Hardman NGX (also known as Ken Johnston (Human name), Juggernaut, The Invinsible, Destroyer, and the Champion) is one of the main antagonist in the Megaman NGX Series. He often proclaims himself a champion and challenges random people to battle him to prove that he is stronger, which he is in most case. The Galactic Alliance label him as a Upper B Rank fighter, due to his strength and put a bounty of 500,000,000 Zenny ($50,000,000,000)
