"Hmm."
From the moment he entered to the moment he died, it had been around four seconds. It was a bit of a shocker for Rael, since he had made sure Megatron was at least twice as strong as Gaia.
And a Gaia at double her usual power could most likely cleave through several realities with a single slash. That was just how powerful she was.
So once again, it seemed like Rael had to do something a little different. Since the constructs were slightly different from humans, he went ahead and turned back time by a few minutes near the area where Megatron was last.
Then, when Megatron's body reappeared, Rael went ahead and connected the two timelines together. Coincidentally, Megatron remained, and the only thing about him that changed was that he had died on the outside now.
And since his body was still somewhat visible to the current Rael, he went ahead and did a quick revival.
