History
Dr. Hank Pym was a scientist who was present for Dr. Otto Octavius's demonstration of the latter's fusion reactor. Prior to the beginning of the demonstration, Dr. Pym asks if Doctor Octavius could be vulnerable to the advanced artificial intelligence of his mechanical arms. Pym also mentions that he had recently developed a cybernetic helmet that Otto could've used instead of the inhibitor chip. When the experiment goes horribly wrong, Pym seemingly disappears from sight and suddenly reappears after the accident is over, checking Octavius's pulse.
Notes
- Pym's "sudden disappearance and reappearance" implies that he has already discovered the Pym Particles in addition to creating his helmet, and may already be or about to become Ant-Man.
