- "Even a Wookiee can't crush First Order armor."
Betaplast, also known as Composite Betaplast, was an armored material that comprised the armor of the First Order's stormtroopers. Offering improved protection over Imperial plastoid, Betaplast was known for its ballistic qualities and high-impact resistance, and was claimed by Phasma to be so strong that not even a Wookiee could crush it - though when threatened she relented rather than test this claim.
