Hammer and Anvil first appeared in Hulk #182 (December 1974), and were created by Len Wein and Herb Trimpe.
The two begrudgingly work together to escape prison and later inadvertently save a metal-eating alien who replaces their chain with a device that grants superhuman powers.
[7] Hammer and Anvil kidnapped Amanda Sheridan for the DRC, and fought Spider-Woman.
Alternate universe variants of Hammer and Anvil from Earth-1610 appear in Ultimate Fantastic Four #49.
These versions are Russian and missing opposite arms, with bolts of energy linking them on their limbless sides like a diode.
