Dr. Anthony Ivo is a scientist who will stop at nothing to unearth a breakthrough that dates back to the latter days of World War II.

Season 2
In, Anthony makes his first appearance during the island flashbacks as the employer of the crew of the Amazo. He orders the Captain of the Amazo to release the captured Sara Lance, takes her to his quarters, and then informs her that he is a scientist who intends "to save the human race".

In, he interrogates Oliver Queen (who had adopted the pseudonym "Tommy"),  explaining that he is looking for a sunken submarine containing a serum created by the Japanese Army during World War II, The Miracle. After Sara tricks Oliver into confirming that his friends are alive, Anthony declares that Oliver will take them to Slade and Shado on Lian Yu, then reveals that he knows Oliver's real name.

In, he and his men take Oliver and Sara to Lian Yu. When they cannot find Slade and Shado in their hideout, he orders the Captain of the Amazo to blow it up. He forces Oliver to take him to the grave of the Japanese soldiers that Oliver had stumbled on earlier, then he and his men search for the hōzen, which Oliver had previously taken. When they are unable to find it, Anthony grows angry and demands that Oliver tell him where it is, having the Captain threaten to shoot Oliver's hand off. After Slade and Shado ambush Anthony's group, he agrees to release Oliver.

Later Anthony is seen shooting the wounded Captain in the head for his failure to prevent Oliver's escape, and promoting the first mate of the Amazo to be the new captain.

In Oliver says that Ivo is dead.
