Goldeen

Goldeen (, Tosakinto in Japanese language versions) is a creature in the Pokémon media franchise.

This is a Poké Ball Pokémon that appears in all three Smash Bros. games, which is a rarity, because the only other known such Pokémon are Electrode*, Mew, Snorlax, and Charizard**.
 * Electrode doesn't appear from a Poké Ball in SSB, but rather as a stage hazard in Saffron City.


 * Charizard appears in all three, it makes its debut as a playable character in Brawl instead of coming out of a Poké Ball.

As a Poké Ball Pokémon
Goldeen appears as a Poké Ball Pokémon in Super Smash Bros. It flops around on the stage helplessly until it disappears or has fallen off the stage. It is one of two completely harmless Pokémon in the series, the other being Mew. Goldeen does not have any hitboxes; none of its attacks give damage to any of the characters. Thus, it is established as the "dud" Pokémon of the Smash Bros. series.

As a Poké Ball Pokémon
Goldeen returns in Super Smash Bros. Melee to reprise its role exactly as something that does not affect gameplay in any way.

Starting here, rumors have flown around the Internet claiming that under certain conditions, Goldeen will activate Horn Drill and instantly KO an opponent. Although this has never been completely proven or disproven, most people accept it as false, due to a lack of evidence beyond a glancing mention in the Melee trophy. Surprisingly, Goldeen does nothing special on stages with water. However, if Goldeen touches water instead of just sinking like most Pokémon it will swim underwater then disappear.

As a stage element
A larger balloon of Goldeen (in actuality, the 3D model of Goldeen used in Pokémon Stadium for Nintendo 64) is one of the many floating and moving "platforms" that comprise the Poké Floats stage.

As a trophy
Goldeen features as a collectible trophy, unlocked as one of the 100+ trophies that can be collected randomly during normal play, such as in the Trophy Lottery, and throughout the various Single-Player game modes. It reads as follows:

''A Goldfish Pokémon. In contrast to its elegant appearance, it has a wild temperament, and its attack with its horn is severe. Among the techniques it can master, Horn Drill is especially reliable. It evolves into Seaking, but if it's raised without evolving, it can learn the powerful Bug-type move Megahorn. There are male and female Goldeen--the male's horn is longer.''

As a Poké Ball Pokémon
Goldeen returns in Super Smash Bros. Brawl, and is, once again, a "dud" Pokémon. The description on the Dojo tells the player to watch out for Murphy's Law (whatever can go wrong, will) when using Poké Balls, showing Goldeen's picture.
