Batman is sometimes seen to wear lead lining in his costume, for example in Superman/Batman Annual 1 or Superman/Batman #9, as well as other occasions as detailed here. Lead Batsuit 1 Lead Batsuit 2

In DC canon, lead poisoning exists, is dangerous to people, and can be fatal in certain extreme forms, for example in Daxamites like Lar Gand.

The times when Batman has worn lead lining in his batsuit, so as to prevent Kryptonians from seeing through it, keeping kryptonite in it, etc; would he get lead poisoning? The batsuit is primarily kevlar, ceramic plates, etc; any lead would be inside some other material.

I know he is willing to use lead for these purposes elsewhere, for example in the batcave in Earth-0 and when he hid out in the lead mines in the Injustice universe? Has this issue come up in the comics, and if so, does he ever address possible lead poisoning?

  • a few problems, I'm pretty sure lead has to be ingested regularly for someone to succumb to lead poisoning, two wouldn't Kryptonians be wary of the fact that he's hiding something if he's taken the time to line it with lead? and finally I believe he could it would just become very heavy. Wouldn't it just make more sense for him to have a lead pouch on his belt with a piece of kryptonite in it?

    As currently phrased, this sounds like a real world science question, which would make it off-topic here. Might be better to ask if Batman actually has worn a lead-lined suit, as that would make it a question about comicbook facts, rather than real world facts. Commented Dec 1, 2021 at 16:04
  • Sure, but then he wouldn't be able to eat his armour if he got stranded in the mountains. Commented Dec 1, 2021 at 16:24
  • @Villan I think Batman has done the lead case with a piece of kryptonite in it. Just in case he needs to fight Superman.

  • @Ushumgallu It would be good if you could point to specific versions of the batsuit that have lead in them. Note also that Composite Armour is well-described, and there's no reason to expect any skin contact with a layer of lead in a sensibly-designed system.

Lead encapsulation has been a safe and time-tested alternative to mitigate lead hazards

Yes, “lead poisoning” is canon in DC comics. Lead Poisoning

But luckily, numerous safety and hazardous materials organizations have studied the problem of lead exposure and have settled on some widely-considered best practices.

Lead Encapsulation Lead encapsulation refers to covering up or containing a lead exposure hazard, most typically from lead-based paints, but also lead sheeting.

Lead encapsulation methods include:

Sealing the lead hazard by using encapsulating coating;

Attaching adhesive barriers to the surface of exposed lead hazard

Isolating the lead hazard by building a barrier around it.

Given the resources available to Bruce Wayne, one would think he could certainly apply lead encapsulation methods and materials to his bat-suit to protect against the hazard of lead exposure from including lead sheeting within his suit. Some examples might be a bonded surface barrier (I.e. “vulcanized” protective surface on the lead), a protective shroud or pocket within his suit that isolates contact between lead and skin, or painting the lead in the suit with an isolating coating before it’s inserted into the suit.

A risk would be penetration or destruction of the encapsulation, however, it’s more likely that whatever damaged it would be a more immediate hazard than the newly and now temporarily exposed lead. For example, blunt force trauma by someone who could shatter a mountain, explosions, projectiles, falls from tall heights, impalement by sharp weapons or objects, death rays, Omega beams, heat vision, et. al. are all arguably more immediate hazards to the suit’s wearer than limited environmental exposure to lead.

Despite these risks, Batman on occasion has lined his costume with lead:

However, because some superpowered individuals such as metahuman hitman Tommy Monaghan have the power to see through solid objects, Batman also lines the cowl with lead to protect his identity. That property is absent in The New Batman/Superman Adventures crossover "World's Finest", where Superman saw through Batman's cowl with ease.

We can presume, Bruce Wayne has either safely considered how to encapsulate his lead exposure, or has accepted the hazard with the benefits it provides to his line of action.

    Thanks, this was what I was looking for, with real-world science and in-universe examples
