According to the director of this series Yutaka Izubuchi, Rahxephon is an homage to Brave Raideen, but I also see strong influence of Neon Genesis Evangelion throughout this series. It's almost as though the series is is an amalgamation of the two. Ayato Kamina was a teenager living a normal life in Tokyo. What he didn't know was that he was a descendant of interdimentional race of Mulians, and Tokyo was encapsulated in an energy field which the outsiders called Tokyo Jupiter where time passed at a slower rate than the outside world. Earth is under attack by Dolems - a quasi robot created by the Mulians. Ayato Kamina is lead by his classmate Reika Mishima to an egg containing Rahxephon. Rahxephon only accepts Ayato as its pilot due to his genetic ties with the Mulians. The plot of Rahxephon and its pilot having ties with the Mulians is strait off of Brave Raideen, and also the design of Rahxephon takes from Raideen. The main character who is an introverted in the closet type individual is similar to that of Neon Genesis Evangelion. People in this story seems to use "official assignment" as an excuse to forward their motives and importance within the organization. The story is rather dark with apocalyptic theme running through its plot, and introverted characters that fills the roster doesn't make the story any more uplifting. Artistry is high, and there is an experimental aspect of using music as main ingredient of the story. Bolodin's Polovetsian Dances is played in many sequences. The story progresses slowly, and that takes away from the excitement of action that should be the main focus of super robot anime of this type. Also the characters appearing in this series are mostly unattractive individuals as human beings, and takes away from the plot. The style of the story - a dark apocalyptic sci-fi with introverted main character which was popular in the early 2000s, is somewhat passé by now. Watch this series for its artistry and its somewhat mysterious mood. But don't expect much action in each episodes.
