if I don't understand your point, its probably because your not understanding mine,
I will say it again, until the waddle dee that king dedede is throwing has a bandana on it, it is NOT! his right hand man
and the reason why he throws a generic waddle dee is simple, during brawl time the only thing he had was a minigame appearance, and a major part of one of the sub games in super star ultra, that's not really enough now is it? but now he has gotten a cameo appearance, a major importance as well as being playable, being shown on the title of Kirby 20th anniversary, and a new role in triple deluxe, back then he was probably unrecognizable, but everyone knew what a waddle dee was, so they incorporated part of king dedede's army into his moveset, now every Kirby fan recognize him, so its impossible that they will leave him out this time, but the question still remains if he will become king dedede's side B? but with I have showed you shows that he actually has gained importance being his own character, if he wasn't important, he wouldn't be shown in Kirby 20th anniversary, now would he?
but the final kicker, the thing that gives him a great edge is actually Rosalina, with her confirmed, it shows that left fielded characters that can provided something unique to the game can get him over others, bandana Dee shows that with flying colors. bandana dee has great chance to not end up replacing the generic waddle dee king dedede uses, and instead be he his own character.
nah no one forgot him, we actually discussed that he should be bandana dee's alternate costume
