Hellboy himself, Ron Perlman, has reportedly been cast as the voice of Optimus Primal in Transformers: Rise of the Beasts, according to Collider. Optimus Primal, the leader of the Maximals, was originally voiced by Perlman in the animated series Transformers: Power of the Primes.

Rise of the Beasts will introduce Transformers: Beast Wars lore into the live-action films for the first time--meaning there will be robots that transform into animals and vehicles. For those that don't closely follow the various animated incarnations of the property, that shouldn't seem like too much of a logical leap. After all, we've already seen Dinobots in the films.

As of this writing, Transformers: Rise of the Beasts is slated for a June 24, 2022 release. In the meantime, you can read everything we know so far and get up to speed yourself. You can also read our related overview of all the robots we know, so far, will have a role in the movie.
