Powers of the posthuman: number1: super strength.

We've all wanted ridiculously over powered muscles at some point in our lives whether they be for hurling tanks hundreds of miles or leaping from country to country.

To a post-human even the heaviest objects in existence weigh less than a grain of race even though they could weigh untold amounts of tonnage.

Of course not all post-humans have to have god-like strength some more down to earth post-humans can have strength that is simply enhanced to beyond what any human could handle.

They can lift heavy objects such cars and small trucks, run faster than a speeding car (not a race-car obviously) , leap 5 stories up and at least 40m out , crush steel bars , punch or kick through solid brick walls , survive intense beatings and generally perform better at all sporting events.

If a criminal was given enhanced strength their would be no telling the destruction they could cause. Anyone caught in one of their attacks would be utterly destroyed their skull crushed like an egg, their could kick right through a police mans body killing them instantly, they could cause horrible acts of terrorism with their bare hands alone causing major catastrophes left and right up and down. The moral of this is don't inject a top secret formula for enhanced strength into a criminal since their brain wouldn't be able to handle the enormous responsibility such a power has to offer.

On the other hand if you developed a formula that increased someones brain power as well as their strength then you would have a truly unstoppable being. With the right training and tools they could defeat anyone who challenged them, combine their adrenaline with their already enhanced strength to become almost unstoppable , do things that seem impossible such as leaping off a building without getting injured and survive being shot multiple times.

Even this could have side effects since a person who has super strength isn't invincible just very close to being ,to fix this problem your going to have to give them invulnerability to all damages of physical damage. This way nothing could defeat them except for beings with powers and intelligence far beyond what they could ever hope to accomplish. Bullets would fly right off them, bombs wouldn't even scratch them and fire wouldn't cause a burn.
