Meet your skipper: Nikolia
Following his accidental exposure to gamma radiation during the detonation of an experimental bomb, Nikolia is physically transformed into the Grebublin when subjected to emotional stress, at or against his will, often leading to destructive rampages and conflicts that complicate Nikolia's civilian life. The Grebublin's level of strength is normally conveyed as proportionate to his level of anger. Commonly portrayed as a raging savage, the Grebublin has been represented with other personalities based on Nikolia's fractured psyche, from a mindless, destructive force, to a brilliant warrior, or genius scientist in his own right. However, his uncontrollable power has brought him into conflict with his fellow heroes and others.
