The Amazo is a fictional sea vessel featured in the CW Network television series Arrow. It was used a pivotal setting in season two of the show and appeared in flashback scenes to the island Lian Yu. The name is taken from a robot super-villain featured in comic books published by DC Comics called Amazo. The character was created by writer Gardner Fox and artist Mike Sekowsky and first appeared in The Brave and the Bold #30 in July, 1960.
The Amazo was a freighter vessel owned by Professor Anthony Ivo. It was occupied by a team of pirates and moored off the coast of Lian Yu sometime in the early 2010s (five years before the start of the series). In addition to its crew, the Amazo also held several prisoners on board, including a Russian scientist named Anatoly Knyazev.
It was here that Ivo and his crew were able to procure a lost Japanese drug called Mirakuru, which gifted a person with permanently enhanced strength, durability and reflexes, but often at the cost of their sanity. When Slade Wilson suffered a critical injury, Oliver Queen and Shado were forced to administer a dose of Mirakuru to him on the Amazo. The drug saved his life, but also drove him insane.
