• Rider Punch and Rider Kick
  Rider Kick

  : The primary killer moves in the entire series were the and which is charged with King Stone Energy at the right fist and the right foot. After delivering either one or both moves to any monsters, they would be engulfed in flames before finally destroyed. Kamen Rider Black discovered his weakness when he was fighting a Crab monster. His Rider Punch had no effect on the monster due to its strong shell. To increase his capabilities, Kamen Rider Black trained himself to find a new killer move to destroy the monster. While training, he discovered a new Rider Punch which was more effective and more deadly. These stronger variations of Rider Punch & Rider Kick gave out stronger force of light and were more blinding. The difference between the new and the old moves were that the new ones required Kamen Rider Black to touch his knees before hitting his enemies.
• Rider Chop: Though not used by Black for finishing off monsters, this move can slice through most materials, and the series mentions that it can cut through 100mm of solid steel.
• Multi-Eye: His eyes would glow and the functions were to see monsters' movements in the dark and to detect their weaknesses.
• Sensoring Ears: The triangular structures on both sides of his head would glow purple and the function was to hear voices and sounds from far away.
• Rider Sensor: Kamen Rider Black's antennas would move to detect monsters which were moving too fast to be seen.
• Power Stripes: His Yellow-Red-Yellow bands on his neck and wrists would glow to repel any monsters' sticky fluids or goo on his body.
• Dragon Shoot: A move only seen in episode 16. The Dragon Shoot was taught by the Interpol Agent, Ryusuke Taki. Ryusuke threw the Ultra Quartz (a wanted object in the episode) towards Kamen Rider Black where he quickly jumped and kicked it with one foot.
• King Stone Flash: Perhaps the most powerful technique. By shouting out "King Stone Flash", Kamen Rider Black could fire a burst of energy from his belt. It worked every time to fend off the villains; whether it's the High Priests or even the powerful Shadow Moon
