Kamen Rider × Super Sentai: Ultra Super Hero Wars was released with much anticipation, given its ambitious crossover between two beloved franchises—the Kamen Rider series and the Super Sentai series. Upon its initial release, the film received a mixed to positive reception; fans praised the high-energy action sequences and the nostalgic nods to various hero generations, including the performances by Akio Otsuka as Champ - Oushi Black (voice) and Koji Yusa as Urataros - Kamen Rider Den-O Rod Form (voice). However, some critics felt that the complex storyline involving the "Arena of Death" and the intertwining of real and game worlds made the plot somewhat convoluted for casual viewers. Over time, the movie has gained appreciation among dedicated fans for its scale and creativity in merging two universes. It is now considered an underrated gem within the tokusatsu genre, cherished for its imaginative battles and character interactions that celebrate the legacy of Kamen Rider and Super Sentai heroes.
