- This monster appears in the artwork of "Infernity Barrier".
- This monster bears inexplicable resemblance to "Dread Dragon".
- The above is odd because "Dread Dragon" cannot be used for this card's Synchro Summon.
- However, their design likenesses might make sense in the guise that Dread Dragon and Infernity Doom Dragon are used by Jack Atlas and Kalin Kessler respectively; these two characters were both were part of The Enforcers, however, this monster's more dilapidated appearance may symbolize the darker and more entropic path that Kalin chose, which led to his time as a Dark Signer.
- This card is Kalin's "Infernity" parallel to his Dark Signer's Dark Synchro Monster "One Hundred-Eyed Dragon".
- There appears to be a portion of its brain revealed in between the various prongs that circulate its head (the small pink matter cluster visible directly above its eyes).
- As revealed in the art of "Infernity Barrier", "Infernity Doom Dragon" actually has a perfectly round ridge of "horns", with the brain placed perfectly in the middle - this may imply that the "horns" of "Infernity Doom Dragon" are, in fact, sections of its skull that are opened up, surrounding the brain.
- This monster somewhat breaks the theme of many "Infernity" monsters taking after classical American Western themes - cowboys, Native Americans and the like, though some also resemble European knights and demons - but still fits in by way of resembling a daemonic, somewhat twisted interpretation of a usual concept (in this case a dragon), much like the other "Infernity" monsters appear to be twisted, demonic versions of Spaghetti Western stereotypes.
