Stephen Wilcox appears in the third episode on the I-Jin fortress, making a minor appearance as the builder of many of the I-Jin machinery, including Otto Lilienthal's Glider, Genjō-sanzō's heart mechanism (never directly stated, but very likely), and the I-Jin Fortress itself, which appears to be steam powered instead of nuclear powered as Joker implies. He is portrayed as being built into the Fortress and visibly insane.
