Sometimes even the smallest details of superhero comics could make a big impression, which includes some of the shiny baubles and costume accoutrements the kids might classify as "bling". Or not (I'm sure the term "bling" is now hopelessly outdated). Here's four that stand out (click on the images for larger views):
1. The Legion of Superheroes Flight Ring: You'd think becoming a member of a 30th century club for superpowered teenagers would be cool enough, right? Wrong! In addition to the aforementioned cool factor, each (non-flying) member of the Legion of Superheroes would also receive their very own flight ring (which doubled as a communication device).
2. The Phantom's Skull Ring: Bad guys punched by the Ghost Who Walks would get an added souvenir: the impression of a skull mashed into their faces by the ring on his right hand! Crime not only doesn't pay, but it also leaves one heck of a mark!
3. Warlock's Soul Gem: Created in the hippie-dippy daze of 1967, the man-god known simply as "Him" evolved into a sort of counter-cultural superhero named Adam Warlock in the early 1970's. Very much a product of the Eastern-tinged Psychedelic era, Warlock sported a "soul-jewel" (later known as the Soul Gem) on his forehead, which gave him the power to manipulate matter, devolve organisms to more primitive states, and absorb the souls of other beings into the gem's alternate reality. Throw in a snazzy gold belt and wrist bands (not to mention that fanged skull-thing near his flared collar), and you've got yourself some major metaphysical mojo.
4. The Eye of Agamotto: Speaking of Eastern-tinged psychedelia, one of THE coolest pieces of comic book bling has got to be The Eye of Agamotto, a magical amulet worn by Dr. Strange. At Strange's command, the amulet opens to reveal an eerie glowing eye, which gives Strange the ability to see through illusions and disguises, invoke scenes from the past, track psychic or magical energy, project shields, open dimensional portals, or weaken evil mystical beings. Ah, but that's not all, as they say on the infomercials. The Eye can also be used to probe minds or search other-dimensional realms, in which case the eye leaves the amulet and affixes itself to Dr. Strange's forehead...to maximal creepy/cool effect.
