The Wolfen occasionally flies by in the background of Sector Z, but does not attack the player.
A Wolfen appears in the Corneria and Venom stages, occasionally firing lasers at the characters on-screen. The Wolfen doesn't target any character in particular. In the Corneria stage, once it has stopped firing, the Wolfen will then fly off the screen after a few seconds. If a character remains on it when it flies off the screen, that character will receive a Star KO. It also appears in the opening movie, piloted by Wolf as he makes his cameo.
The Wolfen trophy is obtained by clearing Adventure Mode in under 18 minutes 20 seconds or less.
The Wolfen reappears in the Corneria stage as it did before and also makes an appearance in the Lylat Cruise stage. It appears briefly in both Wolf's on-screen appearance in which he ejects from it to enter on the battlefield, as well as a bonus scene of the Subspace Emissary, in which Wolf ejects from the Wolfen and lands on the Lylat Cruise to face off the player. It's also notable that the Wolfen appears slightly different than the Star Fox: Assault version, where its wings are spread farther apart. The Wolfen also appears as a sticker in Brawl.
A class of starfighter piloted by Team Star Fox's rivals, team Star Wolf. Wolfen's boast more gravity-suppressing plates than Arwings, making their performance equal or perhaps even superior. When Team Star Wolf reappeared, they were piloting Wolfen II ships--improved versions with two laser cannons rather than one and capable of reflecting attacks by rolling.
The Wolfen appear as a distinct trophy. Also, the Wolfen reappears in the Corneria stage.
The Wolfen appears as a distinct trophy. Its Assault version is an item in Smash Tour: when used, it makes a selected opponent start the battle with 100% damage. Also, the Wolfen reappears in the Lylat Cruise stage.
Wolf returns as a playable character in Ultimate, and once again his on-screen appearance involves jumping out of his Wolfen. His new Final Smash, Team Star Wolf, involves him and the rest of Star Wolf firing on opponents from their Wolfens.
