MOTU itself is not related to the Bible...but there is similiar relations/mythology of the ideas for Tytus and other Giants.Same as/similiar to Greek mythology...but the Bible is pretty clear (Read Genesis 6) that Giants once roamed the earth. Tytus is pre-eternia (a time of Giants apparently in MOTU story line) so in a sense, they are similiar stories/ideas (originally from the book of Genesis)
Tytus would be an offspring hybrid,Nephilim (in hebrew means "fallen ones") another meaning is Gigantes (Giants). Tytus would be a prodigy of a demi-god (coming from a fallen angel and a woman)...same goes for Hercules and Atlas etc....when you study into this..you'll find that not all ideas are just created out of thin air and they have an origin.
