Microwave Man was a villain in DC's Action Comics in 1978, gathering his power from broadcast microwave energy (think about how much stronger he would have been now, or even stronger when 5G deploys!) Technically speaking, he even kicked Superman's ass (though there were some mitigating factors involving time travel, aliens, and well... Read the plot here).
How did this work, you may wonder? Quoting from the comic book:
Padgett is absorbing so many microwaves they're literally stoking up his molecular structure...as if he were a human atomic furnace!*
*Similar to the manner in which microwave ovens cook food -- by agitating molecules to produce heat!
Do we need to add... don't try this at home?
