I believe it's Ike. Here's why: His D-Tilt will send anyone straight down to their death, even if at 0% damage, and his Up+B has a high strike, and can barely be dodged, if you use an air dodge in the right place going over Ike. He comes back down and, guess what, HE EDGE HOGS. It leaves you only your Up+B (if you have one)to get back up. Who do you think it is?
