#HKO: Indicates a KO (defeat) in a specific number of hits. For example, 1HKO (or OHKO) means a one-hit win.

Accuracy: The inherent hit rate of a move, often expressed as a percentage (e.g., 80% for Stone Edge). This can be modified by in-game effects. Some moves bypass accuracy and evasion checks.

Attack (Atk.): A Pokémon's stat that influences the damage dealt by physical moves. Physical moves are typically of Normal, Fighting, Flying, Ground, Rock, Bug, Ghost, or Poison types.

Base Stat (BS): A Pokémon's inherent value for a specific stat, ranging from 1 to 255. Higher base stats generally indicate better performance in that stat. A value of 110+ is often considered good.

Base Stat Total (BST): The sum of all of a Pokémon's base stats, providing a general measure of its overall power. However, strategic value can be skewed by exceptionally high individual base stats.

Catch Rate: A hidden characteristic (1-255) determining the likelihood of catching a Pokémon, with 255 being the highest chance.

Class: An attribute of moves determining their nature and how their damage is calculated. The three classes are Physical (based on Attack/Defense), Special (based on Special stat), and Status (affects other things). In Generation I, this is primarily tied to the move's type.

Critical Hit (Crit): An attack that deals approximately double damage. Critical hits are declared in-game and are influenced by the Pokémon's Speed stat and certain moves with higher critical-hit rates (e.g., Slash). They ignore stat changes to Attack and Defense.

Defense (Def.): A Pokémon's stat that influences the damage taken from physical moves.
