Like Superman or the Silver Surfer, I would have to say No, unfortunately. Like Daredevil or Batman, possibly but very unlikely and not as powerful or capable as in the comics or movies. Not yet anyway. Advances in nanotechnology (or perhaps even smaller scale), bionics( for real), meta-materials, computing, and electronics and power sources advance though the future may allow things to change.
There are laws against taking the LAW into one's hands though. Vigilantism it is called. Assault, murder, are wrong. Superheroes don,t give people trials.
