I knew someone would post something like this...
Well, I can't argue that Peach is definitely an awesome character, she has the power to redirect any attack in the game with her regular B technique. Not to mention her evasive and recovery abilities that are insanely easy to use. Unfortunately though, I certainly cannot agree to characters like Toad and Sonic characters.
When people play SSBM, they can use a program called Action Replay that is an advanced version of most cheat software. It literally reprograms the game so certain things can be done such as a Toad character. Any picture on the net is also easily edited with any type of photoshop one can imagine.
A different example of a game using Action Replay is Kingdom Hearts 2. With this software, you can play as Mickey instead of Sora in the worlds and even use Forms in the Sephiroth battles.
Here's a vid of one of the multiple cheats:
KH2 CheatThe last reason why is because it wasn't in the Nintendo Official Player's guide. I'm pretty sure that no company would leave out important things such as secret characters without even giving a hint that they exist. Otherwise people would think twice about buying an incomplete guide.
It's no one's fault that they believe these and you're free to try them out, but I just want to save people the wasted time and effort. If any of these pseudo characters do exist, then they would be unofficial and unusable in tournaments. So please don't blog this thread with secret characters that shouldn't have been in the game, please keep it to strategies and help on any problems you may have.
BTW: Share any glitches you'd like, I know plenty of them that can kill in one hit... TRAPBOX!!!
