The sun sets slowly, making the sky look like a colorful palette. The wind blows buzzing quietly and the trees rock gently and their leaves fly ridding the wind. A small pink petal fells on Rex's chest delicately. The boy smiles, his eyes open slowly and he gaze upon the sky. Everything is so peaceful, no EVOs any more, no more foes. Suddenly, a beam of light strikes next to him. The ground explodes into a cloud of dirt and dust, Rex is thrown away and his back smacks on a wall nearby. Instantly, his arms glow and they are covered by a metal surface. The huge Smack Hands shined under the sunlight. Rex's eyes scanned the area to find his enemy but he couldn't find it anywhere. Another beam of light shot toward the teenager but he quickly blocked it. The explosion caused Rex to fall some steps back.

There, behind the tall trees, a huge robot rise. Its gun was pointing to Rex's head. The boy ran forward, his Boogie Pack was created on his shoulders. He jump and lifted on the air with his super strong arms ready to punch his foe. A large metal arm flew next to him, Rex quickly dodged to the side but the robot successfully striked his Boogie Pack's left part, crushing it into a thousand pieces and scattered it on the ground. Rex bend to the right unbalanced and after a small spin he landed on the Robot's forearm. The huge red eye stared on him and the other arm came quickly to crush its enemy. Rex raised his arm and held the huge metal fist until his Smack Hand broke into half. He jumped on the side and ran as fast as he could on the strange enemy's shoulder. The enormous fist chased after him and grabbed Rex's leg. The teenager tried to escape but the Robot wouldn't let him. His eyes full of determination widen, his arms glowed with a blue light. Two sharp blades formed on the tip of his fists. The boy's Bad Axes cut brutally the metal surface that was holding him. The Robot quickly let Rex go and grabbed its cut hand with his other one.

Rex summoned his Slam Canon and shot his stronger shot against the huge red eye. As a large beam of light was fired from the eye and cut the metal ball in half, Rex jumped as high as he could. He stepped on a shard of the broken bullet and rushed to the eye with his Battle Saw spinning next to him. The blade striked the red pupil and broke through it. The boy fell inside a small room behind where the red pupil used ti be. He raised his head and screamed from what he saw. "Black Knight!".
