This glitch is fairly simple. The steps for how to do this glitch are listed below:

Steps:

1.) In Brawl mode at the character selection screen, select the character(s) you want to have the same color as each other.

2.) Next, choose the color you want with one of the characters and close that player so that that player slot is empty, but DO NOT CHANGE THAT CHARACTER ONCE SELECTED!!! JUST CHANGE THE COLOR!!!!!

3.) Now, go to the next player and choose the same exact color that you chose for the first player and close this slot down.

4.) Simply repeat steps 2 and 3 until all of the players have the same color as each other and have all player slots closed.

5.) From here, go to team battle and open up all the player slots and put all the players on the same team so that all 4 players are all on the same team as each other and it won't let you start the brawl because there are no opponents to face. For example: Players 1, 2, 3, and 4 are all on the Blue Team.

6.) At this point, go back to the regular brawl (no teams) and you should notice that it says start the battle when all 4 of the players are all the same color. For example: Players 1, 2, 3, and 4 are all Blue Marios. Once you start the brawl and move on to the stage selection screen, select the desired stage for battle and you should see that all 4 players are all the same character and all have the same exact character color!

Once you leave the brawl and return to the character selection screen, the character colors have changed to all different colors even though all of the characters still remain the same. Simply repeat the steps and you will all have the same exact characters and the exact same character colors.

Please note: I have not tested this secret/glitch on Wi-Fi! While fighting with the same characters and the same character colors, you are not in teams! So, you can hurt anybody with anything whether you have the Team Attack option activated or deactivated. It will be just a regular brawl.

*You can do this glitch with both Human Players or CPU (Computer) Players.*

*If you can't follow or understand my instructions/directions, please watch this YouTube video demonstrating this secret/glitch:*
