Zentrix is a CGI donghuanote which began airing in Hong Kong in 2003. The basic premise was that a princess had to go back in time to prevent an evil AI from taking over the world, with the help of her trusted robot. Produced by IMAGI, the Hong Kong-based company responsible for the Astro Boy and TMNT CGI films. The human characters weren't all too well animated; however, the robots were very well animated.
- Aerith and Bob: Emperor Jarad has a daughter named... Megan.
- All Your Base Are Belong to Us: Doctor Coy's lab is invaded and destroyed near the end of the series.
- Bad Boss: Omicronpsy. He has no qualms about destroying servants that fail him.
- Big Bad: Omicronpsy, who wants to take over Zentrix City and rule its inhabitants.
- Bittersweet Ending: Omnicronpsy is defeated, but goes back in time along with the Zeus.
- Dark Chick: Silver General, who is pink and noticeably has more of a female based appearance than the other robots.
- Evil Laugh: Omicronpsy is very fond of these.
- Fountain of Youth: A time machine malfunction makes Megan not only go back in time seven years, but makes her seven years younger too. When she wakes up after travelling to the past, she has an eight years old body, despite still having a fifteen years old mind.
- Imperial Stormtrooper Marksmanship Academy: Omicronpsy's mooks, particularly when they're invading Doctor Coy's lab. The dark and silver series robots do sometimes avert this before inevitably getting blown up.
- Lonely Rich Kid: Megan, before her father gave her Mango as a gift. Until then, her only playmates were robots.
- Missing Mom: Megan's mother died when she was still a child.
- Obviously Evil: Omicronpsy.
- Red-Headed Hero: (Or heroine) Princess Megan
- Secret Test of Character: When Zeus and Quantum are being tested for the mission of protecting Megan, they have to fight each other, and they are equal in power. What makes Emperor Jarad choose Zeus for the mission was the fact that, when confronted with a situation in which they had to protect a human life, Zeus stopped focusing on Quantum to do it, while Quantum kept focused on defeating Zeus.
- Significant Green-Eyed Redhead: Megan. She's the main character, after all.
- Transforming Mecha: Silver 02 can turn into a plane! Doesn't stop her getting destroyed pretty quickly.
- Your Princess Is in Another Castle!: Princess Megan successfully shuts down all the zentriums powering Omicronpsy, only to find he has made a new body that can work independently of them.
