Kamen Rider Cross (A.R. World)

The World of Kiva has its own version of Kamen Rider Ixa.

World of the Rider War
Though he was not seen in the Hikari Studio's original visit to the World of Kiva, Ixa appears in the World of the Rider War as Rising Ixa alongside Wataru (Kiva) and Kamen Rider Saga. Killed by Blade in the initial battle.

Restoration
As with all the Kamen Riders in the Rider War, Ixa was restored along with the World of Kiva after Decade was killed by Natsumi as Kamen Rider Kiva-la. He appeared in Burst Mode with Saga and reunited with Wataru back in the World of Kiva in front of Castle Doran.

Kamen Rider Ixa
Ixa appears as Rising Ixa in the World of the Rider War and Burst Mode in the World of Kiva after its restoration. However, is not seen in Save Mode, but it is assumed that it is his default prototype mode as with the original.

Burst
Burst Mode (バーストモード) is the first of Ixa's modes to appear. As the name suggests, Burst Mode creates a burst of heat that damages everything in range when transforming from Save Mode. It uses the Ixa Calibur to perform the Ixa Judgement (イクサ・ジャッジメント) and the Ixa Knuckle to perform the Broken Fang (ブロウクン・ファング). When performing the Ixa Judgment, a vision of the sun appears behind Ixa.

Rising
Kamen Rider Rising Ixa (仮面ライダーライジングイクサ) is the upgrade to Ixa System, known as Intercept X Attacker Ver.XI. As it is the perfected version, Ixa's power is at maximum strength. This mode is accessed through the new Ixariser and the Ixa Knuckle Ver.XI. After inputting the code, Ixa's outer armor is ejected and the head crest changes once again. In this form, Ixa can perform the Final Rising Blast (ファイナルライジングブラスト). The armor of this form has far more blue on the arms, legs, and head. The chest is primarily white with a red sun-like shape in the center, the core exposed due to the removal of most of the armor plating. The Ixa system would receive one final upgrade which allows for the user to access Rising Ixa from the initial transformation.
