- "What is that?"
"That's palladium, 0.15 grams. We need at least 1.6, so why don't you go break down the other 11?" - ―Ho Yinsen and Tony Stark[src]
Palladium (Symbol: Pd), is an element originally used by Howard Stark on the Arc Reactor powering the Stark Industries Headquarters. Tony Stark also used it originally for his miniaturized arc reactor, but when it began to poison and slowly kill him, he replaced it with a new element he managed to synthesize using his father's old notes.
History[]
Howard Stark's Design[]
- "What, is he constructing a palladium core? The man's a certifiable genius."
- ―Whitney Frost[src]
By 1947, Howard Stark was planning to build a palladium core and had the blueprints on a table in his home in Los Angeles; Whitney Frost, a genius scientist herself, saw the plans and thought of how ingenious Stark was.[1]
Poisoning Tony Stark[]
The effects of palladium poisoning on Tony Stark
Tony Stark used palladium as the core for his Arc Reactor,[2] but it was increasing his blood toxicity. After searching for every known element, he still could not find one that would not get destroyed, so he had to remain with the palladium.
Natasha Romanoff, aware of this problem, informed Nick Fury of his condition. When the three of them met at Randy's Donuts, Romanoff injected Stark with lithium dioxide to slow his poisoning. Fury provided Stark with some of his father's old things. He discovered an element that could fulfill his needs through a hidden message. He proceeded to re-create this new element using the molecular structure provided by his father and created another arc reactor that cured his palladium poisoning. Stark continued to use that reactor and found that it was more powerful than the original arc reactor that relied on palladium.[3]
Stolen from Jeri Hogarth[]
Jeri Hogarth purchased palladium hardware, only for it to be stolen and pawned by Inez Green and Shane Ryback.[4]
Alternate Universes[]
Scavenged from Weapons[]
- "Palladium. This is what we're looking for. I need eleven of these."
"Eleven? For what purpose?"
"Just help me gather them." - ―Tony Stark and Ho Yinsen[src]
Stark Industries used palladium to power their weapons. Tony Stark was kidnapped by the Ten Rings, who tried to force him to rebuild the Jericho missile. Under the guise of doing so, Stark requested a series of weapons that contained palladium and removed eleven strips of palladium from them along with Ho Yinsen. Stark remained cryptic about the purpose of the palladium and had Yinsen melt it down. Yinsen then poured the palladium into a mold, where it solidified into a ring. Stark used the ring of palladium to build a miniaturized ARK Reactor to keep shrapnel from a Stark Industries Fragmentation Shell out of his heart.[5]
Assassination of Tony Stark[]
In an alternate universe, Tony Stark used palladium as the core for his Arc Reactor. However, it started to poison him and would eventually kill him. Nick Fury told Natasha Romanoff to inject him with Lithium Dioxide to abate the symptoms of the poisoning. However, Hank Pym infiltrated the vial and entered Stark's body instead, killing Stark and framing Romanoff.[6]
