Random Gen 4 Pokémon Generator (Sinnoh)
This generator picks a random Pokémon from the 107 species introduced in Generation IV, the Sinnoh generation. The list runs in National Pokédex order from Turtwig to Arceus, and every species first discovered in this generation is included, from the starters to the Legendary Pokémon.
Gen 4 began with Pokémon Diamond and Pearl, first released in Japan in 2006. For many players, the Pokémon of a single generation are tied to a particular console, a particular region map, and a particular time in their lives. That makes a Gen 4 picker a quick way to revisit favourites, discover species you skipped, or set up a challenge that stays true to the Sinnoh era.
Each result is a species, not an alternate form. Regional variants and other forms added in later games are counted under the generation where the species first appeared. If you want Pokémon from every generation at once, the Random Pokémon Generator covers the whole National Pokédex, and the Legendary and Starter generators focus on those groups across every region.
Trainers in Pokémon Diamond and Pearl choose their first partner from three starter Pokémon: Turtwig, Chimchar and Piplup. As in every generation, the three cover Grass, Fire and Water, so each one is strong against one of the others and weak to the third.
14 Legendary and Mythical Pokémon debuted in Gen 4: Uxie, Mesprit, Azelf, Dialga, Palkia, Heatran, Regigigas, Giratina, Cresselia, Phione, Manaphy, Darkrai, Shaymin, Arceus. Legendary Pokémon usually appear once per game as part of the story, while Mythical Pokémon have mostly been given out through special events.
Sinnoh is based on Hokkaido, Japan's northern island, and is known for its snowy north and the towering Mt. Coronet that splits the region in two. Its myths concern the creation of time and space. Brilliant Diamond and Shining Pearl remade it, and Legends: Arceus visited its distant past as Hisui.
Of the 107 Pokémon introduced in this generation, 54 have a single type and 53 have two. These types appear most often:
Limiting yourself to the 107 Pokémon of Gen 4 is a popular way to relive the Sinnoh games or to give a newer game a fresh challenge. Decide early whether Pokémon that gained a new evolution in a later generation may evolve past their Gen 4 form, and whether the Legendaries are allowed. With 53 dual-type Pokémon in the list, rolling a few extra candidates and picking the ones that cover each other's weaknesses makes a balanced team much easier to build.
