Waldo and Magic Inc.

Fat, Ugly, and Hopeless Crippled On Earth
Waldo F. Jones floated like a seraph in the only place in the Universe where he was truly free...the incredible zero-gravity home mockingly called "Wheelchair" by those who hated him.
Born the victim of a strange muscular atrophy, Waldo now ruled nearly the entire planet. For, like it or not, those hairless apes called men desperately needed him and the preterhuman genius they could not begin to understand.
Waldo was willing to help, all right, but only at a price. Those pitiable earth creatures owed him something, and at least they'd pay for it...they'd pay but good!
