In this universe or timeline, things went a bit different. Harry stabs the basilisk an the fang scraps the scars and plunges into his thigh, right next to his privates. The scar bursts and the Horcrux screams. The Diary Tom yells out no. Harry realizes that they are the same. The horcrux was an older Tom. He grabs the fang out of his thigh and plunges it into the diary. This let the head of the basilisk fall on his thigh. Fawkes had to fight to get to Harry's thigh. He wept three tears and looked at Harry to see if he needed more.
That is when he saw the scar. He wept one more tear then got to his messed up forehead. He wept over more tears, till he had done, the maximum he could do. Harry had an out of body experience. He was many heroes in many dimensions. He was Flash and his body bulked up, learning other sports and schooling. He was Batman and his body learned all the different arts of fighting, while his brain took in all the technology and learning that Flash Goran did not have.
He was Merlin, the half Incubus. His body changed, more than the basilisk had done to his small (no longer) balls and tackle. He learned wandless, staffless, and staff fighting and magic. His last 'life' was Tak-Ne or Juan Sánchez-Villalobos Ramírez, an immortal that can only die by having his head cut off. Harry now could fluently speak Egyptian, French, Spanish, Latin, English, Chinese (Han), and Japanese. He was also a master swordsmith and swordsman. A sailor (and pirate), a charioteer, a bowman, a sword and shield man, and all a worker, if not master of all the early pre-industrial skills.
His body changed, backwards in time, so that the AK did not work and bounced off him. He now had no scars, with the Horcrux gone, his forehead healed. His super magic fixed his eyes. He had ann allure, but only on those he concentrated on. Harry was now a genius in technology, wandless magic, and being a sexual predator. He thinks of Hermione, but then of the poor blonde he was sure was being abused in Ravenclaw, to the small Su Li and Parvati's twin Padma. Which leads to Parvati and Lavender, the gossip girls. Then of the cute Redhead in Hufflepuff and the other maroon haired girl Megan Jones. This leads to the only two in his year that now trips his trigger. The two blondes in Slytherin, one cold as ice, the other as open as a flower in sunshine.
Fawkes is now not to sure that he should have cried so much on him. He can sense the predator instinct in Harry, but it is not evil. More a longing for family, bit it is a bit strange to him.
