The Titan Trappers are a cult-like group of wild witches who dress up as Titans to seek and kill them. They aim to kill all Titans for the Grand Huntsmen, the Collectors, who they worship and follow and need Titans blood to summon which is another reason they want to kill Titans. The Titan Trappers live on an island where they live in Medieval-like homes with farms and have a castle-like place where their elder/leader, Bill, resides. They also have a teleporter to the Boiling Isles.
