Cthulhu is a malevolent entity who hibernates somewhere beneath the ocean in the South Pacific. The imprisoned Cthulhu is the source of constant anxiety for mankind at a subconscious level, and also the subject of worship by a number of human religions.
The Kraken (/ˈkreɪkən/ or /ˈkrɑːkən/) is a legendary sea monster of large proportions that is said to dwell off the coasts of Norway and Greenland. The legend may have originated from sightings of giant squid that are estimated to grow to in length 12-15 meters(40-50 feet) including the tentacles. The sheer size and fearsome appearance attributed to the kraken have made it a common ocean-dwelling monster in various fictional works.
