Unique Types
This is the only pseudo-legendary that has a type combination not shared by any other Pokemon.
Tyranitar
This is the signature move of the Garganacl line, giving a status effect which drains 1/8 of the opposing Pokemon's HP, or 1/4 if they are Water or Steel type.
Salt Cure
This is the signature ability of Unovan Yamask/Cofagrigus.
Mummy
Introduced in Gen VIII, this item allowed the holder to become immune to all entry hazards.
Heavy-Duty Boots
The absurd power of this Pokemon in the singles format caused the creation of a new tier, Anything Goes.
Mega Rayquaza
This is the only first partner that has a type combination not shared by any other Pokemon.
Empoleon
This is the Pokemon with the most signature moves, at five.
Zygarde
This Pokemon is the only non-Mega Evolution Pokemon to have the ability Pixilate.
Sylveon
Similar to Leftovers, this item can heal the holder, but only if they are a specific type. Otherwise, this damages them.
Black Sludge
In Gen I, this is the only evolutionary line with three 4x weaknesses to Fire, Flying and Poison.
Paras/Parasect
Introduced in Gen IV, this is the first Mono-Flying type Pokemon.
Arceus-Flying
This Pokemon's signature move caused it to be banned from any online tournaments before it was changed in Gen VI.
Chatot
The signature ability of Cinderace allows it to change its type to the move it was using.
Libero
Introduced in Gen V, this item removes the holder's type immunities.
Ring Target
Aside from the Eeveelutions, this Pokemon is the only one that does not share any types with its pre-evolution.
Alolan Marowak
This evolutionary line is the only line to keep its unique typing since Gen I.
Zubat/Golbat/Crobat
This is the only Pokemon with the move Doom Desire.
Jirachi
This Pokemon has the ability Mycelium Might, this enabling the user's status moves to ignore abilities, but at the cost of moving last in its priority bracket.
Toedscool/Toedscruel
This plate item was the only one of its kind to be obtainable in Sword and Shield. Arceus was not obtainable in this game, making its appearance more peculiar.
Pixie Plate
Prior to Gen IX, this is the only Pokemon that loses a type when Mega-Evolving.
Aggron
This is the only type combination that can be found within Pokestar Studios, and nowhere else.
Normal/Steel
This move can only be used by Mew.
Genesis Supernova
This is the only Pokemon with the ability Neuroforce, only appearing in one pair of games.
Ultra Necrozma
This obscure held item was only seen in Gen II, raising the user's Attack by 2 stages, but confusing them.
Berserk Gene
This Gen V Pokemon is the only Bug-type to have won a World Championships Title in the Masters Division.
