Sunstreaker is very much like his brother, just more arrogant. The autobots don't get along too well with him, because of his tendency to be unorthodox in most subjects, and because he demands everything to be done neatly, which is why he prefers long range guns than melee weapons, unlike his brother. He avoids physical confrontation at all costs in fear of getting his shine and polish dirty or damaged, but isn't afraid to get into a smackdown with a Decepticon to show off his weapons and abilities, and since he is 100% sure he will be the winner, he's willing to sacrifice a bit of regenerable body paint in order to plant a flag onto his enemy's skull. His weapon of choice is a cybertronian plasma rifle, which burns through thick armor with a few shots. He's every bit as quick as his brother, despite his somewhat burlier appearance. He's also capable of short range flights. His alt mode is an old school Ferrari F50 (upon entering Earth). He is cooler than Jazz. Difference is...Jazz was nicer.
