If you liked the Ergo Proxy anime, the Anime-Planet community thinks you'd like:
In the year 2977, humanity has long passed its peak; machines are able to perform any task a human can, and people have succumbed to apathy. However, there remains one who refuses to accept such an existence: Captan Harlock, a pirate who sails the sea of stars aboard his ship, the Arcadia. He is feared and loathed by most inhabitants of Earth, and yet he is their only hope against the Mazones, a strange alien race of beautiful women that threatens humanity. Thus begins a lonely battle in which Harlock and the crew of Arcadia struggle to stay true to their ideals, while slowly unravelling the sad tale of the Mazones.
In a post-apocalyptic world overrun with great beasts called Filth Monsters, a glimmering dome protrudes from the wasteland. This is Zuellni, a mobile city unique for having a consciousness in the form of ‘electronic fairies’. Moreover, Zuellni is an academy where the next generation of powerful Heavens-Blade wielders gather to pit their strength against each other in inter-platoon competitions. Nina Antalk, military student and leader of the 17th Platoon, is intent on recruiting only the best; thus, when mysterious Layfon Alseif transfers to the academy, she instantly recognizes his abilities and decides he’s the perfect candidate to join her group. However, with a secret past that won’t leave him alone, and unknown powers beyond the academy taking an interest in Zuellni, Layfon joining the team is only the start of all their troubles.
Both Ergo Proxy and Chrome-Shelled Regios share alot in common I think. they are both dystopian universes where humanity lives inside of large, bubbled cities. The difference in each lie in the setting. Ergo is dark, and mature, and Chrome is a little more light-hearted. If you liked one, I'm sure you'll like the other.
In times of olde, humans live in constant fear of demons known as yoma. These vicious creatures can take the appearance and memories of humans they have devoured, thus blending into society as they freely feast on human flesh. The key to stopping the yoma lies with the tolerated yet feared Claymores - women who are half-demon, half-human, and fully fated to become the demons that they hunt. Meanwhile, in a village, the young Raki has been banished; his only crime was losing his family to the yoma. Raki is drawn to a Claymore named Clare, and together their journey begins. While Clare fights the yoma plaguing the land, can Raki help her in her struggle to retain her humanity?
Both shows are set in a similar world and have similar themes through the story. White they each presents their own ideas and conclusions. In the end, they are about survival. If you enjoy one show you will enjoy the other one, however, DT Eightron is from 1998 and Ergo Proxy from 2006, so don't expect the same quality of animation and I would't be surprised if Ergo Proxy was inspierd by DT Eightron at all.
In the future, androids live side by side with humans – but not as their equals, as their slaves. Though they look identical, these androids must display a holographic ring over their heads so the difference is clear. One day, a boy named Rikuo finds abnormal activity patterns in the logs of his own android, and alongside his friend Masaki, he sets forth to find where the android has been. Much to their surprise, the duo discovers a secret café known as Eve no Jikan with a single rule: within its walls, there must be no discrimination between humans and robots. In this place, androids appear to be human and are even displaying signs of independence – a trait that should not be possible. Rikou finds his perceptions increasingly challenged as he struggles to come to terms with his own android, and the relationship between man and machines...
