Evil Lincoln

Evil Lincoln is an evil incarnation of Abraham Lincoln by the Holo-Shed on Nimbus, who appears when the simulation malfunctions and the simulations become real.

When Kif Kroker was showing his smizmar, Amy Wong, the programs he had written for her in the Holo-Shed, Evil Lincoln, along with the rest of "History's Greatest Villains" appeared during a simulation malfunction and caused mayhem aboard the Nimbus, which ultimately lead to Turanga Leela's impregnation of Kif Kroker.
