I? I am a Monument, to all your sins.

The Beast is the combined form of the five Dinobots. Like them, his strength is awe inspiring, far beyond the other combiners. Unfortunately, he is also a mindless monster, whose single impulse is simply to kill, regardless of allegiance.

Fiction

With the Autobots moments from death (some several moments past death) Grimlock lays all his cards on the table and combines with his team mates into The Beast. After killing the Decepticon combiners, and any Decepticon foolish enough to attack him, he turned on the Autobots. Optimus Prime attempted to reason with him, but to no avail. The Autobots were forced to kill him. The Beast Within

Trivia

• For years, fans have been coming up with designs for a Dinobot combiner. This is so much worse than any of them.
