Given Unicron's involvement in Transformers: Rise of the Beasts, the G.I. Joe crossover could tie these two stories together by being set after The Last Knight and retconning the timeline.

Videos by ComicBook.com Most fans expected that Unicron, the world-devouring villain behind 1986’s Transformers: The Movie, would serve as the primary antagonist for Rise of the Beasts.

Unicron is the Transformers equivalent to Marvel’s Galactus or DC’s Anti-Monitor: a cosmic force of destruction who serves as a seemingly unstoppable foe for the heroes to overcome.

Dubbed the Bayverse, the live-action Transformers films comprise five Michael Bay films and two prequels, Bumblee and Transformers: Rise of the Beasts.

Mirage also later puts the Unicron threat into perspective by telling Diaz that "he eats planets." One of the other human leads in Transformers: Rise of the Beasts is featured in this trailer, too.
