ROB is evenish (or slightly loses to) MK, like 45-55?
ROB goes even or beats Snake (as most people say) 55-45 (maybe 60-40?)
ROB goes even with Dedede 50-50
ROB beats Falco, maybe like 65-35?
ROB loses to GaW, maybe like 40-60?
ROB beats Marth, like 65-35?
ROB beats Kirby, like 60-40 or 55-45
the only chara above him he has a clear disadvantage to is GaW, and besides that the only other matchup not in his favor is MK. Besides like the 2 or so odd matchups he loses to in high tier and lower, ROB generally ***** the rest of the characters when Kirby can have problems with dying far too early from being so late, and ROB is one of the heavier characters in the game. I don't know much about it, but I can't imagine Kirby doing too well on like a.... DK or something, whom ROB has a big advantage over.
edit: nice, m2k agrees with me lol
