Patrick had been stranded on Mars due to a technical error, his crew left him behind.
Pat was a geologist by training and he had joined the mission to Mars. Started under the dying days of the Trump administration it was an effort by a dying superpower to prove it had superiority of the US of A over China. Patrick or Rick has he preferred had been the first to find prehistoric signs of life on Mars.
There were signed of forts that were built in a straight line, stone pots used for cooking, but for some reason no remains of the Martians could be found. The new president, Trump's son-in-law, was looking for a way to convert Martian technology into weapons.
There was none. He was sitting in his habitation. The canister with Martian soil thawed from the subzero temperature from Mars to the Earth's temperature inside the air tent.
As people were running "Bring Rick Home" campaigns he sat under the air tent as the martian dust was thaw for the first time in billions of years.
Rick inspected the canister when the lid popped open and he was engulfed in a cloud of black dust. It went through his nose and started slipping into his blood stream like carbon monoxide. The alien DNA mutated and bonded from Martian to human, his body started to undergo extreme changes.
His muscles started to grow in mass as blemishes like birth marks were removed. Rick's memories of being homosexual and having a boyfriend were transformed. His one time with a girl became magnified by his altered brain chemistry. Pussy was the only thing that mattered.
His penis lengthened to burst free of his foreskin, then pulled back in like a canine penis. After several hours of engineering his vision, hearing and smell were boosted to levels that rivaled fictional characters like Superman.
Now an alien hybrid the human skin was a disguise to return to Earth.
