AVENGERS #16 (Alternate Cover) (Oct 1999) Marvel Comics AVENGERS #18 (Sep 1999) Marvel Comics

Polemachus is the extradimensional homeworld of the Avengers' sometime foe Arkon; it's essentially a sword-and-sorcery world but with some weirdly advanced technology. From time to time, the energy rings surrounding Polemachus weaken, boding ill for the world. Arkon has at times sought to bring about nuclear conflagrations on Earth, which would restore the rings of Polemachus, but has always been thwarted and given an alternate solution. At one point, he warred witht he alternate future women of Femizonia, but that conflict, which drew int he West Coast Avengers and the Fantastic Four, ended when Arkon and the Femizonian leader Thundra became smitten with one another. She went on to become his wife in Polemachus. Polemachus and Arkon were last seen in Avengers v.3 #17-8, during Jerry Ordway's fill-in run. Polemachus and Arkon first appeared in Avengers v.1 #74.

Krona is a renegade Guardian of the Universe, whose crime was attempting to view the beginning of the universe, an act which had dire consequences, unleashing entropy into the universe far too early. In addition, the action created the Pre-Crisis multiverse, including the anti-matter universe of Qward, and granted power to the Anti-Monitor who would later precipitate the Crisis on Infinite Earths. Banished from Oa for these crimes, Krona managed to return on two occasions in his efforts for revenge, but was defeated each time by various Green Lanterns, including Hal Jordan and Alan Scott. Still later, Krona became a manifestation of entropy itself and battled the Green Lantern Corps, the Darkstars, and the Guardians, finally being apparently destroyed by a black hole in Darkstars #24. He first appeared in Green Lantern (Silver Age series) #40. Read more about Krona.
