|“||Wild Pokémon appear in the middle of the city to attack the fighters. It's best just to stay out of their way.||”|

This Pokémon city is extremely treacherous, so select a character with excellent jumping skills. Narrow crevices positioned between small platforms make it difficult to avoid falling. Random Pokémon pop out of the rooftop at timed intervals, and they will indiscriminately attack anyone in their way. It's best to proceed cautiously in these mean streets.
Saffron City has one main platform attached to a small platform above a door. To the right is a narrow platform and to the left are two elevators (moving platforms). Between these and slightly lower than the other platforms is yet another narrow platform. There are many gaps in-between that character and items can fall into. It is this feature, as well as the fact that it is a stage upon the tops of tall buildings, that makes it similar to the Fourside stage in Super Smash Bros. Melee and New Pork City in Super Smash Bros. Brawl.
In the Pokémon Center
Every so often the door of the Silph Co. building opens, and if a player approaches the open door a Pokémon will emerge to attack the player. If the door remains open long enough without any player approaching it though, the Pokémon attack will be triggered anyway. The five Pokémon that may emerge from it are:
- Chansey, tosses an egg which may contain an item. If items are turned off though, Chansey will not drop an egg. Chansey is the one Pokémon that will not attack players, but rather will heal 5% damage to characters who come into contact with it. Chansey can also be KO'd with a sufficiently strong attack, though there is no reward (or penalty) for doing this.
- Charmander, when he appears he may or may not breath flames similar to those from a Fire Flower. The flames deal 3% damage per burst, but since it is fired continuously there is little chance of escaping the fire stream before Charmander disappears. Coming into contact with Charmander itself will deal 5% damage to the player. Like Chansey, Charmander can be KO'd with strong attacks such as Kirby's Stone, Pikachu's Thunder, Donkey Kong's fully charged Giant Punch and Captain Falcon's Falcon Punch.
- Electrode, explodes a short time after appearing, dealing 30% damage and large amounts of knockback, KOing characters on higher damage. Cannot be KO'd.
- Porygon, lunges out very quickly, dealing 18% damage upon its appearance and 8% damage thereafter. Cannot be KO'd.
- Venusaur, deals 14% if touched and will sometimes use Razor Leaf to shoot out sharp-edged leaves, each dealing 3% damage. Cannot be KO'd.
Flying Pokémon, including Butterfree, Pidgey, Fearow, who may also be spotted in swarms in the background. Though it is very rare, Moltres, sometimes make its way across the background. Moltres is one of the easiest to spot of these Pokémon, as it is bright orange.
Saffron City made its first appearance in Pokémon Red and Blue. Saffron City is the largest city in the Kanto region, and one of the largest cities in the entire Pokémon universe. The main building of Saffron City, Silph Co., is a major producer of items to benefit Pokémon trainers, producing items such as the Master Ball and the Up-Grade, and it is the rooftop of this building that forms the main platform of the Saffron City stage. In Pokémon Red & Blue, the entire city was taken over by Team Rocket, mainly Silph Co. in order to obtain the Master Ball, the ultimate Poké Ball that will instantly catch any Pokémon, no matter what the circumstances are.
Saffron City is also unique in that it is the only city in Kanto to have two Pokémon Gyms, which function next door to each other; however, only one of them, headed by Psychic-type trainer Sabrina, is sanctioned by the Pokémon League, and therefore, it is where players can get the Marsh Badge. The other is home to Trainers who specialize in Fighting-type Pokémon, and is therefore called the Fighting Dojo. After the player defeats the strongest trainer in the Fighting Dojo, you receive either a Hitmonchan or a Hitmonlee. This is the only place in the Kanto games where those Pokémon can be obtained.
The music heard in this stage first originated from Pokémon Red and Blue's title screen.
- Ness cannot use his third jump as the turning circle of PK Thunder is wider than the gaps between the buildings, so it can't be directed underneath Ness to perform PK Thunder 2. This puts Ness at a considerable disadvantage, so in tournaments this stage cannot be selected as the first stage if one of the players uses Ness. It is then labeled as a counterpick.
- In Brawl, the final section of The Subspace Emissary stage Glacial Peak features an area similar to this stage except that the building shapes are made of ice.
- In Brawl and for WiiU, many people have used the stage builder to re-create this classic stage. For WiiU variations commonly use the lava tiles at the "elevator door" section to emulate the Pokémon hazards.
- CPU's often walk straight at the door even when it is closed, leaving themselves vulnerable to attack.
- In the Japanese version of the game, the Silph logo atop the building is written as "Silf".
- This, along with Lumiose City, is the only Pokémon Stage to be based on a City.
- This stage and Mushroom Kingdom both share the longest gap between appearances in the Super Smash Bros. series, with 19 years between Smash 64 and Ultimate.
