As Waganma gloats about the strength of the heroes, Nyan slips out of the pile of rubble Gearsper had buried it in. The monster grabs Futoshi and Waganma and drags them away. Suddenly, a high-speed object releases Nyan's grip on the two. The object circles back and appears at the hands of Drive Knight. Nyan inquires about the hero's identity. Drive Knight does not respond and leaps at Nyan, and the battle begins.
Drive Knight uses Tactical Transformation: Chariot and leaps at Nyan. The hero circles around the monster and sprays an anesthetic gas in an attempt to immobilize Nyan. He then charges Nyan with his bike, but the monster dodges through a crack in the ground. Drive Knight releases a strong solvent into the ground that forces Nyan back onto the surface. The hero launches several missiles at Nyan, which the monster easily dodges. Nyan goes for a direct attack, but Drive Knight uses Tactical Transformation: Knight and kicks the monster into the air.
Realizing his anesthetic gas had no effect on Nyan, he abandons his initial mission of capturing Nyan and decides to eliminate the monster. He uses Tactical Transformation: Flying Chariot to propel himself above Nyan then transforms into Bishop and punches Nyan into the ground. Nyan slips into Drive Knight's suit and slices it apart using Feline Retribution. Realizing he has no choice, he destroys his body to prevent Nyan from destroying his main body. Infuriated that he wasted the perfect opportunity to eliminate Drive Knight, Nyan extends his claws and unleashes more Feline Retributions which slice apart buildings, although Drive Knight is unharmed.
Declaring he will enter the hero's body and rip him from the inside out, Nyan unleashes flying slashes at him, but the hero is unharmed due to the strengthened armor provided by the transformation. The two engage in a brief scuffle, then Nyan slips into Drive Knight's body. Nyan slips around the body and attacks the hero from unpredictable angles with Feline Retribution, sadistically taunting the hero. As Nyan is about to release Feline Retribution yet again, Drive Knight raises his temperature to an extreme level and forces the monster out. He holds Nyan in a chokehold and uses Silver to stab the monster in the torso from behind. Drive Knight then incinerates Nyan, subjugating the monster and making the hero the victor.
Drive Knight announces the defeat of Nyan and walks toward Sekingar with the body of the monster in his hand.
