Rumours persist of an incredibly powerful superhuman. Like The Shark this man was supposedly impervious to all harm, however it is said that this was not due to invulnerable skin but because one of his powers was a form of hyper-adaptability: his body could adapt to any circumstances, so he could be injured, but only once by any specific form of weapon. Combined with his rapid-healing factor and his indefatigable endurance, this made him an extremely tough opponent.
