In the popular children's TV show Avatar: The Last Airbender , the four nations that inhabit the world can each telekinetically control one of the four classical elements: water, earth, fire and air. One person, the avatar, can control all four elements and is markedly more powerful than any other character. Dmitri Mendeleev is the creator of the modern periodic table, which categorizes the 118+ atomic elements by their atomic number.
The comic is comparing the control over more magical power with more practical, "science-y" power. Fire, boulders, and storms may be more impressive visually, but science has proven time and again the "boring" can have very practical, very deadly applications. Additionally, while the advantages of controlling the four alchemical elements are mostly physical and visible (characters in the show most often use their powers to push, throw, or create barriers), the phenomena related to Mendeleev's elements and his research include subatomic particle interactions. One power the depicted Mendeleev has that the Avatar definitely does not have is control over radioactive elements, and this is the subtle, slow-acting power he demonstrates.
Polonium gained a level of notoriety as the poison used to kill Russian dissident Alexander Litvinenko .
The title text talks about power levels of the elements if each element had a controlling nation as per the TV show. Ununoctium (1-1-8-ium) was the placeholder name for Oganesson , the 118th element. It did not officially gain its permanent name until late 2016, 5 years after this comic was released. Oganesson is the heaviest element that has been created, as well as the one with the shortest life before it decays into other elements. Xenon is a noble gas with few practical applications, but it is sometimes used in "neon" signs.
