Thoughts on Superman #654

Sperman #654 “On Our Special Day”
Kurt Busiek, writer
Carlos Pacheco, penciler

Busiek almost pulls it off. He almost makes me believe that Superman can identify the presence of a villain across town just by hearing his particular heartbeat.

scene from Superman #654

I’m not convinced that every person has a unique heartbeat, but I am willing to accept that Superman with his super-hearing (especially the new powered-up Superman) would be able to hear all the subtle nuances of each heart beat — the valves opening and closing and the blood rushing in and out — as good as, if not better than, the best medical equipment available. With his abilities, I can accept that he would be able to tell people apart by their differing heartbeats, but I still don’t think he would be able to hear a particular heartbeat and know instantly whose it was.

Heartbeats change. They’re not like fingerprints. You’re born with fingerprints and they stay the same until the day you die. That’s very different than your heartbeat.

First, the heart rate and rhythm are greatly affected by daily living. Stressed or relaxed? That will affect your heart rate. Have that double shot of espresso or a chocolate bar this morning? That will affect your heart rate. Dehydrated? That will affect your heart rate. Exercising? That will affect your heart rate (at least it will if you do it right). Take your blood pressure medicine? That will affect your heart rate, though less and less throughout the day as the medicine wears off.

The sound of the heartbeat changes as well. The valves can stiffen or loosen with age or various medical conditions, changing the beat. Age or disease can also screw up the synchronization of the valves. Heart attacks will change the heartbeat. Hydration status and fluid status will change the sounds.

These are just a few of the hundreds of variables that can affect heart rate, rhythm, or beat. So even if there were such a thing as an individual’s unique heartbeat, the fact that it can change from moment to moment would render this information useless.

That being said, I’m willing to accept that Superman’s ability to distinguish people by heartbeat alone is canon as I’ve seen it mentioned in at least two different comics, but just don’t expect me to like it.

  1. But. but… He’s *Superman*!

    (I can’t even bring myself to say “He’s the goddamn Superman!”, that’s just how gosh darn swell he is…)

    Seriously. He hears a shot over a cell phone, flies halfway around the planet, and stops the bullet. He can hear freakin’ cells dividing inside Manheim’s aging ventricle, and assess how long until failure.

    All those sparrows…

  2. I’d argue it’s more reasonable than you grant. Think of a person’s voice. It changes with age. It can be affected by injury. It will sound different if a person is stressed, versus relaxed. Some medications will indirectly affect the inflections by affecting emotional state. The volume of someone’s voice can vary, from a shout to a whisper. Yet it wouldn’t be unreasonable to have Superman recognize someone by their voice. Think of “rate” as a property akin “volume” - people’s voices are recognizable even over a wide rate of volume, though there’s a tail-off at the ends of a scale (someone screaming is less distinguishable than normal volume).

    Note also the feat isn’t like he heard it once when the subject was a small child, and now recognizes an old man with multiple heart attacks. He seems to be comparing some general features “It’s a [voice]. Deep, slow, mild [accent]. It’s “Ugly”, Mannheim’s [voice]”.

    So if he’s listening for a particular sound-pattern which hasn’t changed too much *on the average* from when he last heard it, it’s a logical extension of super-hearing, being able to hone in on other “body-voices”.

  3. Here’s how I think it works: Kryptonians have psychic powers. They were bred for it during all that genetic engineering they did, post-Clone-Wars (is that still in continuity?). The heat vision, as Salaak pointed out in an Action Comics shortly after the Byrneboot, is “telekinetic agitation of molecules”, ie pyrokinesis. The flight and strength are TK as well. The invulnerability is a telekinetic forcefield, which was pretty much Byrne’s explanation for his suit never ripping. The vision powers and the hearing are just clairvoyance, constrained by the subconscious to mimic ordinary-but-enhanced vision and hearing. So when he says he’s hearing a particular heartbeat he believes he is, but really he’s picking up on something else, something requiring psychic ability, like a sort of a human RFID tag that everyone (presumably) has. Supes is in denial about his abilities, mainly because they’re gengineered to work just so. If ever he or another Kryptonian managed to work through the mental blocks, there’d be very little they couldn’t do. Solar powered Dark-Phoenix-class genetic mutant? Check!

    Mind you, I quit reading Superman right about the time of that stuff about Zod and/or the priest with cancer. I realised that whoever was writing it had all the literary talent of earwax, and I decided to spend my money on something better, like cigarettes or crack cocaine or somesuch — something I wouldn’t regret.

  4. So even if there were such a thing as an individual’s unique heartbeat, the fact that it can change from moment to moment would render this information useless.

    Not even getting into the Superman aspect, the human voice also changes from moment to moment depending on conditions, and we are able to recognize individual voices. You live with someone long enough you even recognize the sound of their breathing.

    So it seems possible that someone who can hear heartbeats could learn to recognize them.

  5. It’s surprising that although Superman could detect other supposedly distinctive features of Mannheim’s heartbeat, he didn’t notice that it was an awful lot bigger and louder than it should have been.

  6. The real problem here is not the feasibility of this “power,” but the fact that the writers have taken the next steps in the rapidly accelerating process of writing themselves into a corner. As Superman approaches omniscience and omnipotence (and let’s face it, this is getting close to that point — the bullet scene described by another poster violates several laws of physics), it becomes exponentially more difficult to create credible challenges to his ever-escalating abilities. Yes, Grant Morrison makes it work, but who else will be able to pull it off when he moves on? Moreover, Superman’s omnipotence renders most other characters in the DC Universe moot. What function does the Justice League serve when omnipotent Superman is available? Applause? There were sound dramatic reasons for the reboot, and I’m sorry to see those abandoned. I started regularly reading Superman with the reboot, and dropped the books as the reboot began to be unraveled.

  7. AT LONG LAST - I have been WAITING to write this….

    All this Superduperman god like powers is why this humble aging comics geek…

    “Really likes Batman Better” !!!!!!

  8. Bryan,

    Of course, before they decided to add his fear of fire, Martian Manhunter actually overshadowed Superman in many ways. He was just as strong, just as fast, could fly, and also got nifty telepathic and insubstantiality powers.
