Electrode (マルマイン, Marumine), is a fictional creature in the Pokémon series.
As a stage element
Electrode made its debut to the Smash series in Super Smash Bros., appearing as one of five Pokémon hazards on the stage Saffron City. The Electrode in Saffron City will pop out from the door on the side of the building when a character approaches. Electrode then will use Explosion as its attack after a few seconds of its appearance. Any character that is caught in the blast radius of Electrode will take damage and massive knockback.
As a Poké Ball Pokémon
Electrode returns in Super Smash Bros. Melee, this time as a Poké Ball summon, using Explosion once again. When Electrode comes out of the Poké Ball, it remains still, but will start to get darker over a period of a few seconds: this serves as warning that Electrode is about to explode. When Electrode explodes, everyone in the blast radius (including the character who summoned Electrode) will take heavy damage that is almost equal to a Bob-omb, and can KO characters even at low percentages. When Electrode is about to explode and starts to static it can be picked up and thrown. The character holding Electrode must be fast when disposing it, as their throwing animation has more startup lag, making characters with larger throw delays (such as Marth and Bowser) have a smaller window of safety. Electrode also appears in the event match Bomb-fest as the only Poké Ball Pokémon.
Electrode features as a collectible trophy, unlocked as one of the trophies that can be collected randomly throughout the various Single-player Regular Matches.
As a Poké Ball Pokémon
Electrode keeps its Melee function. However, this time there is a chance that it will fail to explode, disappearing shortly after without any effect. In this case it can be picked up and thrown: when a thrown Electrode collides with the ground or another player it explodes, and when smash thrown it can OHKO nearly any character but the super-heavyweights (Bowser, Donkey Kong, Snake, and King Dedede). Occasionally it just appears to fail, only to explode a few seconds later.
Electrode returns in Super Smash Bros. 4, reprising its role from Melee and Brawl. It is also the only Poké Ball Pokémon who is able to OHKO.
Electrode is an Electric-type Pokémon introduced in Generation I. It evolves from Voltorb starting at level 30, and, like it, it sometimes disguises itself as a Poké Ball and attacks unwary trainers which try to pick it up.
Explosion is a Normal-type move introduced in Generation I. With 250 base power it is in normal conditions the most powerful attack in the series, but has the severe drawback of making its user faint. Electrode can learn it in every game.
