Optimus Primal is a evil Maximal in the Shattered Beasts universe.
"Till all are mine!"
Optimus Primal is evil, sadistic, and not to mention generally not nice. He took the form af a gorrilla as it was the most physicaly powerful of the avaliable beast forms, of course he added extra armor to keep his precious little furry butt safe but that's beside the point. He is incrediably devious and underhanded, being able to twist anyones words or actions to benefit himself.
