Pokémon Physiology

Introduction

Pokémon, known in Japan as Pocket Monsters, are fictional creatures that serve as the foundation of the Pokémon franchise. New species are frequently introduced alongside the release of new games and related promotional material.

In the context of the Pokémon universe, the term "species" is used differently than in real world biology. In nature, a species typically refers to a group of organisms capable of producing fertile offspring, which does not align with how Pokémon breeding works. Additionally, real organisms do not change from one species to another, whereas Pokémon can undergo Evolution—a process that more closely resembles growth, development, or metamorphosis rather than biological evolution.

Each species has a capitalized name, such as "Pikachu." The species name is often used in the singular form to refer collectively to all members of that group, for example, "Pikachu is an Electric-type Pokémon." The plural form remains the same as the singular, such as "two Pikachu." In some early Pokémon media, incorrect plural forms like "Digletts" occasionally appeared.

Individual Pokémon are typically referred to by their species name as well, for instance, "Pikachu used Thunder Shock." However, some individual Pokémon are given nicknames instead.

In Japanese, Pokémon species names are written in katakana and also have official romanized forms. For example, Onix is written as イワーク (Iwark) in Japanese.

Weaknesses

• Pokémon being greatly angered causes them to be confused.
• The usage of struggle makes the Pokémon take recoil damage, even if they've barely damaged an opponent.
• Pokémon become too scared to move when dealing with an entity that cannot be ID'd.
• One Hit KO Moves do not work if the opponent is higher leveled.
• Startling a Pokémon in the middle of its evolution will cause it to not evolve.

Notes

• In Generation 1 games, struggle was a normal type move that didn't work on ghost Pokémon and would do basically no damage to enemies that were resistant to such attacks however in Generations 2 and onward, struggle was a typeless move that did neutral damage to all Pokémon including ghost types. This effectively means the mechanics of struggle were soft retconned after generation 1 along with many of its other mechanics.

