Fox McCloud is a main protagonist in Super Smash Bros. Crossover starting with Season 21 after fading into obscurity. In Season 7, Fox and Falco attempted to fight Titanium Mecha Sonic, but were soon reduced to the sidelines. In Season 10, Fox and Pikachu fought Meta Knight after his betrayal, and nearly won, but got captured by a brainwashed Samus Aran. Fox was one of the characters that didn't move to Smash City, but he reappears in Season 21, where he is captured and imprisoned by the villains.
Fox's appearance is based off his appearance in Brawl.
Fox, unlike Falco, is calm and collected. Like Yusei Fudo he never acts recklessly, and always thinks things through.
