3) BROCK SAMSON
Known to friends and foes alike as ‘The Swedish Murder Machine’, Brock has spent most of his career as an agent of OSI, working as bodyguard for Doctor Thaddeus Venture and his sons, Hank and Dean. Though not usually a costumed type (though his time with SPHINX ((SPHINX!)) did involve a mask and bodysuit), he clearly lives and functions in a world of superheroes, fighting on a mostly even playing field with them and even dates the Amazon brawler Warriana, meaning that I’m perfectly comfortable counting him.