Explanations

Status Effects

The following is an explanation of the various status effects of Pokémon

Status Effects

Name Effect Apperances Burned Reduces one's physical attack and takes damage overtime from the burns. Usually caused by Fire type moves and generally lasts indefinitely unless an external item, ability like shed skin, or move like rest is used. In Generation 1, a burned Pokémon takes damage equal to 1/16 of its maximum health. In Generation 2, a burned Pokémon takes damage equal to 1/8 of its maximum health. In Generation 8 onward, a burned Pokémon takes damage equal to 1/16 of its maximum health. Burn status can be caused by the following moves: Beak Blast (if a Pokémon makes contact with the user of the move during the move's charging phase), Blaze Kick, Blazing Torque, Blue Flare, Burning Bulwark (If contact is made with the user of the move), Burning Jealously (If the Pokémon has increased stats during that turn), Ember, Fire Blast, Fire Fang, Fire Punch, Flame Wheel, Flamethrower, Flare Blitz, Fling (if holding a Flame Orb), Heat Wave, Ice Burn, Infernal Parade, Inferno, Matcha Gotcha, Lava Plume, Psycho Shift (If the user of the move is already inflicted with the burn status), Pyro Ball, Sacred Fire, Sandsear Storm, Scald, Scorching Sands, Searing Shot, Secret Power (when used on a volcano), Shadow Fire, Sizzly Slide, Steam Eruption, Tri Attack, and Will-O-Wisp. Most Pokémon Games Freeze Prevents any action in battle. Usually caused by Ice type moves and generally only lasts for multiple turns, they can be thawed out early if hit by a fire move. The thaw out chance ranges from generation, in Generation 2 the thaw out chance is a 25/256 chance. In Generation 3, the thaw out chance is 20% each turn. In Pokémon Champions, the thaw out chance is 25% each turn. In Generation 1, a frozen Pokémon cannot break out unless hit by a fire-type move that can inflict burn or if an opponent uses the move Haze. Frozen status can be caused by the moves: Blizzard, Freeze-Dry, Freezing Glare, Ice Beam, Ice Fang, Ice Punch, Powder Snow, Secret Power (when used in snow or ice weather), Shadow Chill, or Tri Attack. Most Pokémon Games Frostbite In Pokémon Legends: Arceus, the freeze status conditions is replcaaed with frostbite. Frostbite has the Pokémon lose 1/16 of their maximum health every turn and reduces damage dealt by a frostbitten Pokémon's special moves. Pokémon Legends: Arceus Paralysis Has a chance of preventing any action in battle and lowers speed stat. Usually caused by Electric type skills, it lasts indefinitely without external help, any ability like shed skin, or a move like rest. In later games, attacking a shocked enemy is guaranteed to cause a critical hit. Paralysis in general has a 25% chance of having a Pokémon be unable to attack asides from Pokémon Champions. In Generation 1, paralysis reduces a Pokemon's speed by 75% rounded down due to a stats modification glitch (along with this, using moves like agility would return the dropped speed to normal and double it and the speed drop would stay even after being cured of Paralysis using an item or through Rest). In Generation 2, the irregularities are fixed. In Generations 7 and 8 the paralysis reduces the Pokémon's speed by 50%. In Pokémon Legends: Z-A, the paralysis is changed to reduce the affected Pokémon's movement speed during battle. In Pokémon Champions, paralyzed Pokémon have a 12.5% chance to be fully paralyzed. The ability to paralyze can be done by the following moves: Body Slam, Bolt Strike, Bounce, Buzzy Buzz, Combat Torque, Dire Claw, Discharge, Dragon Breath, Fling (if holding a Light Ball), Force Palm, Freeze Shock, G-Max Befuddle, G-Max Stun Shock, G-Max Volt Crash, Glare, Lick, Nuzzle, Psycho Shift (if user of the attack is already paralyzed), Secret Power (When used on plain terrain, building floors, link battles, Sky Battles, Distortion World, or Electric Terrain is in effect), Shadow Bolt, Spark, Splishy Splash, Stoked Sparksurfer, Stun Spore, Thunder, Thunder Fang, Thunder Punch, Thunder Shock, Thunder Wave, Thunderbolt, Tri Attack, Volt Tackle, Wildbolt Storm, and Zap Cannon. Most Pokémon Games Poison Depletes health at the end of each turn, often persisting on the field. In Generation 1 a poisoned Pokémon takes damage equal to 1/16 of their maximum health at the end of every turn. A badly poisoned Pokémon still takes 1/16 of their maximum health at first, however the damage increases by 1/16 each time it takes poison damage. In Generation 2, the damage is lowered to 1/8 of its maximum damage and poison damage taken by a badly poisoned Pokémon doesn't interact with other types of recurrent damage. From Generation 1 to 4 all poisoned Pokémon in a trainer's party loses 1 HP for every four steps taken (in FireRed and LeafGreen it's instead every five steps). In Generation 1 to 3, the poison Pokémon will take poison damage until they faint. In Generation 4, a poisoned Pokémon's HP will be brought to 1 and then they will cure themself of poison. In Generation 5 to 8 poisoned Pokémon no longer take poison damage outside of battle. In Legends: Z-A, poisoned Pokémon take damage whil it is outside its Poké Ball. The moves that inflict poison are as follows: Baneful Bunker (If Pokémon makes contact with the user of the move), Barb Barrage, Cross Poison, Dire Claw, Fling (if holding Poison Barb), G-Max Befuddle, G-Max Malodor, G-Max Stun Shock, Gunk Shot, Mortal Spin, Noxious Toruqe, Poison Gas, Poison Jab, Poison Powder, Poison Sting, Poison Tail, Psychco Shift (if the user of the move is poisoned), Secret Power (When used in tall grass), Shell Side Arm, Sludge, Sludge Bomb, Sludge Wave, Smog, Toxic Spikes, Toxic Thread, and twineedle. Most Pokémon Games Confusion Confused Pokémon become indecisive and may either attack a random enemy or attack themself. In Generations 1-6 it was a 50% chance of the Pokémon hurting itself in confusion. In Generation 7 and onwards, it was a 33% chance of the Pokémon hurting itself in confusion. In Legends: Z-A, confusion causes the Pokémon to move sporadically. The following moves cause confusion: Axe Kick, Chatter, Confuse Ray, Confusion, Dizzy Punch, Dynamic Punch, Flatter, G-Max Gold Rush, G-Max Smite, Hurricane, Magical Torque, Psybeam, Rock Climb, Secret Power (only when used on a rocky surface), Shadow Panic, Signal Beam, Strange Steam, Supersonic, Swagger, Sweet Kiss, Teeter Dance, and Water Pulse. Most Pokémon Games Infatuation Infatuated Pokémon have a chance of not attacking the Pokémon they're infatuated with. There is a 50% chance of the move failing due to infatuation. The following moves cause infatuation: Attract and G-Max Cuddle. Most Pokémon Games Flinch The Pokémon flinches from an attack, costing them their turn.

In Generation 1, sleep lasts for 1-7 turns, with a 1/4 chance to wake up turn 1 and a 1/8 chance to wake up in 2-6 turns. In Generation 2 sleep lasts 2-8 turns, the Pokémon has a 1/4 chance oto wake up in 2 turns or 5 turns and a 1/8 chanc eot wake up in 3 turns, 4 turns, 6 turns, or 7 turns. In Generation 3 sleep lasts 2-5 turns. In Generation 5, sleep now lasts 2-4 turns. In Pokémon Champions, sleep now lasts 2-3 turns. The following moves cause sleep: Dark Void, Dire Claw, G-Max Befuddle, G-Max Snooze, Grass Whistle, Hypnosis, Lovely Kiss, Psycho Shift (if user is asleep), Relic Song, Rest, Secret Power (only in long grass, tall grass, or grassy terrain being in affect), Sing, Sleep Powder, Spore, Wicked Torque, and Yawn. Most Pokémon Games Drowsy The replacement for the sleep status in the Legends games. It has a chance of the afflicted Pokémon being unable to move along with taking increased damage from attacks. Pokémon Legends: Arceus and Pokémon Legends: Z-A Fainted Can no longer participate in battle. In most games, if the all Pokémon faint, the trainer whites out and returns back to their last save with some of their money gone. Can only be recovered with revives, healing at a bed or Pokémon Center, or through specific moves. Most Pokémon Games Wrap Prevents any action from a unit until the wrap ends. Pokémon Generation 1
