Mobile Suit Zeta Gundam

Z Gundam is an excellent Gundam series, and considered among fans to be the best and most serious. Unlike Gundam Wing or G Gundam (which debuted on Cartoon Network) this one takes place in the same "universe" as the original Gundam (which was also on Cartoon Network for a time). It is 8 years after the war against Zeon, but during this time, the Earth Federation has become corrupt. In fear of other Zeon-like uprisings, they create a police force known as the Titans. However, the Titans are mere bullies, and the law doesn't apply to them (think the Nazi SS during WWII). A rebel faction, the Anti-Earth Union Group(AEUG) are the good guys in this series.

Among the AEUG is ace pilot Quatro Bagina, (who is really a disguised Char Aznable, villain from the original Gundam), and 17-year old Camille Vidan, who is the main character of this series. Camille is a powerful Newtype, and what happens to him and his family in the first few episodes will prove to you how dark this show is. Even Amuro Ray returns and plays a big role in Z Gundam. The best part? ZZ Gundam, which has a whole new set of characters and takes place one day after Z Gundam ends, begins.
