This is NOT relating to leaks or anything already revealed for Legends: Z-A. This is just a list of concepts I had for new Mega Evolutions.
Mega Galvantula is based on a thundercloud, with static hairs all over its body that are like the hairs on Sandy Shocks. It also makes it look more like a tarantula. Its legs resemble lightning bolts coming from the cloud body. Its whole body is charged with static electricity, and its ability is Electric Surge.
Mega Crawdaunt is based on a pirate, with a bit of Team Aqua inspiration. Its right claw forms a hook, which is sharp and gives it the ability Tough Claws.
Mega Scovillain is frequently drawn with a third head, and while I think that could work for a final evolution, I feel like that's too drastic for a Mega Evolution. I instead chose to make it a more elementally split version of the original, with the red head gaining fire elements and the green head gaining plant-like elements. When the heads work in harmony, they can create sunlight, and their ability is Drought.
