History
"Rubber Ducky" is an aquatic add-on to the Iron Man Armor that allows it to travel safely through water. Used by Tony when Attuma attempted to flood New York, Falcon made fun of the name.[1]
Notes
- Rubber Ducky appears to be based on one of the adaptations of Earth-534834's Iron Man's Modular Armor and subsequently the original Hydro Armor Earth-616's Tony Stark built for underwater travel.
- Rubber Ducky's color scheme is later changed to resemble Earth-199999's Iron Man's Deep Sea Suit
