Nikki Chan has a hidden alternate victory animation. If you wiggle the D-Pad and press buttons rapidly during her "drop to the ground" win sequence, she will show a peace sign.

Dragon, Shaky Jake, Nobunaga, Major Gaines, Fox, and Crimson Glory each have a "Cool", a special hidden continue screen where they will make cool poses and faces, sometimes while dressing up in sunglasses or a wig. To see their respective cool screens, you need to do the following tricks during the second victory round of a match (the second round in which your Warrior wins), in Versus mode:

• Dragon - Win the second round without taking any damage and do not use Left Shift, Right Shift, B, sweep-forward, or sweep-backward. Dragon will also say his special message about the losers of the internet.
• Shaky Jake - Hit your opponent with three fireballs during the second round.
• Nobunaga - Win the second round using only the A and C buttons.
• Major Gaines - You must let eight grenades explode on the ground during the second round. This means that the fuse on the grenades must expire on their own, and grenades that hit your opponent do not count.
• Malcolm Fox - Hit your opponent with the voodoo dizzy dust 10 times, but do not use voodoo dizzy dust until the opponent recovers during the second round.
• Crimson Glory - Win the second round without using the A, C, Right Shift, or Left Shift. This means that you must use only Crimson's block attacks to win.
