What most fail to realize is that many of the characters names are befitting and may or may not be specially chosen based on the names meaning, some could be coincidence so please keep that in mind.
Ethaniel-Combined form of Ethan and Nethaniel. Originated from Hebrew/Latin/Engish. Means Firm/Strong, could be a referance to him being a alien warrior which is physically stronger than a human or perhaps his strong willpower.
Laura-Is of Latin origin and means Laurel Crowned/Wreath/Of an Evergreen tree. Her name could also mean fame/spirit/honor.
Laura is famous because she is well known by the badguys and even the police. She has spirit because she has a strong will to fight for what is right and she is loyal. The thing about the tree/wreath could refer to beauty which is in itself self explanitory but it could refer to her driving a green Intrepid. *shrugs*
Albert-Is an English name and means Noble/Bright. Albert Dent is literally 'a' noble person because he is second in command to the 'king' Banning. Albert is a combination of the names Al and Bert. Al is of Irish/Scottish/Gaelic and means 'handsome'. Well, Dent is obviously handsome [actor anyway]. Just go to IMDb message boards under 'Gordon Currie' and there you will see that he draws in fans from all agre groups and I do mean ALL. Anyway, Bert means Bright/Noble.
Banning-Banning is of Gaelic origin and means 'Blonde child' but could be taken in a more literal sense as meaning "To Prohibit/Ban". Prohibiting Dent from having freewill maybe [I am looking to much into this, I know]. It can also mean "small fair one; son of the fair one".
Nivek-Nivek could be taken from the name Niven which is of Irish/Gaelic origin and means "The servant of the Saints". This could refer to him being used by both Banning and Dent and Ethaniel. it also is a ackwards form of Kevin. Kevin means handsome/beautiful and is Celtic/Gaelic.
Breed-Rise/ To give rise to/ Of a kind or type
Myroc-Could be from name Myron which is Greek and means "From Myrrh, a aromatic oil. This would coincide with the fact that Myroc has expensive tastes. He likes driving fancy cars, eating fancy food, and probably uses fancy cologne. Myroc's name also has Cory in it which means Hollow/hill/ or Helmet.
