Insights

Released in 1999 and retired long ago, Electro (set 8507) is a Technic Slizer with early constraction ties and unique printed disc elements that draw Bionicle-era nostalgia, and sealed examples are relatively scarce while trading in a thinner, more volatile niche market.

Set Facts

The set comes with extra instruction pages to combine the set with 8504 Judge/Jet Slizer, the 8505 Jungle/Amazon Slizer and 8506 Rock/Granite Slizer to create Ultrarex.
Slizers were known as Throw Bots in the United States.
ENERGY SLIZER'S MISSION To search for neutrons used in the neutralisation of the proton monsters and to increase his energy levels.

Technicopedia

“Each model was a different color and the color matched a themed name and personality. Many models also had a unique printed robotic "face". Articulation of the limbs was accomplished with large ball joints held in position with friction. The single mechanical function in... More each set tended to be a geared articulation point in the middle of the body.”
