When Nightscream is knocked unconscious, he stays in robot mode. Previously it was established that maintaining robot mode requires constant focus. He should have turned back into beast mode.
Silverbolt scans the fossils of a giant bat and a Tyrannosaurus skull, yet he emerges as a condor. Perhaps the writers were implying that combining these animals together would result in a bird (seeing as the bat is a flying creature, and the T. rex is closely related to birds), but it is still left unexplained. It could be that his DNA-scanner malfunctioned, however that is not hinted at either.
Rattrap immediately recognizes Silverbolt upon seeing him, even though he looks absolutely nothing like he did when Rattrap last saw him.
