Endurium is an exceptionally rare and little understood metal alloy. It is almost dark as obsidian, but has a silvery sheen. Very few scientists know how the alloy is made, and even fewer are capable of creating it.
Endurium is extremely durable and is nigh indestructable. It can withstand tremendous force and intense heat alike.
The Bulldozer is able to alter his molecular structure, creating an armor skin of Endurium.
