The R.O.B.'s of Tomorrow is the 10th Co-op Event Match in Super Smash Bros. Brawl. Player 1 controls Lucario, while Player 2 controls Ice Climbers. The two players need to work together to KO five R.O.B.s total. However, the R.O.B.s are not all the same size. The first R.O.B. is small, and the next R.O.B.s are successively bigger, with a colossal R.O.B. as the fourth opponent. The last R.O.B. is small, but it's attacks pack a surprising punch.
