volcanicus
Volcanicus is the fearsome combination of the Dinobots that was 65 million years in the making, and is now ready to deliver the Decepticons a world of pain. Considering the Dinobots' reputations as brainless brutes, Volcanicus is similarly a mindless beast as a result, but given how it hasn't stopped the Dinobots before, it's not much of a problem.
