Skull gets my Vote

Skull ahead with 14! Super-1 in second with 12! Amazon in last with 2! Battle closes soon! Put input in now!

Caucasus and Agito have a brutal battle to the end, while DiEnd uses Invisible and leaves :lol.

Then after they kill each other he goes back and steals their stuff. He is a unrepentant thief after all:lol

That's more or less what I'm thinking, yeah.

So we're agreed, DiEnd is only good for one thing making him a complete...wait, is that word allowed here? :p

Our competitors' stats!
Agito-

• The Alter Ring is a mysterious belt bestowed upon Shōichi by the Over Lord of Light. It holds the "Seed of Agito" and is the source of his power. As he grows in strength, he would unlock its full powers.
• Basic form is Ground Form, with 5 other forms
• Ground Form is the first of Agito's numerous forms. This form harnesses the power of the earth, turning Tsugami's entire body into a lethal weapon, with bone-crushing blows and crippling locks. Of all the forms, the golden Ground Form is the most balanced, with power, speed and strength working in harmony to make the most of its capabilities.
  At its peak, the crest horns upon his head opens, pushing all of Agito's capabilities to their fullest, emanating beneath his feet, into his legs to execute his Rider Kick, a jump kick of incredible raw power and force; with a force of 30-tons, or with the Machine Tornador, the Rider Brake jumping off the Machine Tornador at full speed, and Dragon Breath, which involves ramming the side of the Machine Tornador into the enemy. Ground Form has also been shown to be able to use a Rider Punch.
• Storm Form is the second form of Agito, triggered when Shōichi activated the left switch on the Alter Ring, 'opening' the "Blue Dragon's Eye." The blue "Storm Form" harnesses the power of wind through the left arm, and imparts the form with supernatural agility and reflexes. The most nimble of forms, Storm Agito maneuvers with such swiftness and cunning that its movements parallel foresight.
  This form also carries a signature Storm Halberd- a folding, twin-bladed pole arm that serves as Agito‘s primary means of attack while in Storm Form. But, however superior in overall speed and agility, the Storm Form is by far the weakest in comparison to the other forms, in terms of power and strength. His final attack is Halberd Spin, whipping up a powerful gale by twirling the open Storm Halberd at rapid speeds, blowing away everything in the general vicinity, and gaining swing-momentum for a finishing strike, and with the Machine Tornador, the Halberd Brake.
• Flame Form is the third of Agito's forms to be revealed, triggered by activating the right switch on the Alter Ring, 'opening' the "Red Dragon's Eye." The searing power of flame flows through the right arm and blesses the red body of the Flame Form with incredible strength. Aside from its apparent superiority in the areas of power and defense, the Flame Form possesses phenomenal heightened senses; his senses have increased to point where an enemy's presence - whether distant, hidden, and/or invisible to the naked eye - can be detected with frightening precision.
  This form also has exclusive access to the Flame Saber, using it in his Saber Slash attack which anything he slices with the blade is reduced to ashes, or the stronger Double Saber Slash with an additional Flame Saber to deliver a double saber-stroke attack. With the Machine Tornador, Flame Form is able to use Saber Brake.
• In the brief instance when he was able to recover his memory, Shōichi revealed the power to invoke a new level of transformation possessing extraordinary properties of Ground, Storm, and Flame forms: the Trinity Form. This form's capabilities, a combination of all three, harness the strongest qualities of Agito's powers and execute the forms' finishing attacks. In this form, Agito can wield both Storm Form's Storm Halberd and Flame Form's Flame Saber.
• Burning Form, known as "the power awakening to infinite possibilities," is born when Shōichi learned to channel his fighting spirit into power. The transition was rough on Shōichi's body, as he was virtually incapacitated during the emergence of this new power. But as they manifest, the nature of the power became clear; and it is one not easily controlled. The Burning Form amplifies and translates Agito's fury into power; thus the greater his rage, the more powerful the Burning Form became, as seen in his Burning Rider Punch attack. His signature weapon, the Shining Caliber, is a dual-bladed weapon capable of two modes: Single Mode, as a dual-blade sword and Twin Mode, as paired blades. Burning Form uses the "Single Mode" exclusively for his "Burning Bomber," cutting down the enemy with lethal blazing strokes.
• Most Powerful Form- Shining Form
• Shining Form, also known as the "evolution of infinite possibilities," was awakened by the light of the sun. It was an evolution unlike anything ever anticipated by the Overlord, born when Shōichi molts after having mastered his power in Burning Form. Although the power of his fists remain unchanged, all other attributes being pushed to their peak, making Shining Form Agito's greatest form. In Shining Form, Agito wields the Shining Caliber in Twin Mode as paired blades for his high-speed "Shining Clash" attack. His final attack is Shining Rider Kick, concentrating the Agito Power before him to accelerate to supersonic speeds as he attacks with his strongest flying kick, piercing his enemy with extreme force. In Movie War 2010, it was shown that Agito Shining can also perform the Shining Rider Punch.
• Weaknesses- Unfortunately, when Shōichi once again loses his memory, the power of the Trinity Form was sealed away. Out of all of Agito's forms, Burning Form is the slowest of them all.

Caucasus:

• Caucasus Zecter can attack for him
• Can utilize Clock Up, allowing him to move faster than the eyes can see
• Can utilize the Hyper Zecter, and freely control time
• Carries around a blue rose...yeah, not sure how that's a power but oh well.
• Weakness- Can be incapacitated if Zecter is rendered immobile, preventing him from transforming.

DiEnd

• Wields the DiEnd Driver, allowing him to shoot and henshin
• Can summon other riders via Kamen Ride Cards, and use FFR Cards to turn them into powerful weapons
• Can travel through dimensions
• Invisible Card- Allows him to get out of sight
• Illusion Card- Allows him to make copies of himself
• Blast Card- Allows DiEnd to unleash a barrage of blasts
• Most Powerful form: Complete Form
• With the Gekijouban card, he is able to summon the 8 Riders (G4, Ryuga, Orga, Glaive, Kabuki, Causcaus, Arc, Skull) and have them do their final attacks.
• Weakness: Loves treasures, will often go after them regardless of consequences. Taking his DiEnd Driver can result in another person becoming DiEnd and leave him powerless.

FINAL BATTLE RIDE! This battle closes Monday!

Screw you guys I'm voting Diend :p

Not gonna lie, its mostly because he's my favourite Rider and I know very little about the other two, but I have got some reasons for my choice.

(This is assuming that its a scenario where Diend actually wants to fight).

* The guy practically has an army at his disposal. He can summon riders, final form ride and have summoned riders used transformed riders. 'Nuf said.
* His weapon is excellent for range attacks, and for close combat he's pretty quick on his feet. Sure it's not clock-up fast, but it's not exactly slow.
* He's sometimes able to exploit his opponents - for example, he set AU Black up against Femme because Black wouldn't fare well against female opponent.

Those are my reasons, and since I don't expect Diend to win anyway I'm sticking to them :D

caucases can clock up and kill diend before he even pulls out a card, same for agitos death, case settled
