Compound 13

Compound 13, also identified as Compound Thirteen, is a fictional chemical agent featured in comic books published by Marvel Comics. It first appeared in Captain Marvel, Volume 1 #34 in September, 1974.

Compound 13 has been described as "the ultimate achievement of biological research -- the final nerve gas -- instant death". A single canister filled with the compound could destroy every living thing in an entire state. Sufficient volumes of it could depopulate the planet within a day.

Compound 13 was developed by the United States military as part of a top secret project being conducting at a United States Air Force base in Gary, Indiana. The military sent Carol Danvers to the base to oversee transport of a canister of Compound 13.

Just as the canister was being loaded into an armored truck, the super-powered villain known as Nitro made his debut appearance. He stole the compound on behalf of his secret bosses, the Lunatic Legion. Captain Mar-Vell arrived at the military base, and Carol Danvers expressed to him the dangers of Compound 13. He then flew off to confront Nitro. Nitro used his power of self-detonation to cause an explosion that ruptured the canister. Mar-Vell quickly re-sealed it, but he was exposed to the nerve agent. Although his Kree biology was able to prolong the effects, the exposure to Compound 13 would ultimately give him cancer, resulting in Mar-Vell's death.
