In Semitic mythology a number of monsters exist they are as follows:
Elioud: Children of the Nephilim they are part angel though the percentage varies.
Golem: The Golem is a creature formed from clay by Kabbalistic magicians it is commanded to life by incantations and on its head is written the Hebrew word “Emeth” meaning “Live” when the Golem is no longer useful the letter “E” is removed so that it spells “Meth” meaning “Death” and causing the golem to become inanimate. A golem is a slave being taking orders from written scrolls placed in its mouth they are usually guardians and can get out of control if left to live long enough to begin developing freewill and sentience of their own. A famous example is the supposed golem of Prague. To create a golem is a sign of true holiness as it mimics the creation of Adam by God from Adamah clay.
Lotan: A great sea serpent or monster and servant of the ocean God Yam he was slain by Ba’al in early Canaanite combat mythologies. Lotan was probably the inspiration for Leviathan and other sea serpents and is likely a Semitic version of the Sumerian Tiamat.
Nephilim: The “men of renown” and “mighty men of old” often taken to mean giants, the Nephilim were the offspring of the fallen angels and daughters of man. In Genesis this union causes the flood of the world when God attempts to purge the abominations from the world. The word “Nephilim” actually means “those who were cast down” and refers to fallen angels.
Rahab: An angel of the deep described as a great dragon or sea monster it likely influence Leviathan and was itself influenced by the Sumerian Tiamat.
Rephaim: Similar to Nephilim, the Rephaim were giants born of the union of women and fallen angels. In later mythology the Rephaim would be synonymous with the spirits of the dead and were said to dwell in the deep places.
Shalyat: A seven-headed monster which in some accounts is the same as Lotan and is probably influenced by the Sumerian Mus-Sag Seven.
Tannin: A symbol for chaos, a twin-tailed serpent whose name means “howling” or “to coil like smoke”. Tannin is thought to be the same concept as Lotan or Leviathan and probably has a basis in the Sumerian Tiamat. Tannin also describes a species of monsterous whales mentioned in the Bible as being made on the fifth day of Genesis. Interestingly the demons Samael and Lilith are joined psychically and breed through a force called “Tannin-Iver” meaning “Blind Dragon” described as a snake each would straddle earning Lilith the name “Tortuous Serpent” and Samael the name “Slant Serpent” this may also explain why the two demons were replaced with Leviathans in some versions of the Bible.
Zamzummims: A race of giants similar to Nephilim and Rephaim.
