MC is a girl in a girls body. No penis.
The MC has a poor life, he first gets abused by his uncle, then abused by some god, then held captive worse than an animal for many years, only to be killed by his former classmates. There is not a single person who has some love for him. Until his last rebirth. He gets to know his loving new mom and his mind gets it's first break after 30+ years of mental torture. But those peaceful days will not last. The MC's mother gets killed (you could see that flag from miles away) ; she gets tortured and burned alive. The MCs mind gets corrupted, he swears revenge. But he is too weak. He levels up and comes back. With his new found power and minions he goes to destroy the city's wall's so that the citizens have to fend against wild animals and also spoils all the fermenting wine so that the city loses its production. Totally badass.
PS: Also the MC is one of the bread-hating asians, not making him any more likeable.
face changing and
It starts Konan-esque by solving mysterys to get relicts that provide skill points. The MC often has no idea what to do even though he has an attribute called Intelligence. Instead he levels his strength to pick up martial arts. The martial arts take over and the story evolves into Fist of the North star. This goes on until Garen becomes the strongest man alive, fighting a sorcerer community until someone drops a nuke onto him. The end? No! Garen gets transmigrated another world where he starts similar to Warlock of the Magus world, but with totems instead of spells. Some more random acts happen until Garen transforms himself into another uber-mensch, going on another rampage. I stopped when he got a device that reminded me of the scanner in DBZ. Its over 9000!
the poor, bullied MC actually used to bully people a lot, harbors sense-less grudges because of his low social standing, has the "best girl in town" be at his call -actually started the romance sub-plot during his childhood-days, has the hottest female teacher stand up for him, manages to disregard the face of the biggest big-shot of the best family -and the big-shot actually reacts to the provocations of a 18-years old child-, and has op-powers and artifacts
