I tried to find electric animals and all I got were fish. I couldn't even find the deathworm. Why are you looking for electricity anyway?
Well, as the death worm did influence quite a bit of my concept, I thought if I could find some kind of excuse for how it was exactly doing what it is; I guess I'm thinking far too ahead in this in trying to explain the pokemon's abilitys huh? lol
Anyways, here's my concept, kinda hybrid mix between many suggestions thus far; I originally thought of some kind of flying evil little poisonous thing, but when I realized that wasn't going to fly with a ground type (lol) that I should try to think otherwise. A flying, self-coiled snake came to mind with being pretty fast, and pretty utility in things. But since I decided against the flying-snake, I grounded it. Now, meet my Mongolian Death Worm/Arbok crossbred monster whose uncle is Drapion.
Snakelike, I figured a fast enough snake could spin itself to do a rapid spin, as well as, well being a fast poke (if the stats polls are any indication.) Snatch, Spikes, Toxic Spikes, Haze, and even with that (horribly angular incorrect) tail it could use Tailwind. The spines... I'm actually not sure what they CAN do, that's why I was looking for more information on real animals, see what electricity can do; as I see it, they're "sensors", which can affect the air around them slightly. Basically, a tool to get it to use this energy in the air which would allow it the use of the more spiritual moves; IE Safeguard, Wish, Gravity, etc. (magnetism for gravity BTW). Encore by clicking its mandibles (I can make them more mandible-like) and by clapping its legs together? :P
More on its design; it is very bug-like, yes I know that. But I have made it as non-bug as I could. I imagine it being the cousin of Drapion, this guy's pre-evo being like bug/ground or bug/poison; Bug group and Field/Ground group would be the egg groups. The foreclaws, legs, w/e have a shovel-like design to them because it IS ground; it uses them to dig. And I think I don't need to say how this thing is clearly venomous...
After feedback I'll change it or if it's good as it is I can clean it up better, unfortunately I do not have the means to color it though... (dunno about which should be which, between the top and bottom of the main body purple or brown; purple on top brown on bottom LOOKS best, but brown top purple bottom makes more sense, since the brown would be disguising into the ground more... oh and the legs/forearms are tan as well.)
