Sergei

During his brief encounter with Wesker on the Umbrella Caucasus Research Facility, Sergei injected himself with an advanced strain of the T-virus, converting him into a Tyrant with exposed skull and his arms fused into one large tentacle. He was able to retain his memories and speech ability.



Wesker theorised that the mutation Sergei underwent was unfluenced by the host's mindset. Sergei mutated into a monster that, according to him, is the picture of his true personality: a man who suffered in the inside.
