbitDragon HAZARD.)

Now that we have settled with his Weapons, forms and Accessories, let's look into what happens when we look at his Evol-side of him.

Hiro's Evol-side:

Looks:

This is what Evol Hiro will look like when he transforms or when he goes in a berserk when he sees his friends hurt.

(A/N: Evol Hiro's Looks.)

Accessories:

He wields the Evol-Driver to transform into powerful versions of EvolCobra, EvolDragon, EvolRabbit and Evol Blackhole and also being able to go EvolTank, EvolRabbit Black Hole, and EvolTank Black Hole and many more Evol forms. After that, he ends up becoming someone they have to snap back to reality.

Like Shadow, he will have EvolRabbit, Gorilla, Hawk, Ninjya, and other Evolforms. EvolMatches, RabbitTank, GorrillaMond, HawkGatling and many more EvolMatches. MadRogue Still applies as an EvolMatch, and Evol-Trigger same applies, even the FullFull Matches to form powerful versions of Evolforms, EvolMatches and EvolFullFullMatches to give Hiro the abilities and/or weapons of those forms.

(A/N: Evol-Driver.)

About the Nebulas Gauntlet:

The Nebulas Gauntlet wields the powers of the Space Stone. Some say they have seen its abilities, some say they have never seen its abilities before. When the Gauntlet snaps, its special ability is currently unknown.

(A/N: Nebula Gauntlet. There will be some icy-blue details on the Gauntlet with halves of Cross-Z Magma and Greaze Blizzard on it connected together to form  one whole symbol.)

Nebula Stones:

1. Portal Stone

2. Eye-of-Ender Stone

3. Space Stone

4. Nebulas Stone

5. Constillation Stone

6. Gravity Stone

Forms:

EvolRabbit

EvolGorrila

EvolHawk

Evol RabbitTank

Evol RabbitTank Sparkling

Evol Rabbit Blackhole

Evol RabbitTank Sparkling Blackhole

and many more

When Hiro uses the Evol-Driver, Evol-Trigger and Genius Bottle, he will transform into Evol Genius Blackhole Form, also known as Genius Corruption Form.

(A/N: Evol Genius Blackhole Form.)

And when he uses the Cross-ZBuild can and either the Evol-Trigger or the Hazard-Trigger, he will transform into Kamen Rider Evol Cross-ZBuild Form (Evol-Trigger) and Hazard Cross-ZBuild form/Cross-ZBuild Corrupt form (Hazard Trigger).

Data for form: -UNKNOWN-

(A/N: Evol Cross-ZBuild Form.)

(A/N: Hazard Cross-ZBuild Corrupt Form.)

All of these EvolForms, EvolMatches, EvolFullFullMatches and Ultimate forms which includes the Blackhole forms created and formed by the Evol-Trigger are active when Hiro is in his Evol Hiro state and when the Evol-Driver is present. When he knocks back to his senses, he will still be able to use these Evol forms, however, he will have another Hazard-Trigger due to his blood.

However this other Hazard-Trigger will soon be purified, transforming it into Greatness-Trigger, and when used on the Build-Driver and the Cross-ZBuild Genius FullFull Bottle, it will then form Kamen Rider Great True Cross-ZBuild Genius form (A/N: This form will show in Volume 6.).

(A/N: Greatness-Trigger.)

And to his other BestMatches, FullFullMatches, Genius and Super forms, they will become Greatness Bestmatches and Greatness FullFullMatches like example, Greatness RabbitTank Form, the Primary White Hero with the primary bestMatch.

Then so on so forth with other Matched forms.

Forms:

Greatness GorrilaMond

Greatness HawkGatling

Greatness NinninComic

and many more
