This article is about a/an monsters in Kamen Rider Build.

The unidentified Fang Smash (ファングスマッシュ Fangu Sumasshu) [1] was the first Smash encountered by Sento Kiryu, seen only by flashback. Its Smash essence was used as the basis for an unknown Fullbottle.

Character History

As seen in a flashback, it was loose in the city when Sento was sent after in by Soichi Isurugi as his first opponent. Though it beat him up while unarmored, after transforming into Kamen Rider Build, Sento easily defeated it. Who Takes Off The Veil?

Behind the Scenes

To be added


  • Its name is a reference to how the incomplete section of Square Smash's head brings resemblance to a lower jaw. Because of this, it is also suspected as the basis of Lion Fullbottle.
