Excellent theory. However you state it as though it's fact. I would like to see your proof, please.

Anywho, why would Kirby and Zelda have to be unlocked? That would be a stupid idea. Triple-D on the other hand, could be an unlockable. If you read somewhere in the Dojo, it says, and I quote,
"When you have a battle mode that runs online like Basic Brawl, the problem of what to do with hidden characters arises. If one of your opponents chooses a character you haven’t unlocked yet, it will be spoiled for you immediately.
But even without this mode, given the proliferation of the Internet these days, the existence of hidden characters is going to get exposed anyway.
So, this time I’m moving in the direction of not being too hung up on hidden characters.
You can earn most characters by playing through Adventure Mode: The Subspace Emissary. For those of you who look forward to those encounters, I recommend you clear this mode before playing Basic Brawl.
And as the case has always been, I’ve made it so you can play the characters you unlock in battles."
This is a great idea to me.
