Co-Op Event 10: The R.O.B.'s of Tomorrow

The R.O.B.'s of Tomorrow (, Asunaro Robot) is the 10th co-op event match out of a total of 21 in Super Smash Bros. Brawl. Player 1 controls, while player 2 controls. The two players need to work together to KO five s total. However, the R.O.B.s are not all the same size. The first R.O.B. is regular sized, 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 much smaller, but its attacks pack a surprising punch.

Trivia

 * If Lucario uses its up tilt when the event starts, it has a slight chance of KO'ing the first R.O.B. when it appears on the screen.
 * The music track used for this event is Tunnel Scene (X), otherwise unavailable on Summit. The track is normally used on Lylat Cruise.
 * The Japanese title for the Event Match and the overall premise of the event, featuring R.O.B. gradually growing in size, references the Thujopsis tree and its mythos within Japan; a tall, sturdy tree, it reportedly received its Japanese name, asunaro, from a famous allegory: "Asu wa hinoki ni narou, loosely translating to, "Tomorrow I am going to be a hinoki cypress".
 * Lucario and the Ice Climbers first appeared in the The Glacial Peak in the Subspace Emissary. This event match could be a reference to that.
