Mark II

The Mark II (2) is a prototype for what would-be the Iron Man franchise, and was quickly replaced by the Mark III. It is prone to failure described by Tony as "the icing problem." It has no paint and needs a better arc to be powered than the Mark I. Its user, Tony Stark, used it for a "test subject." When it had its test flight, it had an "icing problem." It is prior to the Mark III, and subsequent to the Mark I.
