I am also a fan of Anime, depending on what it is, my personal favorite is Robotech, the old series that aired on network TV in the '80s. It was taken off the air mainly because it was too bloody, and was replaced with the hyper-unrealistic G.I. Joe cartoon that we all know and remain indifferent to.
Robotech is the story of the RDF (The Robotech Defense Force), mainly
of Rick Hunter, a pilot of a Veritech fighter, he's not the greatest pilot,
but he does do his best. The story mainly consists of the RDF, the
Zentradi, the Robotech Masters, and the Invid. I'll explain each for you.
The RDF is simply the futuristic army of Earth's Robotech mechs, the technology was first discovered when a giant space ship, which was rebuilt and christened the SDF-1, crashed on a small island, now known as Macross Island. Thanks to the RDF's Dr. Lang, the technology was used to create a defense system unparalleled in the world, but not space. The Zentradi are the first enemies encountered in the series. They are a race of giants, genetically engineered by the Robotech Masters, as a living army of warriors, they have little culture (all of which is combat-related) and the two sexes are separated by tradition. The Robotech Masters are another race introduced later in the show. They created the Zentradi, and pioneered the entire Robotech age. It was the Masters' flagship that crashed upon Earth years ago. The Invid are the greatest threat to all the other races. They are a race of humanoid creatures, filled with hate and jealousy. They attack and destroy any other race that holds 'The Flower of Life' also known as protoculture (which powers the mechs). They have a huge grudge against the Robotech Masters who seduced the Invid Regis for the secret of protoculture.
