Personally, I just use Megaton Press. Because I’m lazy.
However, when I get yelled at for sitting on 2 full meters (hey Mike!) I pull out the Gigas, and amusingly I only use maybe 1 or 2 setups. I don’t know why this works, but it’s been good to me.
On wakeup, do a fierce clap.
Everyone knows this one. It’s like, the oldest Hugo trick ever. But it works! You just have to anticipate your opponent and be fast enough to capitalize.
If they block it, they’re in blockstun long enough to dash forward and get Gigas’d. If they know enough to get the hell out of the way, pause a sec and grab them out of the air. Any other response should get sucked in by Hugo’s Mighty Hamfists of Grabby. If they parry, IMMEDIATELY do the Gigas and it should just eat them right up. You have to see this one coming though, so I would recommend doing the first 360 no matter what happens, then do the (cough 270) followup if you see the blue flash. If not, you’ll still keep the buffered 360 when you dash.
Buy hey, really, all I ever do is bait jumps and Megaton that ish down. Grain of salt and whatnot.
