Bleuetium is a lightweight solid element (29 u) that seems to not really have an oxidation limit. It has a smell similar to that of blueberries. It can hold five oxygen atoms (at least six when in close proximity to Nitrogen), at least two sulfur atoms, at least three bromine atoms, at least four fluoride atoms, and less than 250 hydrogen atoms (I tried to take a picture of Bleuetium Dictapentacontahydride, but it destabilized the hydrogen atoms before I could). It could also eat a grain of uranium, explode, and survive said explosion. It also likes to be close to Nitrogen (one of many elements it can't eat) and he can eat more atoms when close to Nitrogen. Bromine is its favorite food. Also, even if it's not heavy enough to explode, it can still explode if it don't like the element to "consumes". In fact, his discoverer, Nathan Webber, assumes that it may not even be an element but a "tiny creature". Eventually, it was confirmed to be both an element AND a creature.
