Bismarck's Geass allowed him to see up to a few seconds into the future. He mainly used it in combat and despite piloting an inferior Knightmare Frame was able to fight Suzaku before the latter took advantage of his own command to "Live", an order cast on him by Lelouch, to fight on even terms. Bismarck claimed that Suzaku was the first person since Marianne he had to use his Geass against. Though this implies that he used it only sparingly, Bismarck still restrained his Geass by sewing his left eyelid shut, suggesting that it could be permanently active.
