Benwolf is the Codon Stream's DNA sample of a Loboan from Luna Lobo. Benwolf first appeared in Benwolf (episode). After the Omnitrix was scratched by the Yenaldooshi, it got stuck between Active Mode and Capture Mode, making Ben turn into Benwolf slowly. Wes thought Ben was turning into a Yenaldooshi because he was bitten by it as Wildvine. However, after the Omnitrix symbol appeared on his stomach, they realized that they were dealing with an alien werewolf. Benwolf turned back after he dropped Max and Wes on a cliff. Benwolf is a very strong alien and also has a Sonic Howl and enhanced hearing and smelling, but he is colorblind.
