THIS KI Announce Vocals wav file. You'll recgonize most of his announcements, but keep an ear out for a few mystery ones, and then read below.
From user wtihhei on an old Nintendo Forums board:
I have an old "Club Nintendo" magazine (when it was edited in Chile), that says that in that game there was an ultra-hidden character called "Shade" (or something like that), but according to that magazine, "Nintendo didn't want to reveal the code to get it, because that would cause lots of bugs in the game"... well, after some time I forgot about that matter...
But now, I read in a forum a list of the sounds present in the game (with their corresponding hex code), and I found two little surprises:
In the announcer voices (the ones that sound when you pick a character), between the sounds of Cinder and Eyedol, there are 2 sounds corresponding to supposedly secret characters not documented/mentioned anywhere...
0x5f2: HEAT SHADE
0x5f3: PYROTECH
An hypothesis I thought about, is that they could be alternate names for Cinder, but I also remembered that in the Beta version of KI (commented in the same Club Nintendo magazine, but lots of time before), there were other alternate names...
CINDER = MELTDOWN
SABREWULF = WEREWOLF
...so if this were the case, there would be also these announcer voices present in the game, and they aren't =/
Well, after all this text, I'd REALLY like to know: is effectively true that there is/are one or more hidden characters (besides Eyedol) in the game and Nintendo/Rare really didn't want to reveal the code to select him/her? or those sounds truly meet my hypothesis and are only consuming space in the game?
