The Stretch Smash (ストレッチスマッシュ Sutoretchi Sumasshu) is a Smash with several different forms and identities.
An unidentified Touto guard was transformed into the Stretch Smash Hazard by Night Rogue. He was freed after being defeated by Kamen Rider Cross-Z. He targeted Misora Isurugi who was caught in the battle against the Kamen Riders, knocking her out before being defeated and restored back to human by Build and Cross-Z combining their finishers.
A Stretch Clone Smash was one of the Clone Smash created by Nariaki Utsumi, based on the original while lacking a human host. Alongside the Press Clone Smash, it was summoned by Blood Stalk to fight Kamen Riders Build and Grease during the battle for the Pandora Box. They were ultimately destroyed by Ryuga Banjo when he used the Cross-Z Magma Knuckle to become Cross-Z Magma.
