My first thought when I read on the chapter that giving Gearshift to Tomura was making him nostalgic bc Kudou tested out how to pass the quirk without the other party wanting to receive OFA ^^' Like did you just use Bruce as a guinea pig?
An unstoppable force (Kudou wanting to test out some new crazy idea he just had) meets an unbreakable wall (Bruce's common sense)
"Don't mock Captain Hero - a ticklish lesson for Kudo"
... and don't pull reckless stunts while fighting All For One's organization! These are the lessons Kudo, the second One For All holder, is learning the hard way.
I don't know much about Yoichi, Bruce and Kudo, so these interactions might be out of character in canon. However, I have read fanfictions where Yoichi, the first OFA holder, shows Captain Hero to Kudo and he often thinks it represents a parody of the hero genre. Also, in those fics he tends to find hero (an villains) monologues insufferables. On the other hand, I have read some fics where Kudo acts in a reckless and self-sacrificing way due to some issues. Consequently, I used all these elements to create this scenario inside the Void of One For All, where Kudo accidentally offends Captain Hero in front of Yoichi, who decides to punish him for this, with the help of Bruce, the third OFA user, who wants Kudo to pay for being a reckless sacrificing idiot and worrying both of them when they were alive.
In the end, I just wanted an excuse to draw the stony second OFA user laugh.
"If you stare into the abyss long enough, it may stare back."
Whose hands are these? These are the hands of Yoichi, Bruce and Kudou. Unlike Destro, they passed away too quickly, leaving Chikara alone with the monster.
