A significant shift has recently occurred in the Dragon Ball Super manga's Super Hero Saga. Time has advanced sufficiently that all of the children now resemble teenagers. This includes Goten, Trunks, and the Pilaf Gang. Three of these five, however, should raise eyebrows among the Dragon Team.
Despite previously enraging the Dragon Team, the Pilaf Gang has gone unnoticed throughout Dragon Ball Super. It was one thing when they were transformed into children, but now that they are adults, they ought to start to resemble who they once were. There may be a few ways to react to the question of whether the Dragon Team has yet to act in response to the Pilaf Gang's possible threat.
What Should the Dragon Team Do in Retaliation for the Pilaf Gang?
In fairness, only a handful of people would recognize the Pilaf Gang. The original Dragon Team of Goku, Bulma, Oolong, Yamcha, and Puar should all remember these guys as the last hurdle in their first quest for the Dragon Balls. Piccolo Jr. might know of them since King Piccolo worked with them, but he's never personally met them. Chi-Chi technically met them in the anime, but it was a non-canon encounter, so it's okay if she doesn't remember them. Other than these people, nobody else in the Dragon Team ever came face to face with the Pilaf Gang.
When they were introduced in the God of Destruction Beerus Saga, it made sense that no one knew who they were. Besides the fact that it had been over two decades since their last encounter, the Gang had since turned themselves into children. Even if anyone thought these kids looked familiar, they wouldn't have an explanation for how they became children after so much time had passed.
The first big chance anyone had to recognize any of these kids was in the "Future" Trunks Saga. During this arc, Future Mai came to the past looking like her adult self not counting a negligible style change; if Trunks' blue hair can be ignored, the same likely applies to Mai's changes from her old self. Bulma might have recognized Mai by this point but didn't say anything in light of her friendship with Trunks.
Beyond that arc, most of the Dragon Team had excuses for not recognizing the Pilaf Gang: Goku wouldn't remember them because of how DBS has dumbed him down; Yamcha, Puar, and Oolong haven't had a chance to recognize them since they've hardly been in the story let alone the Super Hero Arc. The only one who doesn't have an excuse for not remembering these three is Bulma, who's both smart enough and has spent the most time with them.
Does Bulma Simply Not Care About the Pilaf Gang or Does She Not Recognize the Gang?
Bulma seems to recognize Pilaf at least, but she doesn't register him as a major threat. She even has his gang working for her. If they cause trouble, she's quick enough to call them out on it and put a stop to it. In other words, even if anyone sees these three and remembers the start of Dragon Ball, they have no reason to fear them.
As a result, the Pilaf Gang as it once existed has largely disappeared into obscurity. Bulma is keeping a tight check on everything, so that day might never come when they assemble the Dragon Balls and do anything risky with them. Other from this, the trio has successfully assimilated into the main cast and doesn't seem to be causing any major problems. Even if someone did recall who these three are and what they've accomplished, they most likely wouldn't make a big deal out of it because it is no longer noteworthy.
