WIP
This was a hard combo, I gotta admit. I struggled for quite a bit to make something work, which would not have been a good sign in most cases, and I'm still pretty sure the secondary ability will have a good chance of ruining it. Luckily, I've managed to make a design that works well enough for what's there so far! I think...
The main two inspirations for this big bug were
Arthropleura, a gigantic Carboniferous millipede, and
Nidhogg, the dragon that lives under the World Tree of Yggdrasil in Norse mythology. At around 2.5 meters (8.2 feet) long,
Arthropleura was one of the largest terrestrial invertebrates known, so compared to cousin Scolipede, who's already pretty massive, I imagine this guy might well be as big as Onix, or even bigger. Now, what does Nidhogg have to do with this? You see, one of the best-known parts of his legend is that he chews on the roots of Yggdrasil in a bid to topple the tree over - either that, or chewing on the deceased bodies of the most depraved in life. I went with the root-eating bit because
Arthropleura was likely herbivorous, which we know thanks to gut contents known from it largely consisting of plant life, so there's actually a justification for the root-munching lore in this case. That said, just because this thing can't eat you doesn't mean it can't kill you, and this being a Dragon-type I gave it a menacing appearance in the vein of Yanmega, with large fangs and sharp teeth for mincing plant food and attackers' limbs alike,
Stegosaurus-like plates on the back like those on Yanmega, and a head plate slightly resembling a Viking warrior's helmet.
Now, as for the abilities and stat spread...
Arthropleura is believed to have been quite quick despite its size thanks to analysis of fossilized trackways, which fits the Speed being pretty solid, though not great thanks to its size. The fangs and bladed spines already hint at high physical attack, but because this is an anti-pivot 'mon, I also styled the latter to suggest a picket fence (though I may have to make that clearer further down the road), and I can easily see it encircling its opponent, literally fencing it in and keeping it from escaping. The justification for both the almost as high Special Attack and Neutralizing Gas is the vapor pouring from the vents on the sides of its head and body along with the tips of its tail and antennae/horns. Many species of millipedes actually release toxic vapors such as cyanide as a defense, and turning this into an offensive technique was the next logical step, seeing as many European dragons were said to emit toxic fumes. As for the low defenses, one idea I originally had was the addition of a weak spot on the underbelly, a glowing marking that could be struck easily, but that seemed out of place after I tried putting it there. Then I realized that I could tie it into the vapor by having it come out of permanently open spiracles which would allow weaponry and energy attacks to easily enter and harm its insides, which gets the idea across but makes more thematic sense. Finally, I was originally going to color this thing pink like a pink dragon millipede, but after fiddling with the color scheme I found that this purple and blue palette works much better, especially with the green vapor like I'd always intended.
I'll fiddle around with this a bit more when I get the time (I particularly want to make the plates even more fence-shaped), but I'm happy with how this turned out, so hopefully it won't take too long to proceed to the shading! ^_^
