Optimus Prime opening the cragaling’s mouth while fighting him does reminds me of when King Kong opens Skull Devil’s mouth while fighting him in “Kong: Skull Island”. Speaking of Kong. Did you know that 8 years before voicing Optimus Prime, Peter Cullen provided the vocal effects of Kong in the 1976 remake of the 1933 film “King Kong” before being replaced by Peter Elliott ten years later in the 1986 sequel “King Kong Lives” which is distributed by De Laurentiis Entertainment Group which also distributes the 1986 g1 movie which is released four months and one week before the release of “King Kong Lives”?

No. Skullcruncher is a Decepticon Headmaster from the planet Nebulos seen in “The Rebirth” A.K.A. Season 4.

How Chrysalis even got these monsters, not sure are they hybrids, or maybe fusions.
 
No way a changeling could simply change/transform into something like this.

Is that supposed to be changeling Skullcruncher??

Now now… don’t gain logic now, Megatron; the war might end if one of you grows up
