Wolfen (Star Fox series)
The Wolfen is piloted by the Star Wolf team in the Star Fox series. It, too, like the Arwing undergoes changes in each Star Fox game. It first appeared in the cancelled game, Star Fox 2, on the SNES/Super Famicom. The exterior of the ship makes it appear to be more complex then the Arwing, but it is can perform no more functions then the Arwing itself can. Star Wolf pilots a Wolfen in a few stages in Star Fox 64. Its final appearance in Star Fox 64 is on Bolse. On the Alternate Venom, a new, more powerful ship, the Wolfen II, is flown by Star Wolf.
The Wolfen appears again in Star Fox: Assault, where Star Wolf once again pilots it. Though not a Wolfen II, it is upgraded and is expected to be at least on-par with the Arwing. Possibly better...
The Wolfen can be unlocked in Star Fox: Assault after 150 versus matches. It has a larger auto-aim window then the Arwing does, and it deals more damage at each laser level and with a charged laser. It also flies faster then the Arwing but it cannot come to a complete stop in mid-air.
