"Grindor's mortal enemy is Jazz. Jazz and Grindor had a battle on Cybertron, in which Jazz almost killed Grindor by cutting him in half with his own blade. However, Starscream saved Grindor by repairing him just before his spark faded. **Tough luck for poor Jazz though, he died the same way exactly 278 years later. " Got that straight from the wiki. Anyone surprised at this considering the massive size difference? I was never really sure how skilled jazz was in the bayverse.
