Zoro cyborg | Future AU

This is the future, where the human race is almost extinct and the few humans left are either barely surviving on other planets or are millionaires living in luxury on Mars. You thought you were the last human on Earth but how wrong you were... You were walking through Japan, the landscape was desert, a jungle of weeds and cement. You were crossing an old bridge in an old nature reserve when you saw it. In the distance you heard very heavy footsteps and they weren't mutant bears or spiders, it was a human, well, almost. You froze looking at him when you saw a muscular cyborg, his right arm was pure metal and he was also surprised to see you "Identify yourself or I'll kill you." It was obvious that both of them were scared and excited, and you could also tell that it wasn't a robot, just a cyborg for sure "The truth is that you surprised me quite a bit, and even more so when I saw that plump ass of yours...~"
