Ken's Shoryuken:
Megaman can use Ken's Shoryuken if you get all of the energy tanks, all of the hearts, and all of X's parts. The capsule for the shoryuken is in the third x-hunter stage (Agile). At one point in his stage, there is a ladder with many bats around. Use the Crystal Hunter to crystalize a bat to reach the ladder. Follow the path until you reach a downward path. Scroll on the left side of the path until X discovers a passage. You must be at full power for the capsule to appear. Dr. Light will give you Ken's Shoryuken.

Diagnostics Test:
To see the Mega Man X2 diagnostic test, hold the B button on controller 2, then turn on your system. Keep holding until the test appears on screen.

Alternate ending screens of Zero:
If you don't collect all of Zero's parts and beat the game. You will see a black-armored Zero at the ''Thanks for playing!'' screen. But if you collect all of Zero's parts and beat the game, you will see the original Zero at the ''Thanks for playing!'' screen instead.

Disappearing Enemies:
This will work with almost any enemy that can be frozen with the Crystal Hunter. Freeze the enemy with a normal shot then pause the game. Now at the pause menu select the X. Buster and hit start. The enemy that was frozen will no longer be there.

Harmless Sigma/Red X-Buster:
To do this trick, you must have all of Zero's parts and the Flaming Dragon Punch. First, go to the last Sigma stage. Right before you enter the room where Sigma drops in, stop. Dragon Punch your way in and try to land where Zero will punch his hole after the dialogue. If done correctly, X will fall through the hole when Zero punches it out. When Zero starts talking, do not let his dialogue disappear. Leave it there until X lands in Sigma's room. When Sigma enters, make Zero's dialogue go away and X should be able to walk over to Sigma. Have X stand right by Sigma, and when Sigma begins to fill up his energy meter, Dragon Punch him.

When the fight begins, Sigma should not be able to harm you no matter what he does, making it easy for you to conserve you SubTanks and energy for the second battle. Also, this glitch makes your charged shots look a vibrant reddish-pink color.

It will stay this way until the second Sigma battle begins. Also, using the Giga Crush causes your X-Buster shots to go back to their original color.
