The Great Vegetable Disinteagrator (1967)
Day of the Locusts (1967)
Man of Steel (1968)
The American President James Norcross (voiced by Paul Frees) is given superpowers as the result of a cosmic storm. The President now has increased strength and the Metamorpho-like ability to change his molecular composition at will to any form required (like granite, steel, ozone, water and even electricity). A hidden panel in the Oval Office allows him access to his secret base, a hidden cave beneath the "Presidential Mansion" (a somewhat modified White House). Super President travels either by using a futuristic automobile/aircraft/submarine called the Omnicar, or by using jets built into his belt.
Despite the fact that the character's name is "Super President," for some reason only Norcross' chubby, pipe-smoking advisor Jerry Sayles knows that the leader of the Free World is also a red and white-costumed superhero in his off-hours.
