TFA: Deals With Our Devils, Chapter 5: Lugnut's P.O.V.
By the time autobot and decepticon turned there heads to the source of the mighty sonic, "BOOM", they saw Optimus, but no megatron.

Megatron was thrown back a quarter mile through the cityscape, apparently smashed through several buildings in the process, leaving only holes in the structures shaped as megatron with spider web cracks in the wake of devastation. Optimus lowered his fist causing silence.
