Said to be imbued with the Spartans' strength and defiance, but was destroyed in a museum explosion in 2005. At least one shard of shrapnel survived and retained its abilities.
The wearer gains the superhuman strength and determination of the Spartan army, manifested as armor covering the body. However, anyone who comes into skin contact with the wearer develops a rust-like infection that slowly corrodes the body.
The rust infection only affects those the user is angry at; Cody infected people who he was boxing with and were part of the plant closure. Cody was able to save his father and did not infect him which Artie explained was because of the boy's love for his father negating the artifact's downside.
The shard could not be retrieved, as it was lodged near the heart of a survivor of the museum explosion. However, the piece was neutralized by Myka by introducing neutralizer goo into the survivor's bloodstream.

ARMOR OF THE 300 SPARTANS
The Battle of Thermopylae was fought between an alliance of Greek city-states, led by King Leonidas of Sparta, and the Persian Empre of Xerxes I over the course of three days, during the 2nd Persian Invasion of Greece in 480 BC. Xerxes had amassed a huge army and navy, and set out to conquer all of Greece.
The Athenian general Themistocles had proposed to block the Persian army at the pass of Thermopylae, and simultaneously block the Persian navy at the Straits of Artemisium. A Greek force of approximately 7,000 marched north to block the pass. The Persian army, was alleged to have numbered between 100,000 and 300,000. Vastly outnumbered, the Greeks held off the Persians for 7 days by..."
"pass. After days of battle, a local resident named Ephialtes betrayed the Greeks by revealing a small path that led behind their lines. Outflanked, Leonidas dismissed the bulk of the Greek army, and remained to guard the rear with 300 Spartans, 700 Thespians, 400 Thebans, and a few hundred others, the vast majority of whom were killed. The following year, however, a Greek army decisively defeated the Persians at the Battle of Plataea, thereby ending the Persian invasion.
The Battle of Thermopylae is an example of the power of defending native soil. The performance of the Spartans at the Battle of Thermopylae demonstrated the advantages of training, equipment, and good use of terrain as force multipliers and has become a symbol of courage against overwhelming odds. The armor of the 300 is believed to have been imbued with their strength and defiance."
