The other members of the Constructor Squad keep an eye on Knockout. Not because he's a treacherous backstabber (he's as loyal as the rest of the squad). Not because his enthusiasm gets him in over his head (it actually helps motivate his teammates). Not because he's a lazy slacker (he works as hard as any of them).
It's because he faints when he gets too excited.
So his teammates watch him, because the last thing you need in combat is an unconscious backhoe.
- Constructor Squad (Micromaster Combiner Squad, 1990)
- Knockout transforms into a backhoe truck trailer which is intended to be the rear half of a purple backhoe truck, which he forms with his combiner partner Grit. He can, of course, be connected to any other Micromaster Combiner or Combiner Transport to make a new vehicle.
- Knockout was only available in a six-pack with his squad mates Grit, Excavator, Hammer, Sledge and Stonecruncher.
- His mold was also used to make the Autobot Gusher.
