Onyx

Released in 1999 as part of the Slizer line—marketed as Throwbots in North America—the Onyx set represents an early, experimental era for the Technic theme. These figures were designed to bridge the gap between traditional construction sets and action figures, utilizing a core ball-and-socket joint system that allowed for dynamic articulation. The series was created to compete in the burgeoning market for buildable characters, reflecting a shift toward modular play that would eventually evolve into the Bionicle phenomenon.

The Onyx figure is defined by its dark, industrial color scheme and a unique 'thrower' arm mechanism that could launch a spinning disc. The design prioritizes a gritty, robotic aesthetic that distinguished it from the colorful sets more common in late 90s building toys. While the Slizer line was short-lived, it is historically significant for introducing the specific building techniques and character-driven storytelling that became the backbone of future construction themes.
