Codex: The Rebellious Robot Princess

Codex, number 73 in the esteemed "100 Heroines" collection, is not your typical princess. Created by Townes Galvin, she's a robot princess from the future, where human enslavement is the norm. This deeply troubles Codex, and she harbors a growing disdain for her father, the King, who seems to find her existence merely a series of reboots. "She's a robot princess in the future, where humans are slaves. She doesn't think they should be," her profile states, underscoring her burgeoning independence.

Her journey to becoming a teenager is a lengthy one, filled with countless reboots, but once she finally achieves this milestone, she gains access to a time machine – a birthday gift that sets her on a path of defiance and adventure. Her initial foray into the past lands her in 2019, where she becomes infested by a mysterious 'Mother Codemite.'

Codemites are described as dangerous nano-mechanical organisms born from celestial events. They possess the ability to bond with and control robots, much like a hive mind ruled by their queen. This unique affliction, however, doesn't break Codex; instead, it leads to an agreement between her and the Mother Codemite. She leverages this alliance to protect humans in 2019, armed with an EMP baton capable of disabling pesky robo-elephants.

Beyond her technological armaments, Codex possesses ferrokinesis, a fascinating ability to manipulate metal with her mind, seemingly powered by her 'princess crest.' Despite her formidable powers and metallic stealth chassis, Codex grapples with the typical angst of a teenager, amplified by her robotic nature and her father's persistent interference. Her personality is marked by sarcasm and rebellion, as she quips, "Nice gift. You're not getting one of those," a sentiment that perfectly encapsulates her independent spirit. She isn't just a machine; she's a complex entity navigating destiny, power, and the eternal struggle against parental control.
