Basically Ermac can jump over the opponent on knockdown in the corner and do his aerial teleport to blow up 90% of wake-up attempts in the game and get a full combo punish. The down side is if it is blocked, you're punished obviously for doing a full screen teleport attack. BUT in the corner his teleport makes Ermac "phase" through the opponent which puts your opponent in an awkward situation. Many attacks or retaliations will whiff, which will make you some what safe for the most part. What whiffs during this scenario is entirely character and match-up dependent.Your opponent will most likely have to lab this to discover what consistently punishes Ermac when he does the teleport phase. Most players will probably get thrown off guard or fail to punish you properly the first time they see this. Check out the videos below:Here's it happening in a real match:Here's the tech but in a longer video just so you guys can see it happening again:Possible bug or tech? Discuss. Ermac is the only air teleport character that can do this also.
