The Toxic Avenger (1984)

Going even further back in time, we find another superhero flick, although of a different tone "“ a lot campier than Darkman, The Toxic Avenger is as funny as its name suggests. The premise seems taken out of an Adam Sandler movie "“ a mop-boy at a health club falls into a vat of toxic waste, after being pursued by some evildoers.
After falling in the chemicals pit at the health club, the mop-boy transforms into a super-strong and super-big and super-disfigured creature, becoming the Toxic Avenger.
The movie was supposed to be a horror one and it does retain some horror elements. However, it is not one. It didn't meet such a great success when it was released "“ however, it did gather a cult following in the years which came after. It even spawned its own animated series.
