Ivan was a member of the group known as The Others. He was one of the several Others occupying the decoy camp when Michael was captured. Later, he would help bring Ben to the Pala Ferry Dock when he met with the Others' new captors and would help Michael launch the boat to leave the island. After the capture of Jack, Kate, and Sawyer, they were placed in separate holding quarters. When Sawyer attempted to make his escape, he aided in capturing Sawyer along with Tom, and also helped bring Karl who was also escaping back to the camp.
Ivan joined Colleen and Tom in taking The Galaga out in the attempt to steal "The Elizabeth" from Sayid, Jin and Sun. After Sun had shot Colleen, he overheard this and fired several shots at Sun. It was Tom that would later fire shots at Sun that sent her overboard. Along with Tom and the rest of his team, they successfully escaped with the boat.
Ivan was also present for Ben's surgery, and questioned as to why his blood pressure was dropping and if he should be bleeding the way he was. Upon hearing this, Jack struck Ivan in the face, and created a hostage situation as he cut Ben's kidney sack to barter for Kate and Sawyer's freedom.
When Ivan regained consciousness, he was ordered by Juliet to go help Danny and Jason find Kate and Sawyer. He returned to the cages and freed them and the three pursued Kate and Sawyer through the jungle. Jason was struck in the head by Alex's sling, and Kate and Sawyer hid in a foxhole to avoid being seen. Pickett later recieved a radio call from Aldo saying that Alex, Kate and Sawyer were at a Hydra facility where Karl was being held, the three arrived only to find Aldo unconscious and Kate, Sawyer, Alex and Karl were gone. Juliet arrived to tell Danny that Ben gave the order to let them go free, however, Danny refused this saying that he knew Ben would rather let them die than go free. Ivan was later administering an injection to Ben's infected stitching on his back, when Jack entered the room and demanded that he stop.
Ivan was later a part of the team headed by Ryan Pryce that attempted to extract the pregnant women from the 815 survivors' camp, unaware that it was a trap. He was killed when Bernard shot a pile of dynamite near one of the tents, detonating it.
