The iconic 1980s robot has gotten new life with a Lego Ideas kit that just hit 10k supporters.

‘S-A-I-N-T Prototype Number 5’ or ‘Johnny 5’ rolled his way into the hearts of audiences back in 1986. Initially made as a weapon, a lightning strike changed his programming into a childlike robot with the need to explore and for endless amounts of input. After learning about people and the world around him, Johnny rejects his initial programming and has to create his own path.


Kit creator RJ BrickBuilds shared their inspiration…

In Short Circuit 2, Johnny 5 set up a new business with his old friend Ben Jahrvi that builds and sells toy robots made in Johnny 5’s likeness. This little robot never made it into actual production after the film. Johnny 5’s popularity and the unavailability of access to these cute little Johnny 5 robots made people clamour for this toy. To date anyone can google sites for 3D printing Johnny 5 robots and websites dedicated to producing both life-like and miniature Johnny 5’s. Johnny 5 is one of the iconic fictional robots in cinema to date. He’s part of every child who’s lived through the 80’s like me who are now AFOLs and longed for the Johnny 5 toy that never came out.
