    Metal Bat Could Have Taken Down Garou

    According to illustrator Yusuke Murata, Metal Bat's fight with Garou would have ended a lot differently had Bat's sister Zenko not intervened. So differently, in fact, that it would have been the end of Garou's life, and many of the scenes in the second half of Season 2 would not have happened.

    Tatsumaki's Fight Against Ancient King Was Misunderstood By The Animators

    In the anime, when Tatsumaki battles Ancient King, she drops a meteor on him. This was apparently the result of the animation team misunderstanding what ONE intended. Tatsumaki was only supposed to drop a boulder onto Ancient King, which was supposed to trigger a flashback to another time when he'd been hit by a meteor. ONE says that if Tatsumaki could actually do that, she would also have been easily able to take down Boros' ship.

    Watchdog Man May Be Based on A Famous Dog

    Watchdog Man spends most of his time observing the city from his pedestal. This might be based on a real Japanese Akita dog named Hachiko, who is a famous symbol of loyalty - he would meet his owner at the train station every day after work, and continued to do so for ten years after his owner passed away. There's a statue to commemorate Hachiko in Tokyo.

    Flashy Flash & Speed-o'-Sound Sonic Have A Connection

    When ONE was asked whether Flashy Flash and Speed-o'-Sound Sonic had any connection, he avoided the question. That's likely because he didn't want to reveal what was planned for the manga: the two are from the same Ninja Village, and are from its 44th graduation class.
