Stonecruncher is the frat boy of the Constructor Squad. He's loud and enthusiastic about all their missions, and always ready to bellow out, "Constructor Squad rules!" Unlike many Decepticons, he displays fierce loyalty and protectiveness toward his squadmates, especially his quiet combiner partner, Excavator.
- Constructor Squad (Micromaster Combiner Squad, 1990)
- Stonecruncher transforms into a crane truck which is intended to be the front half of a yellow bigger crane truck, which he forms with his combiner partner Excavator. He can, of course, be connected to any other Micromaster Combiner.
- Stonecruncher was only available in a six-pack with his squad mates Excavator, Grit, Hammer, Knockout and Sledge.
- This mold was also used to make the Autobot Retro.
- In Dreamwave's More Than Meets The Eye encyclopedia, Stonecruncher is depicted flipped left-to-right. (His combiner pin is on the wrong side.)
