Pigron

Pigron is a Hardmode monster found in Underground Biomes. They come in multiple colors and they have a special ability to turn "invisible". They don't actually turn invisible, only highly transparent, and can be seen on close inspection. As one starts to attack you, it will become visible again. In the invisible state they can fly through walls, and will continue to follow players until killed.

Trivia

 * The name is a portemanteau of the words "Pig" and "Dragon". This was confirmed by Cenx in the IRC.


 * They actually look very similar to Pommy Dragon from the game "Bomberman Tournament", it is unknown if they are related or not.
