@Victormg How absolutely shocking that my desire to ejaculate in the rectum of a fictional 2D character indicates that I am homosexual! I never would have guessed!
ONE is creating a story background for flashy, leading up to his old comic, where flashy flash meets saitama. Makes sense because without GPS-thing, flashy flash wanders around inside deep maze until he meets saitama.
@Damoon inb4 they meet each other, think they're monsters (or at least, Flashy Flash might), fight, flash gets rekt, and then OPM realizes, wait you're a hero
I wouldn't put it past ONE or Murata (and I haven't read the original, so this is just guesswork) to do it just for comedy
Losers: why can't we beat you. we transformed into monsters to gain the power and speed to kill you so tell me why! Why can't we beat you
Winner: you're training is lacking
