OHKO

OHKO, an acronym for "One Hit Knock Out," is a popular challenge run modifier in many role-playing games, particularly those from the Pokémon franchise. The core principle of an OHKO challenge is that the player must defeat every opponent in a single turn or a single attack. This requires meticulous planning, strategic team building, and often a significant amount of luck.

Players undertaking an OHKO challenge typically focus on Pokémon with moves that inflict instant defeat, such as Fissure, Guillotine, Horn Drill, or Sheer Cold. These moves have a low base accuracy, making the challenge significantly more difficult as their success is not guaranteed. The player must also consider the opponent's Pokémon, ensuring their chosen strategy is effective against a variety of types and abilities.

The rules of an OHKO challenge can vary. Some players adhere to a strict definition where only the player's Pokémon can land a one-hit knockout, while others allow opponents to achieve the same. Some challenges extend the "one hit" rule to the player's Pokémon, meaning if their Pokémon are hit by an attack that would knock them out, the challenge fails, regardless of whether it was a one-hit knockout or not. This adds another layer of difficulty, requiring players to prioritize defensive strategies or the ability to outspeed and defeat opponents before they can retaliate. OHKO runs are often documented and shared online, with players discussing strategies, showcasing their successes, and lamenting their failures.
