Type: Grass
First Appearance: Pokémon Gold/Silver (1999)

Details:
Bellossom makes a welcome return from Melee. Using the same attack as in Melee, Sleep Powder, Bellossom dances around for a short time releasing a decent powder around it. This powder will put any player who comes in contact with it to sleep temporarily. It's likely they will wake up during it, to which if they don't quickly get out, they will wind up falling back asleep. As the summoner is unaffected by the powder, this makes the opponents ripe for a quick attack.

Type: Rock
First Appearance: Pokémon XD: Gale of Darkness (2005)

Details:
Bonsly makes his first Smash Bros. appearance in Brawl. Bonsly however is ever docile and once released from the Pokéball, will simply walk around. This is where the summoner and the other players come in. As Bonsly is walking around, any character can pick him up. Once picked up, albeit slowing people down due to his weight, the opponents can throw Bonsly a short distance. If Bonsly comes into contact with any enemy, it will cause decent damage and knockback. So be sure to be the one to get to it

Type: Psychic/Grass
First Appearance: Pokémon Gold/Silver (1999)

Details:
Celebi makes another appearance following his Melee debut. Unlike in Melee, Celebi doesn't do nothing. Instead, he does nothing with style! Once released, like before, Celebi will start floating up and away. However, this time, when it flies away, he will drop trophies to the ground for you to collect. Very handy for your collection, although it has been known to drop these trophies down holes

Type: Grass
First Appearance: Pokémon Gold/Silver (1999)

Details:
Chikorita makes a welcome return as well, utilising the same attack as in Melee; Razor Leaf. Once released from the Pokéball, Chikorita will take up position and start shooting out sharp leaves directly in front of it. These leaves damage and trap anyone on them if they come from above. They also have decent knockback and if a player is caught in one on the ground, they will likely be subjected to the full arsenal. However, they are reflectable if your character has means to reflect so don't be afraid to use it

Type: Psychic
First Appearance: Pokémon Ruby/Sapphire (2002)
This Incarnation: Pokémon FireRed (2004)

Details:
Deoxys makes his first Smash Bros. appearance in his Attack form. Following true to his form name, as soon as released from the Pokéball, it will fly up to the the top centre of the stage and will fire a massive beam down towards the stage. If anyone is hit by it, they will take massive damage and be sent flying, so its best to avoid the middle if you can. Although, if you're sneaky, you can boot an enemy into it, using it to your full advantage

Type: Electric
First Appearance: Pokémon Red/Green (1996)

Details:
Electrode makes an appearance identical to his previous Melee appearances, just with a slight twist. Once it is released, it will sit around for a while charging up.

While it's flashing however, you can pick it up and throw it at an enemy. Unfortunately, in Brawl, Electrode can sometimes fail to explode

Type: Water
First Appearance: Pokémon Red/Green (1996)

Details:
Goldeen makes its third appearance in the Smash Bros. series by doing exactly the same as the previous games. All Goldeen does is Splash around the stage, doing no damage to any character so it's essentially a waste of an item.

Type: Ground
First Appearance: Pokémon Ruby/Sapphire (2002)

Details:
Groudon makes it's first appearance in Brawl and with it, it makes a giant impression. Once released, it stays still, but due to its size it takes up a massive amount of most stages. Using its powers as the Continent Pokémon, it overheats itself making it deadly to anyone who touches it, which will be almost everyone considering his size. Despite the fact he is stationary, Groudon does move his head, arms and tails a bit so you have to be prepared for that

Type: Poison
First Appearance: Pokémon Ruby/Sapphire (2002)

Details:

First Appearance: Pokémon Ruby/Sapphire (2002)

Details:
Jirachi makes it's first Smash Bros. appearance here. However, like its other "un-obtainable" Pokémon friends of Mew & Celebi, it does not do any damage.

Jirachi drops Stickers down to the ground for you to collect

Type: Water
First Appearance: Pokémon Ruby/Sapphire (2002)

Details:
Kyogre makes its first appearance and in it, it is probably the least harmful yet most deadly Pokéball Pokémon in the game. Once sent out, Kyogre will pick an opponent to go for and move over to them. Once it finds it, it will should out water at them. This water is not harmful but does push the opponent. However, Kyogre slowly moves downwards once it starts shooting and as such can easily pin you down and push you off the edge. Although Kyogre's water is not harmful, if you touch its body, you will receive damage

Type: Dragon/Psychic
First Appearance: Pokémon Ruby/Sapphire (2002)

Type: Water
First Appearance: Pokémon Diamond/Pearl (2006)

Details:
Manaphy makes it's first Smash Bros appearance in Brawl, and like it's other "un-obtainable" Pokémon friends, it's quite rare. That said, unlike them, Manaphy actually uses an attack. Once released, he will fly up towards the top of the stage and use its Heart Swap move. This move will temporarily cause you and your opponents to swap bodies. You keep the damage and stock, but you have access to the enemy's attacks and possibly even Final Smash if its timed right

Type: Normal
First Appearance: Pokémon XD: Gale of Darkness (2005)

Details:
Munchlax makes its first appearance in Brawl and as such, its appearance is rather an annoying one. Once released from the Pokéball, Munchlax will walk around the stage, doing no damage to anyone it comes into contact with. However, if it sees an item, it will go up to the item and eat it. Very annoying if its sent out near an item you want to get

Type: Normal
First Appearance: Pokémon Gold/Silver (1999)

Details:
Togepi re-appears in Brawl utilising the same attack it has used in the past. Using metronome, a variety of attacks can happen. Night Shade has Togepi turn the stage completely black for a short time. Leech Seed puts a flower on top of the opponent's head, causing gradual damage. Hypnosis has Togepi send out a small shockwave and anyone caught in it will fall asleep. Icy Wind has Togepi freeze any nearby opponents and Earthquake embeds nearby enemies into the ground.
