When the fight begins, press Away, Forward, Y. He should charge at your opponent and do a series of punches which gives you a 11-hit combo.

To normally get these achievements, you must complete the game with all characters in Arcade mode from each side.

Choose a fighter you have not completed Arcade mode with yet, and defeat Dark Kahn with him or her. Also, it is much easier to play on the Very Easy difficulty so you can defeat Dark Kahn easily with the characters you are not familiar with.
