Justicar is the featured hero at the official Champions Online site. Featuring links to concept art, comic origin and a thumbnail sketch of who Justicar is, there is also a terrific story to go with the rest:

David Burrell had it all - good looks, intelligence, athletic ability, and a family fortune that could pay for a life of privilege and comfort that most people only dream of.

But none of that mattered to David - he'd rather be climbing a mountain than standing atop the pillars of the business world. Drawn to a life of adventure in the great outdoors, he gave up his place in the family corporation to climb the mountains he loved, and found joy and peace among the snowy peaks.

David was climbing Mount Assiniboine with a friend when an ice sheet gave way. David plunged more than fifty feet, landing on a ledge and breaking his back. Paralyzed and helpless, David begged for death. Instead, he was rescued, but in addition to his other injuries David lost a leg and a hand to hypothermia.

After years of rehabilitation, David learned to walk again. He found new purpose as a crusader for the rights of the disabled and looked upon his prosthetics as a badge of honor.

It's worth the time to go visit so why don't you?
