I cannot believe I'm saying this but I'm actually having trouble with him as a freaking ROB main, the piece of garbage just corners me and I'm scared of that side b like its the plague and I'm too scared to go offstage
A ROB main that's terrified of a Side-B is the ultimate irony.
On topic, there's a few things you can do to make life easier:
• If you can dodge or block his smash attacks or specials, you have a free punish
• His grab has a pathetic range for such a large character
• Don't shoot your fully charged neutral B unless you know for sure he can't/won't Revenge it
• Be wary of using charged Smash attacks if he's near
• ROB has far better air mobility and recovery than Incineroar. If you knock him off, there's a good chance that he's going to be unable to come back at high %s
• If he manages to score a Revenge on you, he's most likely going to follow it up with a Side B or a Smash attack, both of which have pretty poor range compared to ROB's tools
• His low % combos will always start with a Dthrow to Fair
• If you're above 100%, he can easily UpThrow to UpAir for an easy KO
• When you get over 80%, stay away from the edge of the stage. His FThrow can easily KO you
