This past weekend at HasCon, Hasbro unveiled an all-new Transformers Dinobot Combiner named Volcanicus, and now we know when they will debut. Volcanicus will be a playable character come September 21 in the Transformers: Earth Wars mobile game.
The Predacons Combiner Predaking will also be available to play in Earth Wars at this time, as part of a "Combiners Saga"level and event story co-written by Simon Furman.
Here is a trailer:
And toy fans will be able to assemble Volcanicus for the first time in Spring 2018 out of five new Dinobots toys part of the Transformers: Prime Power of the Primes series - Grimlock, Slug, Swoop, Snarl, and Sludge.
Volcanicus is the first canon Dinobots combiner, as The Beasts Within's Beast has never been formally recognized by Hasbro.
