Wolf is the main villain of Battle Arena Toshinden URA. He used to be Ronron's superior on the Toshinhei project. As soon as she made the Replicant android, Wolf planned to use the android for a deadlier purpose and stole the Replicant. Wolf then changed Replicant from a law enforcement robot, to a martial arts killer and sent it on a killing rampage. His plan was to make multiple Replicant androids to do his bidding and use them to rule the Earth. Ripper was not about to let that happen. He charged in and then cut Wolf down.
