Wavedash
The Wavedash is a useful technique/glitch, and is an advanced dodge move, in Super Smash Bros. Melee. It is done by Jumping, and then immediately air dodging toward the ground so your character will slide along the ground. It can be done by holding the control stick in the Down-Forward (Or Down-Backward) position and the Pressing X~R~X~R~X~R extremely quickly. X to jump, R to airdodge. The Wavedash is an extremely difficult technique to master and you need to test with your character to find the exact timing. While wavedashing, you can go as fast as, or faster than a regular dash, can attack with any attack out of your dash, and can change directions very quickly. As good as this sounds, it's not THAT useful to most characters. Luigi's is the easiest to see because he slides so well. Wavedashing can be used to put space between you and your enemy. Yes, rolling creates space, but when you wavedash, you can use any attack/jump/special move right off the bat and shorten the lag time compared to the roll. When practicing, you may want to start by air dodging far away from the ground, and start to air dodge closer and closer to the ground until you get the timing. The next step becomes harder, as you must repeat the process diagonally. This was removed in the sequel, Super Smash Bros. Brawl.
