Dragon Form (ドラゴンフォーム, Doragon Fōmu) is a azure form form that allows Kuuga to be more agile and quicker, although his physical strength is lower than Mighty Form, Dragon Form enables Kuuga to and jump quickly in order to pursue the enemy. However, it also gives Kuuga less protection, yet being better suited for quick movements and more jump power. To make up for the lack of strength, he uses the Dragon Rod (ドラゴンロッド, Doragon Roddo) staff as his weapon, transmorgified by using any pole or stick-like object to manifest it. His finishing move in this form is Splash Dragon (スプラッシュドラゴン, Supurasshu Doragon), an aerial thrust attack to the torso.

Pegasus Form (ペガサスフォーム, Pegasasu Fōmu) is a green shooting form where Kuuga's senses are heightened to extreme, superhuman levels, enabling him to see, hit and hear his opponents with deadly precision. It also allows Kuuga to detect the enemy's position, despite whatever ability they may have to avoid detection. The downside to this is that it can not be sustained for too long because of the enormous strain placed on the nervous system from over stimulation (only 50 seconds), and if Kuuga exceeds this limit, he shall be knocked back into Growing Form and become unable to transform for two hours. Kuuga uses the Pegasus Bowgun (ペガサスボウガン, Pegasasu Bōgan) crossbow/gun hybrid weapon that can be created out of any gun-like object, commonly Ichijo's hand gun. His finishing move with the bow gun is "Blast Pegasus" (ブラストペガサス, Burasuto Pegasasu), an arrow shot from the bowgun after pulling the hammer back to the fullest length.

Titan Form (タイタンフォーム, Taitan Fōmu) is a purple herculean form where his defense is greatly increased, allowing him to withstand most of his opponents' attacks long enough to get in close range, despite sacrificing speed. This form has much larger armor that is mainly silver with large purple trims. Although this armor provides superior protection, it still leaves parts of his body exposed, thus making him still suspectible to damage. He uses the Titan Sword (タイタンソード, Taitan Sōdo) that can be created out of pole or stick-like objects, normally the control handle of his bike. His finishing move is "Calamity Titan" (カラミティタイタン, Karamiti Taitan), a powerful sword thrust wherein Kuuga twists the blade as it is impaled.
