Someone very important to the following characters has been infected with HIV:

Reed Richards...Susan Richards has been infected.
Bruce Banner...Betty has been infected.
Doctor Doom...he himself has been infected.
Bruce Wayne...Alfred has been infected.
Lex Luthor...he himself has been infected.
Superman...Lois has been infected.

If such a thing ever occured (lets assume they all learned of it at the same time), who would be the 1st to come up with a complete cure to the disease?
