Electabuzz is a slightly humanoid creature with a few feline traits. It is covered in yellow fur with black stripes; a large stripe on its chest is shaped like a lightning bolt. It has a long tail. There are three, clawed toes on each of its feet, two in front and one in back, while it has five fingers on each hand. Electabuzz has two sharp fangs and a pair of antennae with bulbous ends.
In the dark, Electabuzz will glow light-blue, with the electrical charge stored inside of its body over long periods of time. It is constantly leaking more electricity than it consumes. During torrential thunderstorms, Electabuzz will compete to find locations likely to be struck by lightning in order to absorb the electric power. Electabuzz are often used as an alternative to lightning rods because it is unharmed by the absorption of electricity.
As demonstrated in the anime, Electabuzz is sent into a rage by the color red. In battle, Electabuzz windmills its arms, apparently to add momentum to its punches. This method of battle seems ineffective, as opponents can escape in the meantime. It is also capable of entirely nonverbal communication via electrical currents when in close proximity to another of its species. Electabuzz typically resides near power plants and can cause blackouts in cities, though it can also be found in grasslands.
An Electabuzz appeared in Current Events as the head of security in an electric company's power station. It attacked Ash and his Chikorita, believing them to be intruders, but it was then captured by Team Rocket. However, it was later freed.
An Electabuzz appeared in A Promise is a Promise, under the ownership of Dr. Namba. It wore a headgear that made it angry and thus increased the power of its attacks. Despite this, it was defeated by Pikachu and Sparky with a double Thunder attack.
Rudy's Electabuzz was his first choice of Pokémon in his Gym battle against Ash.
In the Pokémon Adventures manga
Electabuzz debuts in its own round, Buzz Off, Electabuzz!, under the ownership of Lt. Surge. It is so vicious that even its Trainer cannot keep it in its Poké Ball and its Thunder Punch attack tears through ground floors like wheat. Although the most that Poli can do against it at first is freeze its feet so that Red and Poli can flee, the tables turn when Poli evolves into Poliwrath and throws Electabuzz and its Trainer both off the ship. Electabuzz later appears to fight Morty's Misdreavus, but while its continuous Thunder attacks do a number of damage, the ghost's Pain Split and Spite leave it unable to attack.
Magmar and Electabuzz seem to be counterparts; both evolve in a very similar way (first at level 30, then after being traded holding an item which has a name that ends with the suffix "-izer"), and both are typically exclusive to one version of a pair of games. They both have similar status-inducing Abilities in Flame Body and Static, as well as the same Hidden Ability, Vital Spirit. Since Generation V, they also often learn similar moves at the same level. They even have the same special moves when purified in Pokémon XD: Follow Me and Cross Chop. Their pre-evolutions and evolutions were released in the same generation (Generation II and IV).
Electabuzz is the only member of its family not to have some physical relation to an AC power unit. Elekid's head is shaped like a power plug while Electivire's back pattern looks like a power socket.
Electabuzz is depicted with six fingers (five fingers and one thumb) on both of its hands in Pokémon Stadium.
Electabuzz is likely based on the Japanese oni that was a horned ogre that wore tiger skin and was sometimes depicted as a god of lightning and thunder. Its tail looks like that of a tiger.
Electabuzz is a combination of electric and buzz (possibly referring to the humming sound of electricity).
Eleboo may be a combination of electric and ブンブン bunbun (buzz).
