Barugaron is an alien monster/daikaiju that appeared in the game Godzilla Trading Battles.
Barugaron arrived on Earth, searching for blood to feed upon. After eventually feeding on Godzilla's blood, the creature transforms into the form it appears in the game as.
In its new form, Barugaron appears very much like a dinosaur and has a slight resemblance to Godzilla - due to feeding on his blood and inheriting his traits as a result. It has three claws on its hands, two on its feet, many horns on its face and some spikes on its knees, as well as a row of spines (or scutes) on its back - all of which are yellow in colour.
In regards to its powers, Barugaron can feed on blood and change its form according to it. Barugaron's other special ability is to spit a corrosive acid-like substance, similar to fellow monster Biollante. He could also absorb oil to regenerate.
