Frog-Man.
Let that name sink in for a minute. Not really a terrifying name is it?
Well apparently that little fact, not to mention the re-donk-ulous frog suit, didn't stop one Eugene Patilio from naming himself that, and deciding to do his part to rid the world of crime.
No, seriously.
It seems Mr. Patilio's dad was once a super-villain named Leapfrog.
He was a failure as a regular criminal, who graduated into a super-failure once he invented a special electrical coil system that allowed him to jump high distances and don a giant frog suit.
As was to be expected he never amounted to much, becoming a regular punching bag for various heroes, but primarily Daredevil.
Thankfully he decided to give it all up after the many numerous beat-downs he received.
This is is where his son Eugene comes into the picture. Feeling really ashamed and embarrassed because of his father's failed career as a super-villain, Eugene decided to go the other way, and become a superhero in order to atone for his father's actions.

And thus the scourge of all super-villains was born.
No, not really....
Frog-Man first appeared in Marvel Team-Up#121 (September 1982), created by writer J.M. DeMattesis and artist Kerry Gammill.
One time Frog-Man tried to be Spider-Man's sidekick, but found competition for the "role" in the unlikely form of the Toad.
No, you read that right.
Froggy and the Toad(Magneto's former lackey whipping boy from the first Brotherhood of Evil Mutants) battled it out to be Spidey's sidekick.....to Spidey's doubtless frustration.
Other than that, Froggy's popped up here and there over the years, most notably during the Fear Itself event, where he was a part of a volunteer group of heroes trying to capture Crossbones, who escaped from the super-villain prison facility, the Raft.
He also appeared during the whole Spider-Island incident, where he teamed up with some Avengers to stop an attack by the evil terrorist group Ultimatum and Flag-Smasher.

Other than that, I imagine he can be randomly seen, jumping around, trying to stop some poor, confused criminal or criminals. They probably think they're high or seeing shit. But nope. It's Frogger come to life.
YOLO I guess;)
And with that, despite his big heart and noble ambitions, I just have to say to both Mr. DeMatteis and Mr. Gammill.....
Gentlemen, What The Fuck Were You Thinking?
Hope you guys have a good/great weekend, and stay safe:)
