Nadia: The Secret of Blue Water

Nadia: The Secret of Blue Water was released in 1990 and was one of those anime series were the anime was created before the manga. Nadia:The Secret of Blue Water takes place in 1889 in Paris, France during the height of technology and technological discoveries in science. It tells a completely different origin of Mankind and has plenty of Christianity and Biblical references in it. In Nadia:The Secret of Blue Water , Mankind and all life on Earth were created by the Atlanteans of legend a hundred million years ago. The Atlanteans created the very first human the Biblical figure Adam who was a giant.The Atlanteans are extraterrestrials from a star system 77 million light years away. The Atlanteans established Tartessos on Earth and lived there until the Neo Atlanteans betrayed the royal family after the death of the queen Nadia and Neo's mother and Nemo's wife. The Neo Atlanteans possessed the Prince of Tartessos , Neo causing the King of Tartessos , Nemo to destroy Tartessos. The really advanced submarine the Nautilus has super advanced modern day technology (at the time 1990).The Nautilus must remain hidden from the eyes of the rest of Mankind because they can not see such an advanced technology during the time period and must remain unseen from the world because its technology is hundreds of years ahead of its time and it is actually thousands of years old! The supporting character is a 14 year old French boy, inventor, and genius named Jean whose father was lost at sea and who lives with his aunt and uncle. The main character is Nadia. On a Mary Sue scale from 1 to 10 Nadia would get an 8 . She's a princess, her race are extraterrestrial "gods", her family are the "rulers" of Mankind, her race are the creators of Mankind, she's an acrobat, lion tamer, dancer, Jean falls for her at first sight, and she can understand animals. The Grandis Gang consisting of a rich Italian heiress Grandis, the chauffeur of the Grandis family, Sanson (who is named after Samson from the Bible), and Hanson the driver of the Grandis family who is also an inventor, are former bad guys turned good guys that join the good guys and aid and protect them.The Grandis Gang's Grandis and Sanson are sort of a prototype Jesse and James from Pokemon. I don't understand how Grandis became the guardian of Nadia and how Nadia got to even know Grandis and her gang. The anime begins with Nadia running away from Grandis and her gang because Grandis wants Nadia's necklace the "Blue Water" and that Nadia was an orphan that grew up alone and works at the circus to survive but how did Nadia even know Grandis and her gang and why would Grandis go from wanting to suddenly want to steal Nadia's necklace from her if she's Nadia's guardian to not being interested in the necklace at all anymore. The French 5 year old orphan Marie whose family was killed by the Neo Atlanteans due to discovering their secret is saved by Jean, King, and Nadia. Marie joins them becoming apart of the group. The crew of the Nautilus includes Captain Nemo the captain of the ship and the father of Nadia and Neo. Electra is the First Officer, (who she and her family were regular civilians of Tartessos )of the Nautilus who doesn't get along with Grandis due to Grandis being in love with Captain Nemo. Electra goes from trying to murder Captain Nemo with a gun for killing her family and Captain Nemo goes from saying Electra was like a daughter to him to the two of them suddenly changing their minds about one another, to having intercourse and producing offspring with one another during that short period of time. I don't understand the reason why Gargoyle hates Mankind. I saw that in the end it was revealed that he was human all along! At the end of the series which takes place in 1902 Jean and Nadia are married and have a son, King has cubs, Hanson becomes a wealthy successful owner of a car company ,Grandis is single, Electra is a single mother, and Sanson is married to an underage teenage Marie who is pregnant with their first baby. I thought Sanson would have adopted Marie since he's old enough to be her father and they met when she was just 5 years old and at the time the only woman he was flirting with was the nurse from the Nautilus who he was trying to give a rose to.This anime is entertaining but has a lot of plot holes that are never really explained.
