In the [[version|main series]], Shiny Pokémon were first introduced in [[Generation II]]. This was likely to take fullest advantage of the [[Game Boy Color]], which enhanced {{2v2|Gold|Silver}} and was required for {{game|Crystal}}.

When a Shiny Pokémon appears in the wild or from a {{pkmn|Trainer}}'s [[Poké Ball]], stars will surround it and make a pinging sound effect (in {{game|HeartGold and SoulSilver|s}} this will also happen if a wild Shiny Pokémon breaks out of the Poké Ball). In Generation II, this ping happens before the Pokémon's cry, while from [[Generation III]] onward, it occurs afterward. In [[Pokémon Stadium 2]] and [[Pokémon Battle Revolution]], a flash of light circles the Pokémon upon its release from the Poké Ball. On the Pokémon's status screen, its Shiny status is indicated in Generation II as three small stars beside its gender, as small yellow star in {{game|FireRed and LeafGreen|s}}, in [[Pokémon Stadium 2]] as yellow star that animates from bright to dim, and in Generations IV and V as a large star near its picture. In {{game2|Ruby|Sapphire|Emerald}}, the Pokémon's [[Pokédex]] number will also be colored gold instead of black, whereas in Generations IV and V, the number will be colored red. In {{game2|Ruby|Sapphire|Emerald}}, the background behind the sprites of Shiny Pokémon is white instead of gray, and small purple squares are added to corners. In {{game|FireRed and LeafGreen|s}}, the border with [[gender]], [[nickname]], and [[level]] will be {{Color|68E0E0|teal}} instead of {{Color|C8A8E8|purple}}.

In Generation II, Shininess is determined by the {{IV}}s of a Pokémon. If a Pokémon's Speed, Defense, and Special IVs are 10, and its Attack IV is 2, 3, 6, 7, 10, 11, 14 or 15, it will be Shiny. This determination allowed for compatibility with [[Generation I]], as if a Shiny Pokémon is traded back, then traded forward, it would retain its Shininess. Despite the bonus of backward compatibility allowing for a Shiny Pokémon to learn Generation I [[TM]]s, provided it was a Generation I Pokémon, Shiny Pokémon are only slightly above average in terms of IVs.

Due to the probability of the IVs lining up in any of these manners to produce a Shiny Pokémon, the chance of obtaining one in Generation II is approximately 1/8192. However, if one breeds a Shiny Pokémon properly, the offspring may have as high as a 1/64 chance of being Shiny, depending on the species of Pokémon.
Due to the HP IV being determined by the other four IVs, a Shiny Pokémon's HP IV can only be 0 or 8. This is because HP takes the final binary digit of the Attack, Defense, Speed, and Special IVs and places it, in that order, for its own IV. The last 3 binary digits are always 0 because those IVs have to be 10 (1010 in binary) for Shiny Pokémon. The first digit depends on whether or not the Attack IV is even (then it is 0) or odd (then it is 1). This means that the HP IV can either be 0000 (0) or 1000 (8).

Shininess is inherent to an individual Pokémon; that is, a Pokémon that starts out Shiny will always be Shiny, and one that is not will never be (provided its data is not altered through [[cheating]]). Upon evolution, a Pokémon will retain its Shiny status. A Shiny {{p|Charmander}}, if leveled up, will eventually become a Shiny {{p|Charmeleon}} and then a Shiny {{p|Charizard}}, just as a regular Charmander will become a regular Charmeleon and then a regular Charizard. This is due to the status being determined by values inherent to the Pokémon; however, there is a [[Personality value|difference]] in the determination between Generation {{gen|II}} and Generations {{gen|III}} to {{gen|V}}.
