General Ernest Abercrombie is a supporting character and the commander of Area-86, Retroville's military installation. His military insignia gives him a rank of a Lieutenant General.
In the series, he had a major role in episode The N-Men, taking the N-Men except Jimmy to area-86. He then was seen leading the army against Hulk Jimmy (just like Gen. Ross leading the army against the Hulk) after seeing that Jimmy is too strong for them he let the N-Men handle Jimmy. But he said (the army) get lucky the N-Men will destroy each other.
- His lack of military tactics and/or professionalism could be an ode to General James Abercrombie, who was a British Army general and commander-in-chief of forces in North America during the French and Indian War, best known for the disastrous British losses in the 1758 Battle of Carillon.
- He and Mayor Quador were both voiced by Mark DeCarlo and Jim Cummings.
