Marvel Chronology Project

Black Knight (Nathan Garrett) is listed as being taken by Zarrko the Tomorrow Man in FF 405 from between Avengers 15 and 16, but reading the issue, the character is clearly Percy, the first Black Knight, who is taken at an unknown time. The Appendix site places it after Marvel Chillers, and has additional issues that could be added to Percy's chronology.

I just flipped through FF 405 and the Black Knight appearing there is in Percy's suit; Garrett's suit has a blue cape with crossed swords on his chest, Percy's has a red cape, no crossed swords and a different helmet.
