An Ivan is a specially re-engineered derivation of the T-103 Tyrant line designed by Umbrella to serve as a bodyguard of Colonel Sergei Vladimir. One Ivan was used in an attempt to kill Albert Wesker in the Umbrella Research Center where Colonel Vladimir ordered it to punish him for his failure and disobedience. During the fight there was an explosion that distracted the Ivan, allowing Wesker to escape from it. This Ivan was later seen defeating a pack of Cerberuses and carrying an unconscious T-A.L.O.S. away from the mansion with Sergei by its side. In 2003, both of the existing Ivans were ordered by Sergei to kill Wesker due to his intrusion and betrayal in the Caucasus facility. Even with their combined teamwork they stood no match against their rival's superhuman powers and were killed.
Similarly to the original T-103, the Ivans wear a limiter coat with black gloves, complete with boots. The color schemes differ, however: the Ivans' coats are white and their boots are white with black shoelaces, while the T-103's are green. They also wear wrap-around sunglasses that include a head-mount display.
Their basic combat functionality is that of a T-103, but had been modified to better assimilate into human society. Major improvements with this model include greater powers of comprehension and the ability to actually pass as a human. However, it is still a model T-103 derivative and, as such, it can presumably transform into its Super Tyrant or R form when its Limiter Coat is destroyed. Neither Ivan deployed ever displayed this ability, however. It should be noted that neither of them had their Limiter Coats substantially damaged prior to their destruction.
