Michael Heddington

Michael Baldington Heddington was a former Space Prince turned frustrated man with a receding hairline.
He was born on the planet Krull to a noble family and rose to fame after defeating the Galactic scourge known only as The Beast. After leaving the planet, he soon realized he was something of a celebrity, the fame and prestige going to his head.
He eventually succumbed to the temptations of fame: gambling, substance abuse, and women. He gambled away his family fortune and was left pitiable young man with little future. Retaining his good looks, he became a citizen of the money-less Federation, joining Starfleet inspired by the tales of the handsome swashbuckler Jim Kirk. 
Later in his career, his frustration over his incurable male pattern baldness lead him to lash out and rebel against Starfleet.
Federation's screw up over the Fountain of Youth Planet was the last straw so Balding-Heddington lead an open rebellion using the Maquis as a cover to get closer to planet. He was then appointed Big Mac of the Maquis.
Heddington's extreme vanity and irrationality drove Benjamin Sisko crazy. Sisko chose to shave off his own full head of hair, as a direct statement against Heddington.
