Of course, while Bumblebee does a lot of serious action in the films, tumbling and punching and kicking, you don’t see McFly doing a whole lot of that in the Back to the Future films. In fact, McFly doesn’t get up to too much more hard-core physical action, aside from some skateboarding and wailing on the guitar. Nevertheless, Fox does have a distinctly bowlegged gait, and you can see some of that in Bumblebee, and you can maybe see some Fox mannerisms in his more casual interactions with Sam Witwicky.
Optimus Prime was blasted into pieces by Dragon Megatron. Beast Wars Metals #5 Fortunately, his spark remained perfectly intact—in the remains of his Matrix-shaped spark chamber. Megatron was going to destroy Prime's spark, but Cheetor (now in his Transmetal body) saved it. Prime's spark was eventually swallowed by Optimus Primal, who was upgraded into Optimal Optimus by doing so.
If Optimus ordered his troops to come to the humans’ aid, they found themselves taking part in a struggle in futility, as the entire town was near-weightless, meaning they couldn’t put the humans anywhere where they wouldn’t float away once more. Then, the Autobots heard Decepticons approaching. Helpless in their current position, the Autobots were quickly eradicated by the Decepticons.
