They all take souls and live in "Hell like dimensions" just like Mephisto..... (Kurios's own son is refered to as The Son of Satan: Daimon Hellstrom... or Hellstorm for short.... how is mephisto more Satan than Marduk Kruios?)
You know the one who said 666 was his number and wanted to annex hell on earth. You know the one who hates God whom cast him from Heaven into Hell..... Last seen swearing at the heavens from hell when Zadkiel won the war in heaven..... something no one on the above list has ever even attempted... including Mephisto....
For all practical purposes Mephisto isnt even the closest "hell lord" to the christian interpretation of the devil. That falls to Lucifer....
