The Hulk, who gets his strength from gamma radiation, usually tops the list of the strongest superheros. A lot of other superheroes and villains in Marvel Comics get their power from gamma radiation, like She-Hulk, the Abomination, and Doc Samson.
One under-appreciated gamma powered hero, though, is Sasquatch. Sasquatch was originally a Canadian physicist named Walter Langowski. While playing around with gamma radiation (as physicists so often do in the comics), Walter gained the ability to transform into a giant, orange-furred musclebound monster who looks just like the cryptid Bigfoot. Assuming the name Sasquatch, Walter uses his super strength to fight crime with a band of other Canadian heroes called Alpha Flight.
But that's not the only trait they share. Like Walter Langowski, the real-life Sasquatch or Bigfoot is also fantastically strong, as this example from Joseph Citro's Weird New England shows.
Bigfoot has been seen quite a few times in a Longmeadow, Massachusetts area called the Meadows. The Meadows abuts the Connecticut River, and many locals have seen large hairy humanoids swimming in its waters. Others have seen hairy faces peering into their windows at night, and found footprints leading from their houses down to the river the following day. Some residents speculate that the creatures inhabit a series of tunnels that run under the riverbanks.

A man named Joe operated a car crushing business in the Meadows for many years. One summer night he and some friends were sitting outside the office trailer enjoying some beer when they heard something moving through the bushes by the river bank. Abruptly, a large man burst into the car crushing yard. But was it a man? Although his bearded face looked human, he was eight-feet tall, naked, and covered with hair. It was a Bigfoot.
The Bigfoot wandered around yard for a while before picking up a crushed car chassis. Joe and his friends gasped! The crushed car weighed more than 2,000 pounds. The Bigfoot eventually put it back down and walked back to the river, where he swam away into the night. The next day Joe shut down his business and found a new location in town.
The Bigfoot seen in the Meadows was not a gamma-radiated anomaly - many people who see Bigfoots claim they are very strong. For example, in his book Passing Strange Joseph Citro mentions a 1951 Bigfoot encounter in Sudbury, Vermont where a Bigfoot moved a 450 pound oil drum.
To sum up, don't mess with Bigfoot because he's wicked strong - and he's not confined to the comic books.
