The hot-tempered Wolf Imagin wields a sword able to launch crescent energy beams. When Yuka Sawada wishes to relive her high school days, the Wolf fulfills this wish by vaporizing high school girls and giving their possessions to Yuka. When the Wolf Imagin travels to the past, Gun Form is the first to confront him, stopping the Wolf Imagin from completing its mission.
After being stuck for a day in the past with no new information from Kai of Yuto Sakurai's location, the Wolf Imagin goes berserk in severe boredom-induced rage and decides to just destroy anything in his path to complete the mission. Although both Rod and Ax Form fought the Wolf Imagin, Sword Form is the one that finally destroys him.
The Wolf Imagin later returns in the Kamen Rider Den-O Hyper Battle Video, seen amongst the other Imagin aboard the DenLiner and interrupt the exercises around Ryutaros' turn. After mocking Ryotaro, he is destroyed by Den-O Liner Form. The Wolf Imagin is also one of the two antagonistic Imagin featured in the Imagin Anime 2 shorts, making two appearances, as well as in merchandise from Animate.
