Yeah, thanks! And I must have misunderstood... I was thinking you guys meant Ermac's tele-slam, meaning DB1.@STORMS
Ermac can cancel the air slam aka "butt slam" by taping down twice. When down is tapped twice you fall back to the ground. Good tactic to use from a safe range against certain chars. Could bait mistakes and you build meter. Air slam could also be canceled by an aerial special, like the teleport or the air blast. Air slam could also be delayed in the air and you could stay hovering for a while by holding block.
