Another one of my recent Nega-Mega Evolution designs, with this one being requested by @Colleen.
When designing Nega-Mega Goodra, I wanted to something similar to my design of Nega-Mega Dragonite by taking this cute lovable gooey dragon and turning it into a horrifying monster. I started by looking at depictions of the Lou Carcolh (the giant serpent/snail from French mythology that Goodra was based on) and decided to give it more snail-like qualities than dragon-like qualities by having the lower half of its body split in two and coil up to make a large snail. I also gave it a leech-like mouth and had its eyes attach to its retractable horns/tentacles/antennae. Additionally, the pale-green slime that was once on Goodra's arms and chin would now cover most of its body, while new trails of slime would form where the green spots used to be.
I also incorporated the additional type I gave Nega-Mega Goodra into its design:
Nega-Mega GoodraLike some people, I originally thought Goodra would end up being part Poison type when it was first revealed instead of a pure Dragon type. Because of this, I decided to give Nega-Mega Goodra elements of a Poison type such as the massive amounts of slime and the acid drooling from its mouth. I also gave it Poison Point as its ability and drastically increased both its Physical and Special Defense, as well as its Special Attack, making it the ultimate tank (though it did lose some of its Speed).
Ability: Poison Point
