Team Star Fox
Team Star Fox is a team of mercenaries/adventurers that consists of Fox McCloud, Falco Lombardi, Slippy Toad, Peppy Hare, and, late in the series, Krystal. Another character, ROB64, is a member of the crew, but is not a pilot. He instead runs the Great Fox and handles repairs on the Arwing, the fighter ships of Star Fox. Tricky is also a member, but does not adventure with the group. The team was originally led by Fox's father, James McCloud, and his teammates Peppy and Pigma. After Pigma's betrayal and James's death appearent, Fox took over the team.
Appearances in Smash Bros. Games
Fox and Falco have both made appearances as playable characters in the Smash Bros. games, though Falco did not appear until Super Smash Bros. Melee. Slippy and Peppy have appeared as trophies in both Melee and Brawl, but Krystal and Tricky have only been a trophy in Brawl. Slippy and Peppy also appear in Falco and Fox's secret taunts performed on Corneria and Venom. All characters (excluding Tricky), however, appear in the secret taunts of the Lylat Cruise stage.
ROB, while never technically seen, is always within the Great Fox, the mothership of Team Star Fox that has made an appearance in all three games.
