Profile: Headstrong doesn't listen to anybody, particularly his friends. He's so certain of himself that he doesn't acknowledge others' opinions. He's smug and arrogant, and believes that everyone would be better off if everyone minded their own business. Nothing can dissuade him once has decided upon a course of action, no matter how foolish that course appears to be. And once he begins something, his commitment is total and unwavering. Knowing that he is not as strong, intelligent or fearless as some of the other Predacons, Headstrong puts up his stubborn front as a shield to hide his deep-rooted insecurity. Still, he makes a formidable foe. The best way to attack him is not with weapons, but with psychology. Question his resolve and his abilities and he's more likely to collapse from the weight of his own nagging doubts than from a direct hit by a laser cannon!

Abilities: In rhinoceros mode, Headstrong can achieve speeds of 60 miles per hour for short periods. At full speed, his horn can puncture a three-foot thick steel slab. It can also release a highly corrosive acid on contact, greatly enhancing its destructive capability. In robot mode, he uses a plasma sphere shooter, which emits a stream of energeon balls which explode on contact.  He also carries a distraction sword, which bends nearby light so that an opponent can't properly see where Headstrong actually is. Headstrong combines with his fellow Predacons to form Predaking.

Weaknesses: In addition to his knack for talking himself into foolish, dangerous predicaments, Headstrong often suffers from impaired mobility due to bearing problems within his joints. He also has very poor eyesight.
