It's time to Be the One! Sento creates the Cross-Z Build Can to merge the powers of Kamen Rider Build and Kamen Rider Cross-Z's Rabbit and Dragon powers. The Cross-Z Build Can functions similar to the Rabbit Tank Sparkling Can. Pop the top to activate the activation noise, and insert into the Build Driver to start the transformation. Rotate the handle again to activate the "Love and Peace Finish!" attack. Shaking the can will make the toy say one of 30 phrases between Sento and Ryuga.
