Fairy Tail: the Mediocre Doomsday Superman

[Invincible➕Shuangwen➕Plot magic change➕Multiple women] Al traveled through time, and although he didn't know why he became Natsu's older brother, when he woke up and saw Natsu crying in his arms, he could only recognize this little brother. He originally wanted to hug his little brother's lap, but he awakened the Superman system. However, because the system was attacked and turned into a mutilated body, he could only become Doomsday Superman and then self-destructed. So he could only become stronger with self-discipline and hard work every day. Natsu: Self-discipline? It's really self-disciplined to insist on sunbathing every day! Lucy: Try hard? ! Is it called hard work to insist on going to the place where the sun is the strongest every day? ! Al: Otherwise, why would I become stronger? It's not because of my self-discipline and hard work! After all, I am so ordinary! Everyone in Fairy Tail: Shut up! Black Dragon Akuro Nokia: mediocre? Will Ping Ping Wu Qi suddenly fly up and hold me down and beat me wildly? ! ! ! (Because the protagonist's abilities are somewhat beyond the standard, the plot will be greatly changed, and the people closest to him will be greatly improved, but only for Natsu!)
