Last seen in Ant-Man and Civil War, Howard Stark makes an appearance when Steve and Tony travel back to 1970 in search of the Tesseract and more Pym Particles. Tony runs into his father and the two bond over being fathers — though Howard has no idea that the child he's expecting is the man he's speaking to at that moment. Their conversation seems to bring closure for Tony over their tumultuous relationship and strengthens his desire to save the world for his own daughter.
