Notes:

The source of Mettle's powers was never revealed.

Early solicitations referred to him as "Fortress", presumably a preliminary name.

Mettle was apparently killed by Arcade in the first strike of Murderworld from Avengers Arena #1. However, his unique physiology persevered and he returned alive in Avengers Academy Infinity Comic #15. After a period of serving as Emplate's meal, his powers altered to the point where he can change between his metal and human forms.
