Found the Megatron Must be Stopped scene over on BitChute. Not quite the entire thing, but it's the bulk of it.

To this day, I've still never seen a "last charge" that even remotely compares to what Optimus Prime did in this scene. Looking forward to the day when the fanbase can recreate the full and uncut scene from the storyboards.
