One of the comments I've received in regards to my particular vision of Electabuzz is that they're far more slender and streamlined than the 'official' vision. My explanation for that mostly stems from the dual omnivorous/ergovorous nature of their diet. Electabuzz do require organic nutrients as a source for base materials, but another source of nourishment for them is derived from a form of electrochemical synthesis which they fuel through the absorption of electric charges.
There is, however, such a thing as too much of a good thing. In the wild, Electabuzz get most of their massive 'power boosts' from atmospheric charges - predominantly, lightning storms - and most of the charge they acquire naturally dissipates over time due to use in communication or attacks. Human-made power sources made electricity far more available for groups of Electabuzz than it would normally be, in relatively continuous input as opposed to large, momentary bursts - leading to the creatures being drawn to these power sources and gorging themselves on electricity beyond the amount they would need to normally feed on, with much less activity required to get at it.
So it's essentially become McDonald's for Electabuzz. It all went downhill from there. And all the 'buzzes you find in-game are found in the general areas of power plants. I think you can see where I'm going with this.
However, not all is peaceful for these larger, gorged-on-electricity 'Buzzes - battles still occur, and on occasion, Buzzes aren't the only species involved. In this picture we see a male specimen fending off a swarm of Magnemites...
