Frogs are such an interesting type of animal, and Toxicroak is an interesting Pokémon. Hence why Toxicroak got a Mega during Mega Month. I gave it more poisonous elements across it's body, since it retains more, stronger toxins.
If the large claws weren't obvious enough, Mega Toxicroak was inspired by the hairy frog, also known as the wolverine frog, a frog that uses it's own broken bones as claws. Seriously, look it up, that's insane.
