Igor is Vladislaus Dracula's servant. He was earlier employed by doctor Victor Frankenstein as his assistant, but chosed later to betray his employer to the Dark Lord after the creation of Frankenstein's terrible monster. At first Igor fled the doctor's castle when it was attacked by angry villagers, but when he saw the creature carry its creater to the old windmill he shouted out his former boss name in the night, which was heared by the mob.
One year later Igor was still in the service of the Count and his brides, unfaithly loyal and willy to help him achieve his goal. Unfortunately his relationship to Dracula was no less changed from his time with the doctor, when the master used him as a dog to take care of his other servants, one of them to mention was the werewolf. When Van Helsing in company of Anna Valerious and his loyal sidekick and companion, the young Catholic friar Carl succeeded to invade Dracula's castle Igor was the first one to spot them. At first he was to warn his master about the intruder's but Van Helsing nailed him to the wall in order to question him about the Monster. Van Helsing, who at that had been bitten by the werewolf and in a good way to become one himself, threated the greedy assistant to the life which convinced him to led the group to the very room there Count Dracula stored the only known anti-dote to the curse of the werewolf.
However Igor set up a trap for them due to the sudden appearence of one of Dracula's brides, Anna battled her in order to give Carl enough of time to get the anti-dote to Van Helsing.
