The Collector shares similar traits of most serial killers in horror cinema; intelligent, insane, murderous, destructive, sneaky, cruel, savage, merciless, aggressive, emotionless, and violent. A mentally deranged and brutal man, the Collector scopes out his victims by posing as an exterminator, giving him easy access to his victims as well as allowing him to plan ahead of time on where to place his traps. The Collector then kills his victims by locking them in their own homes and killing them.
