- —Gustave Eiffel[src]
Gustave Eiffel was the designer of the Eiffel Tower. Eiffel continued his life by becoming a Zombie-Robot.
Gustave Eiffel designed the Eiffel Tower which was secretly a spaceship. Long after his supposed death, Eiffel used the Eiffel Tower to kill citizens in Paris, causing The Umbrella Academy to intervene. During the fight, Number One broke through into the Eiffel Tower's control room and found Eiffel controlling his contraption. Number One had suspected that Eiffel was behind the Eiffel Tower's rampage, while Number Six was surprised that he was alive after all these years. Number Two killed Eiffel by throwing a knife into his forehead, causing Eiffel to trigger the Eiffel Tower's launch sequence.
