Mewdra shoots bubbles from its mouth to annoy swimmers who dive into the waters where it lives, and keeps doing so until they leave. When the battle gets tough, it takes on the appearance of its opponent to make them let their guard down.

The poisonous barbs all over its body are highly valued as ingredients for making traditional herbal medicine. A Mewdra is said to possess the genes of all Pokémon.
