Stretch Armstrong & The Flex Fighters Wiki

Flexarium is a substance conceptualized by Dr. Racine Cleo and further researched by Jonathan Rook and his company. It serves as the main source of superpowers displayed throughout the series.

Overview[]

Flexarium is an incredibly durable and versatile compound. It can stretch to great lengths while still retaining its strength. It can be lighter than air or as dense as lead. Rook found uses for Flexarium in construction, vehicles and even military clothing.

Jonathan incorrectly believed that Jake, Nathan and Ricardo's specific body chemistries naturally fused with Flexarium to give them their powers.

It seems to melt at high temperatures.
