Shockwaves

Shocker was one of the numerous supervillains who pretended to be Defenders for a Day. A recurring foe of Spider-Man, this particular Shocker had no connection to the member of Mutant Force also known as Shocker. Though not necessarily shocking, it was uncommon to see two characters with identical codenames active during the same time period.

The original Shocker appears in these panels from Defenders #64 (Oct. 1978).
