ROB is probably one of the best all rounded characters in the game. He can play both long and short range with ease, his airs are amazing, exceptional recovery, and great power. A fun thing lots of rob layers do is short hop and Nair because it clears the room around them, every ROB player's favorite combo is probably down throw to up air because it guarantees a kill. I'd recommend every smash beginner to use ROB because they can play more easily, take advantage of his power, and feel safe with his amazing recovery.
