Looks like a solid plan! Edison had a fairly considerable fortune because of his role in thwarting the Martian invasion of 1912, though he spent much of it on unwise investments like humanoid battle robots.
Your group will be joined by four support characters, who will help you with various behind the scenes tasks:
Morgan Elevrate, Transport Specialist: Captain Morgan is an independent agent contracting with WAHMO, who pilots her airship, the Starspear, as well as a rocket powered helecopter called the Crimson Comet to get the group from place to place when needed. She is a disorderly, drunken woman with an intense sadistic streak, but she's one of the best at what she does, and her record from the war is unimpeachable.
Polygram, Communications Specialist: The superheroine polygram has the superpower to control cables using magnetism, and extrude them from her body at will. Using her radio powers, she is capable of sending telegrams wirelessly anywhere in the country by thought alone, as well as tapping into vast communication networks. Despite her superpowers, she is unwilling to go on adventures unless absolutely neccissary, and prefers to spend her days at the top of a radio tower surronded by thick spiderwebs of steel cables.
Colonel Edgar Cassidy, Military Liason: Colonel Cassidy is the team's military advisor, and is responsible for keeping track of any intellegence the team gains regarding national security. He is a conservative man, who likes to play by regulations and pursue the doctrine of "peace through superior firepower." He is also responsible for determining if the interests of national security would be better served by sending the team to Korea, should their body count become excessively high. Col. Cassidy doesn't care about collatteral damage, since anything the heroes destroy is government insured, and any property damage gives him plenty of fun paperwork to fill out.
Meltdown, Scientific Advisor: Meltdown is an Atomic Hero based out of the Los Alamos laboratories, and he is capable of handing any particularly complex scientific questions the activities of the group invoke. Meltdown, like Polygram, has a minor case of Atomic Psychosis, and is unfit for full duty. Using his powers of matter manipulation, he can quickly produce even large amounts of exotic elements, though he is better at drawing up schematics than actually assembling prototypes.
